Hi Shawn:
We are working heavily with serial ports on mono linux here at my Univ.
and so far all works kind of ok doing read/write calls , but now we
really need the incoming data event, but also be able to write to the
serial port, so we can't do threading loops makings reads on the port
Hi Mauricio,
Are implementation was for OSX and we did not implement events.
However we did make a threaded read and write that uses select on the
port to see if there is data.
Here is the where the code can be downloaded.

I hope this helps.

Hi Shawn:

Hi,
Sorry, We have meant to release the code, but it went on the back
burner and I actually forgot about it. Thanks for the reminder.
I guess if the patch works, then that is great.
Our implementation relies on a new .NET class that uses Unix calls.
If this is still needed we can release
Hello all
which is the status of the serial port in MacOSX implementation?
i think Shawn code is not released, and i wonder if patching mono with
this patch:
https://bugzilla.novell.com/show_bug.cgi?id=384227
and re-compiling Mono will work on Mac.
Worked for anyone? i have no MACs around.
Uhm...
Now I try the code below. It works on Microsoft Visual Studio, but not in
mono on Ubuntu.
It compile it, but when I try to run it I get this error:
Unhandled Exception: System.NotImplementedException: The requested feature
is not implemented.
at
The RecievedEvent is not implemented (check the exception...). If you
need to monitor the serial port for incoming data, create a separate
thread for handling the port and use the blocking Read methods.
Remember not to use the port outside the thread that has created it.
Please note that MSDN
Hi,
I'm a little scared that you all want to fiddle with SerialPort
implementation. The Win32 and Linux versions work well and are
reasonably stable (there are some little fixes waiting in svn for
inclusion in next mono release - but you have very little chance of
actually bumping into the bugs
I have the same problem.
I compile the code located at
http://www.mono-project.com/HowToSystemIOPorts.
When I run it I get this:
Unhandled Exception: System.TimeoutException: The operation has timed-out.
at System.IO.Ports.SerialPortStream.Read (System.Byte[] buffer, Int32
offset, Int32 count)

Hi,
I hope to have our OSX implementation up in the next couple of days.
This implementation should work under linux too!!
I am also looking at the serial.c source and will try to get that to
work under OSX as well.
I will send the link ASAP.

Thanks,

Hi,
We could turn this into a new implementation. The serial port is a
major component robotics.
The issue with our code is that we call the Mono posix libraries,
this is not cross platform.
Is this a problem ? If not we can work on the new serial port
implementation.
In any case
Shawn,
I don't know whether it's helpful, but the RXTX implementation of the
JavaComm API is available on a huge range of platforms - and it runs
under Mono after IKVMC'ing it.
Since the portability of the native code is your issue you may want to
take a look at what they have. The .NET
Hello,
The issue with our code is that we call the Mono posix libraries, this
is not cross platform.
Our implementation uses the Win32 api in windows and posix calls with a C
helper layer in Unix platforms.
Observe that we never tested it with Mac.
Since you are using the Mono.Posix
Thanks.,
I will look in to it and see if we can fix the osx version. Most
likely it is a tty setting that has not been set, in OSX Unix there
are a couple of settings that need to be set or the port does not work.

Ok, it will be really useeful for us because we are working on porting
our program to OSX without success.
Please, let me know when you publish it
Thanks

We also have problems with the serial port under OSX. We had to re-

Can you actually get any data out of the port ?

It looks like you are trying to open serial port in the main thread,

Hi Arek,
That's the whole .cs file I have.
I know it looks strange but under mono, the data received event is not
working. That's why I create another thread to do data polling. Maybe you
have better ways to do that?
Thanks

Try creating the SerialPort in the same Thread that uses it afterwards.

So you must verify that the user starts the application is registered in

To find out the group owner of the device by a shell run the command

That's likely because 'mono test.exe' actually uses mono, and
'test.exe' runs .net instead.
This appears to be a bug.
Please fill a bug report with the attached repro.
