Re: [PythonCE] Accessing serial port with PythonCE 2.5

[Adam Walley]

Hello,

Just to add to my previous message, the ceserial module uses ctypes to
access the same functionality which would be used by a WinCE application
written in VB or C#. I have just checked and Microsoft appear to still have
the reference pages available, so you may find that the following link can
guide you in checking the serial communications:

https://msdn.microsoft.com/en-us/library/aa450503.aspx

(I am assuming WinCE version 5.0, but I think WinCE 6.0 and later versions
will also be available)

For checking your device is communicating as expected, you could try to use
a third party terminal program that can also access the serial port. I
recall using vxHpc and also PocketPuTTY. These can be installed directly
onto the WinCE device and allow you to test the serial port. Then you can
try connecting the WinCE device directly to a computer to check
communication settings are correct, then connect your serial device
directly to a computer (just the regular troubleshooting steps really).

Good luck

Re: [PythonCE] Accessing serial port with PythonCE 2.5

[Adam Walley]

Hello,

I thought I would send a short comment, as I have used the ceserial module
(a long time ago) for my HP iPaq running PythonCE 2.5. I recall that the
ceserial module tries to implement what the standard serial module does for
Python, but depending on the actual version of ceserial used there may be
some small differences in the naming of the of the properties and
variables. It is worth verifying in the ceserial module that it is actually
settings the parameters as expected for the serial port object.

That aside, I would also say that a PARITY_EVEN setting would be unusual
these days and that PARITY_NONE is more common. I think I also found that
the stopbits setting did not set the port as expected. Sorry to not have a
definite answer, but an oscilloscope will show you what the device is
trying to do. Finally, perhaps the device you are connecting to is
expecting the DTR line to change?

Re: [PythonCE] Installing python on Windows CE 7.0 device.

[Adam Walley]

Hi Sachin,

Was wondering if you got this working? I would be interested to know
whether it can be done for WinCE 7.0.

Regarding the error with COREDLL.dll, if you are lucky this is just an
issue with upper/lowercase. You could try renaming your COREDLL.dll file to
coredll.dll, or Coredll.dll

Unfortunately, I suspect that the problem may be more than just the above.

Re: [PythonCE] Input problem

[Adam Walley]

Hello, Ivan.

Welcome to PythonCE. From your message, I think your script is probably
working fine. The problem is that blasted dialog, which is covering your
output. A very simple workaround is to add a few blank lines before printing
your x value, so that it appears below the dialog (I know this works on a
PDA, but maybe the screen size is different on a mobile phone?). Your code
might look like:

x = input(Enter value)
print 10*\r\n # prints 10 blank lines
print x
raw_input(Enter for exit)

Alternatively, you might want to add a short pause before the exit:

import time
x = input(Enter value)
print x
time.sleep(2) # wait 2 seconds
raw_input(Enter for exit)

  I am started a weeak ago with python, and yesterday I wodnloaded for my
 mobile.
 However I feel that something got wrong. The problem is that when I run a
 script on computer that requires input, prints something and agains require
 input (that second just prevents from script closing before reading output),
 i get what I want - example :
 Enter value10
 10
 Enter for exit

 That's not the case with pythonCE. It creates dialog, I enter value,
 nothing is printed out and I am again prompted for exit. I find that quite
 strange as it's the very same code and it acts like after input is output or
 all commands ignored.
 My code:
 x = input(Enter value)
 print x
 raw_input(Enter for exit)

 Thanks for help as this is an issue I can't move along with..

Re: [PythonCE] PythonCE - I'm a subscriber

[Adam Walley]

Hi, Ihsan.

Welcome to the list. I am not sure what you mean by programming without the
''s, but I have a feeling that you mean the Python interpreter is not
associated with .py files. Once the association is created in the registry,
you can launch .py files. I use WM5, but I think WM6.1 will probably let you
do this too. To create the association in the registry you need to start the
Python interpreter on your device, and yes you need to use the ''s, but
only for these steps:

 import _winreg as reg
 k=reg.CreateKey(reg.HKEY_CLASSES_ROOT,'.py')
 reg.SetValueEx(k,'Default',0,reg.REG_SZ,'Python.File')

k=reg.CreateKey(reg.HKEY_CLASSES_ROOT,'Python.File\\Shell\\Open\\Command')
 reg.SetValueEx(k,'Default',0,reg.REG_SZ,'\\\Storage
Card\\Program Files\\python.exe\ \%1\')

DISCLAIMER: please be aware that modifying the registry can cause serious
problems with your operating system. Do not undertake any changes unless you
know and understand what you are doing!

The above lines of code may get broken through the email and/or mailing
list, so check them carefully! Also remember the underscore for the
'_winreg' module name, and look carefully at the string value you need to
enter for the path to the Python.exe file - there are single AND double
quotation marks.

When you have completed the above steps, you should be able to launch a
simple .py file containing Python code without needing to open the
interpreter first.

Note that I prefer to run my Python executable from an SD card, so the
registry path begins with '\\Storage Card\\Program Files\\...', but if your
Python.exe is located on the main device, the value will probably simply
begin '\\Program Files\\...'.

Alternatively, if you are able to establish an ActiveSync link with your
computer and device, then you can download a registry editor to make the
task easier (e.g. CERegEditor by MDSoft is one, but there are many).

Now, writing and editing .py files is another matter...

[PythonCE] PythonCE and SSL

[Adam Walley]

Success!

Using the TLSLite package I was able to achieve what I was aiming for - that
is to access Gmail programmatically from PythonCE. For anyone interested,
this is how I got there (after quite a bit of puzzling and trawling through
the net):

Having downloaded the TLSLite-0.3.8 package, I placed the 'tlslite' folder
into my 'Lib/site-packages' without any modifications. Now it would be
accessible to any of my PythonCE scripts. Next, I wrote the following
script:

-- Example PythonCE code --

import base64, string
from tlslite.api import *

user=anyuser
passwd=whatever
h=HTTPTLSConnection(mail.google.com,443)
auth=Basic +string.strip(base64.encodestring(user+:+passwd))
h.putrequest(GET,/mail/feed/atom)
h.putheader(Authorization,auth)
h.endheaders()
r=h.getresponse()
txt=r.read()
msgs=txt[txt.index(fullcount)+11:txt.index(/fullcount)]
raw=raw_input(inbox(+msgs+))

-- Example PythonCE code --

the above simply connects on port 443 (https) to the Gmail atom feed and
returns an XML message about new messages in the inbox, which is then
searched for the number of new messages. It's not the fastest thing in the
world, but it works.

Re: [PythonCE] Beginner Questions

[Adam Walley]

Welcome, Christopher!

I hope you like what you have seen so far with Python and PythonCE. To
answer your questions:

- Yes, the setup executable is intended to work through Activesync, so next
time you connect Activesync will do the install on your device for you.

- Running the setup executable directly on your device will not work
(because it is compiled to run on a PC and then transfer through Async). To
install directly on your device you need a CAB package (I seem to have one
for PythonCE 2.5 in my original install files so it is probably available
out there somewhere).

- PythonCE is definitely not only for smartphones, although that is a
popular use for it. Any platform that runs Windows CE or Windows Mobile
should (hopefully) let you run PythonCE without any problems. PythonCE will
not run on Symbian or Android phones because PythonCE needs Microsoft's
operating system - there may be other Python packages for these platforms
(but that's not anything to do with this list).

- Your objectives are not unreasonable, although depending on your exact
requirements you may find stand-alone to be a sticking point; the target
device will need to have PythonCE installed before any scripts will run on
it, and there is no method for making a single executable file from your
script (as you might do with a C compiler, for example).

- Java and C experience will certainly be useful.

- Documentation is mainly what you find on the wiki and sourceforge pages,
as well as the main Python pages (most things are implemented the same way
in PythonCE). Many things are covered in this list.

I have some personal pages I put together, which may be of interest -
including how to record from the built-in microphone and save out to a WAV
file, as well as stylus input. There is also information about using the
system's notifications to schedule a script to run at a certain time. Take a
look here: http://watersprite.awardspace.com/python

Happy Python-ing!

 relatively elementary questions.

 I found what looks to be the newest download called pythoncesetup.exe.  It
 ran on my PC under Windows XP and upon finishing says it will install
 PythonCE the next time I attach my PDA.  Is this done somehow through
 ActiveSync?

 I tried running pythoncesetup.exe on my PDA directly using a thumb drive.
  I got an error that the program was not a valid win32 application.  Is this
 expected behavior?

 On the Python wikki, I found a lot of files that seem to be a smartphone
 application.  Is PythonCE only for smartphones?  What about Symbian phones
 or the Google phone and droids?

 Right now, I'm mostly learning Python using the ActiveState Python 2.6 on a
 PC running XP and Ubuntu Linux.  My longer term objectives are to:

 Create stand-alone applications on mobile phones that allow blind,
 visually impaired and numeracy impaired people to gather data from medical
 equipment and have it spoken from their cell phones or PDAs

 Explore the use of PythonCE on a braille PDA running Windows CE 6.

 Do these seem like reasonable objectives?

 I have experience programming in Java and C, assisted in the implementation
 of the FORTH language on a braille-based PDA, so am not a complete stranger
 to this work.

 Any advice, particularly pointers to documentation, would really be
 appreciated.

 Thanks.

Re: [PythonCE] kbhit type of functionality in PythonCE

[Adam Walley]

Hi, Cazaw.

Welcome to PythonCE. I remember wrestling with similar issues with the
raw_input. AFAIK its features are very limited and it does rather awkwardly
appear over the PythonCE window. You can, of course, position your text
output with some spacing.

If you are satisfied with just a pause before the raw_input window appears
then you can import the time module and use the sleep function (although
this tends to make the OS think the app is not responding). I usually create
a simple loop function instead, when using this method. It would define a
pause function and look something like this:

def pause(t):
   t0=time.time()
   while time.time()-t0t:
  pass

where 't' is the number of seconds to pause (and can be a decimal if
needed). Then you just call the pause function at the point in your code
where you want to wait.

Unfortunately, I think that any other method whereby (hard or soft) key or
stylus input is used would be non-trivial and requires quite a bit more
effort.

If you have the time to put into it, I would suggest looking into the
PocketPyGUI package or compiling the SDL library and using that (I have some
info on using SDL with PythonCE here: watersprite.awardspace.com/python).
Perhaps other list members have some other suggestions?

Adam.
2009/10/29 Cazaw cazaw_...@yahoo.com


 p.s. - Alternately, if the raw_input could show up in the stdout along with
 the displayed results instead of it's own dialog box, that would be just
 fine and eliminate the problem. Whichever way would be easiest.

 I wonder if there is a simple script that can act as a console that
 takes input from the port (telnet) and output the data to the port
 also.

 Like a io redirection, so I can just telnet to the WM6 to do script
 development instead of typing on the tiny keyboard.

[PythonCE] pygameCE / SDL question

[Adam Walley]

Hi, all.

Apologies if this post is a little off PythonCE topic, but I am not sure
where in the SDL groups I might send it. I thought Rene might have some
ideas?

Having had some success in getting some basic things working using PythonCE
and the SDL library, I decided to persevere. Having recently started using
VS2008, I was finally able to get the SDL library for winCE compiled. My
previous tests all work with this new library (now version 1.2.13), and at
least I know what functions have been included and should be available to
PythonCE.

My question is about what happens when an SDL window is initialised.
Previously, using the knakos library, I was able to initialise a window
which did not occupy the entire screen. However, using my new library, it
seems that I am forced to use fullscreen only. This is perhaps not such a
great problem for most pygame applications, but it really bugs me that the
non-fullscreen method no longer works.

I think that the knakos library uses some 'tricks' to allow the SDL screen
to be defined as any rectangle within the device's display.

Could somebody explain, how this is achieved, and how much work might
be involved in modifying my 'vanilla' library to do the same?

Re: [PythonCE] pygameCE / SDL question

[Adam Walley]

Hi, Jared.

No, no changes. I simply compiled using the Visual files supplied in the
download. I then ran my demo sliding tile app (exactly the same script with
a single change to point to the new DLL) and it all works, but in fullscreen
only. That is why I suspect there may be some 'adjustments' made to the
knakos library, or possibly the newer SDL version has changed some of its
default behaviour.
Which version did you compile? The knakos one is 1.2.6, and my latest one is
1.2.13.

Adam.
2008/9/24 Jared Forsyth [EMAIL PROTECTED]

 I've compiled a version of SDL (granted, its not the latest one) -- but
 non-fullscreen works out of the box. Did you make any modifications to the
 core library in porting it?

Re: [PythonCE] pygame / distutils

[Adam Walley]

Hi, Rene.

Thanks for the clarification on pygame-ctypes. The link where I found the
SCUMMVM SDL libraries is here:

http://users.uoa.gr/~knakos/scummvm/libraries/release-0-10-0/wince-gcc-libs.tar.bz2

There are a number of files in there, including a .diff file which may shed
some light on some of the difficulties in compiling the SDL libraries. The
SDL version used is 1.2.6. I believe the latest one is 1.2.13, but I think
this should not be a big issue to update later.

As far as my progress goes, I have got a small pythonCE script running,
which draws some coloured squares to the screen (kind of like one of the
slide transition effects in powerpoint). The busy indicator no longer
interferes with the display :D

Now, I am working on a bit of code to allow user input. I am adapting the
code to allow key presses of the PDA's hardware function keys to be
detected. I would like this to be a small module that can be used in
PythonCE to get the scancode from any key press (from the SIP or the
hardware keys). I know that SDL provides this, but I am not sure if it will
allow the hardware keys to be detected.

From what I understand, there is some extra work in writing a PYD module, in
contrast to writing a DLL that is called with ctypes. I have not looked into
this in great detail yet, but ultimately, I would like to get some DLLs
written in the correct form so they can be used as PYDs. I guess there are
some basic rules for Python to 'talk' with its package modules.

Anyhow, your plan sounds good, so if there's any way I can help just let me
know.

 What is the best way to compile extensions for python CE ?

 Adam: do you have a link to those SCUMVM files?

 Any further progress?

 Why not pygame-ctypes?  It was slow, buggy, and non-portable - and C
 pygame worked fine.  The author was paid to do it, and stopped when
 the money ran out and moved on to pyglet.  pygame has a bunch of C
 code which just can't run fast enough in python.  Pygame is not just a
 SDL wrapper, it's got a bunch of other code in it too.  ctypes has an
 overhead for each call which is annoying for real time apps.
 However... pygame-ctypes is still useful for some things, and if pypy
 ever gets fast it will become more important (assuming they never
 release a C api for pypy).

 anyway...


 I'd going to try the following order of things...
 - get a simple C program to compile and run on the device.
 - get a simple C python extension module working.
 - get a simple SDL program working.
 - get some pygame modules running.
 - get full pygame test suite working.
 - port pygame example programs so they work ok on pythonCE too.

Re: [PythonCE] DLL hourglass in ctypes

[Adam Walley]

Well, my initial question certainly seems to have stirred some interest.
Thanks to everyone for the input. I think what I can draw from all this is
that:

1. The hourglass/busy icon is useful to give users an indication of when the
application is busy 'grinding' away at something and user input is not
expected/possible at that time - as in the application John described in a
previous post.

2. The hourglass/busy icon is NOT helpful when the application is doing some
processing that involves some visual effects, since the hourglass/busy icon
then interferes and obscures the display. This is a nuisance, when the
application is trying to display something on screen (whether it requires
user input or not). I would say most pygame applications fall into this
category (and the idea of pygame for PythonCE is what prompted this post in
the first place).

My conclusion would be that while there is no harm in having this icon
appear by default, it cannot be left to the system to decide when the icon
should appear. Therefore, a method of 'disabling' the icon, at least for the
duration of the execution of a script, would be useful.

Jared kindly pointed out that the ppygui package already has this covered,
so at least in the first instance I will see whether I can combine what I
have built so far with ppygui to see if I can achieve a satisfactory result.

Thanks again to all.

Adam

 interpreter can (and should) take care of this.


 Ah, this rings a bell.

 I think according to the Windows CE compatibility guide, you're supposed to
 show the hourglass until your application is ready for user input.

 I believe it's up to the application .py file, not any libraries or
 interpreter, to make the Busy(0) call.

 Only the application author knows how many modules need to be loaded and
 when the application really has started.

[PythonCE] cegcc on Debian etch amd64

[Adam Walley]

Hello, all.

I have not posted to the cegcc list before, but have been working on some
pythonCE projects, where cegcc might prove a useful tool (I hope). I realise
that the following is not really a pythonCE topic, but thought it might be
useful to some of the list's readers given some of the recent discussions.

This post was really just to confirm that cegcc can be compiled from source
(from the cegcc SF download page). I thought I should mention this, because
I did not see any amd64 packages for cegcc, and there were very few posts
relating to using cegcc with an amd64 processor or with debian (perhaps it
has gone so smoothly for everyone that no questions were asked?).

The steps I followed were:

- download the source package (platform independent)
- extract to a convenient folder
- I used 'su' privileges (though sudo might be ok too)
- run the 'build-cegcc.sh' script located in the cegcc/src folder
- if errors occur, just go through the output carefully to locate any
packages, which may not be present on your machine (I had to install 'bison'
and 'flex' using the usual 'apt-get install' command)
- IMPORTANT! before running the build script again, remove the 'build'
folder that was created in the 'src' folder during the initial failed build
attempt. If you do not do this the build script will almost certainly fail
again.
- it can take some time to build the entire package
- I think there were some minor warnings/errors, but the cegcc structure and
files all appeared correctly
- check that the files are there in /opt/cegcc
- if you want to be able to call the compilers from a Gnome terminal window
you need to add this folder to the $PATH variable. To do this, simply edit
the /etc/profile file (use 'su' or 'sudo' to do this) and add the following
line at the end of the file:
   export PATH=$PATH:/opt/cegcc/bin
The change will only take effect the next time you open a terminal window
- Now you can access the cegcc compilers from any folder. Type
'arm-wince-cegcc-gcc' to check that it works. The reply should be 'no input
files'
- Now I simply followed the 'getting started' steps at
http://cegcc.sourceforge.net/docs/using.html
- remembering to copy across the relevant DLL files to my PDA (cegcc.dll,
cegccthrd.dll, and libstdc++.dll)
- these DLLs will work if you put them in the same directory as the EXE you
want to run, but a more sensible place for them is the main Windows
directory. These DLLs add up to about 1MB, so you don't want to be
duplicating them too much.

That's it. I can confirm that the 'hello' dialog appears on my WM5 pda.

hth (especially, like me if you are still just a beginner, or you are
looking to get started quickly).

Re: [PythonCE] pygame / distutils

[Adam Walley]

Christopher and Jared,

Thank you for your comments. Christopher would you agree about the
sluggishness once pygame is running on a PDA? I suppose I am not too
bothered at the moment. For my purposes just being able to access audio and
drawing to screen would be fine - though I'm sure sooner or later speed will
be needed too.

One additional obstacle I face is some extra fiddling to get the compiling
done on PellesC (I do not own VS and I believe the free version does not
support WinCE compilation).

Anyhow, I will attempt to get something working, and if it gives respectable
results I will report back.

Thanks again for your input.

  - is there already a way to get distutils working with PythonCE?

 There has been recent discussions about this, but at current I don't
 bieleve there is anything available.

 With respect to SDL and pygame it should be fairly easy to get the various
 python modules compiled. There have been a couple of
 releases built for PythonCE in the past and I've personally compiled from
 source a couple of times.

 The SDL project has an additional ZIP file that contains Windows CE (Pocket
 PC) compatible project files that will allow you to
 build a suitable dll.

 If you look at the distutils based installation files for the pygame
 distribution you can determine which source files need to be
 compiled into the various python modules (*.pyd). What I did was then
 manually create project files for Visual Studio to build
 these DLLs (you will need a source release of PythonCE itself for this, as
 to build a module you will require the python header
 files).

 Once I had all the pygame dlls compiled it was then simply a matter of
 copying them to the correct folder on the PDA. There was no
 registry settings etc involved.

 One thing to keep in mind is that some of the sample apps within the Pygame
 distribution won't work on a PDA without minor
 modifications. For example they commonly request a window size which is
 larger than the PDA's screen, and don't account for the
 lack of current working directory support when specifying file names for
 bitmap resources etc.

 Hope this helps,
 Christopher Fairbairn

Re: [PythonCE] PPYGUI - parent window and closing it

[Adam Walley]

That's perfect! Thanks for your suggestions. I have adjusted the registry to
allow for .pyw files without the shell (CeRegEditor did the job). Now when I
run my code and press the 'X' in the top right corner, the whole thing exits
smoothly and fully - Great!

I didn't want to use tMan because that would mean that my users would need
to use/install it too. Binding the close signal to the app works very nicely
with the emulator without tMan, but not on my WM5 device (as you had
explained).

Thanks again for the assistance.

Adam.

2008/7/10 Alexandre Delattre [EMAIL PROTECTED]:

 Hello, Alexandre.


  I have begun testing some ideas using the PPYGUI and find it very easy to
 work with. However, I would like to ask if there is a way to know when the
 user has pressed the 'X' button in the top right of the window to close
 the
 app? The reason I ask, is that when I run some ppygui code a blank Python
 window opens, then the ppygui app window opens on top of it. When I close
 the app using the top right 'X' I am returned to the blank Python window.
 This is very similar to the situation on the desktop version of Python,
 where a terminal window opens unless your Python file is run with the .pyw
 extension.


  I can implement a 'close' button that executes the sys.exit() command, and
 this successfully closes the app and the blank Python terminal window
 together. Nevertheless that top right 'X' is still there, and I would
 prefer
 the users of my app to have something consistent and which behaves as
 expected (i.e when you press 'X' the app exits or at least is hidden
 fully).


  How do it detect this 'close' event for the main app?


  Adam


 Currently the best option is to install the tMan task manager 
 http://pda.jasnapaka.com/tman/ or others,
 which allow to close program when clicking 'X' instead of the default
 minimize behaviour which is problematic
 with PythonCE (other PythonCE gui toolkits have the same problem regarding
 this).

 PPygui has already some inner logic, which makes the 'app.run()'
 line returns when the main frame is closed (with tMan), so it'll work well
 with it.

 Unfortunately the .pyw extension is buggy on PythonCE due to a mis-written
 registry key,
 You can fix it with a registry editor of your choice, by setting the key:
 HKEY_CLASSES_ROOT/Python.File.NoShell/Shell/Open/Command/Default =
 \Program Files\Python25\python.exe /nopcceshell %1


 You can also intercept the 'close' event at application level (but still
 need tMan to work)

 import ppygui as gui
 class MainFrame(gui.CeFrame):
  def __init__(self):
   gui.CeFrame.__init__(self, title='Hello')
   self.bind(close=self.on_close)

  def on_close(self, ev):
   if gui.Message.yesno('Confirmation','Do you want
 to quit','question', self) == 'yes':
 ev.skip() # If user say yes, let the close event be further processed
 by the default implementation which will close the window for good


 Hope this helps,
 Alexandre

Re: [PythonCE] PPYGUI - parent window and closing it

[Adam Walley]

Alexandre,

Thank you for this news. I will update things tomorrow and see if it works.
Just to be clear, when I originally tested my app, the Python shell launches
and the ppygui app opens on top of it. I was able to go into
settings/system/memory and close the Python shell without affecting the
normal operation of the ppygui. Also, when I exited my ppygui app using my
sys.exit() button everything closes correctly and is no longer resident - I
checked this in settings/system/memory. When I used the 'X' then both the
shell and the app would remain resident until I terminated them manually.
This also prevented me from running another app until I had done this.

Using the registry tweak, the Python shell is not visible and it does not
even appear in the list under settings/system/memory; only my app's name
appears. When I exit, everything is closed normally whether I use my own
sys.exit() button or the 'X' in the corner, and nothing remains in memory
(unless it somehow stays there without appearing in the system's list).

These are my experiences specific to my iPAQ1950 running WM5 and PythonCE
2.5, so other systems may not behave exactly this way (though PythonCE does
seem to be quite consistent).

Anyhow, I think this problem has been resolved, so thanks again.

Adam

 Adam, there's one downside to not use tMan: even if the window disappear it
 is still running background and the only way to really close it is in the
 Memory app of the control panel.

 But rejoice, following this discussion I've been able to modify ppygui so
 that windows are really closed even without tMan :)

 Now, even a .py file will see it's terminal closed when the gui main frame
 is closed, without using tMan.

 Expect to see the code in svn in a few hours.

[PythonCE] serial input problem

[Adam Walley]

From: Adam Walley [EMAIL PROTECTED]
Date: 31 Mar 2008 13:15
Subject: Re: [PythonCE] serial input problem
To: Jan Ischebeck [EMAIL PROTECTED]

Hi, Jan.

Thanks for the reply. I am using 19200 baud, but I have also checked 2400,
4800, 9600, 14400, 38400, 57600 - same result. The other settings are 8N1
(set as 8,0,1 in the ceserial module). I have checked my modem settings to
see that there is nothing which could interfere, but AFAIK all seems ok. I
have made sure my wiring is ok too.

All these checks are good, but the fact is that my terminal program works
correctly, and PythonCE continues to give me these scrambled answers. The
first character usually seems to be correct, but after that it seems to be
garbage. The OK reply from my modem comes in as: 13 A1 6A 35 (in hex). If
I switch to numeric modem responses the modem replies with 0 instead of
OK. In this case, PythonCE gives me a 0 followed by a square (indicating
a character which cannot be displayed).

I feel like I am missing something simple, but just cannot put my finger on
it.

Just a note on encoding, my 'sys.getdefaultencoding()' is 'ascii' and my '
sys.getfilesystemencoding()' is 'mbcs'.

I hope you can help.

Adam

 Hi Adam,

 The begin of the modems answer in hex makes sense ( 0x0D = 13 = carriage

 But A1 6A 35 is neither raw unicode, utf-8 or utf-16 so I guess
 something is wrong with the line settings.
