It's been too long since I ran a pure DOS setup, and I don't recall
details.  But I was running MS/PC DOS since the 2.X days, and I don't
recall this ever being a problem.

MODE COM BAUD=19 *doesn't* set the baud rate to 19.2kb?

If MSDOS 7.1's mode command won't let you set a baud rate beyond 9600,
don't use it.  Copy over the FreeDOS mode command, and use it instead.
I know no reason why it shouldn't work.

I'd also use XCOPY or a variant, but that's another matter.

Sorry, but all of this is NOT correct. Once again, nothing in DOS limits 
how high you set the UART speed, and certainly nothing in Windows.

I have been using serial devices (not USB) with 115k baud for decades, 
likewise transferred non-text files over serial connections for that 
long as well, even using such antic dinosaurs like Kermit to transfer 
programs (executables) as well as graphics between MS-DOS and other 
systems like Unix SysV or Atari 520, because I had only BBS access (this 
was before there was what today is called an "Internet") on my MS-DOS 
(later Windows 3.11) system.
At work back in the late '80s/early'90s (CAD software company) we were 
running serial connected plotters at 56K and 115k baud, pretty much all 
of our digitizer tablets ran at 38.4k baud. And I had one of the first 
modems running at 56K baud when the standard was still 28.8K or 33.6K. 
All in DOS...

If you set the baud rate with the FreeDOS mode command, on any DOS, a 
copy command will work, however, there is no handshake, no error 
correction, so you need to have a 100% working serial connection to have 
that working.  A copy to COM[1,2] otherwise will work at whatever the 
speed of the UART is set to.

The copy command is limited to what you set the mode command to.
FREEDOS lets you set the baud very high but other dos's and
even windows has 9600 baud as the upper limit, well below
the uarts top speed. 
If I type copy filename.prn com1: in any other dos besides FREEDOS
its top transmission speed is 9600. Any graphics file would take a few
minutes at that speed. Text file are ok at 9600 but pictures take
forever.
Terminal software like xtalk only send text files at high speeds.
For photos you need the dos copy command.

Again, no DOS is limiting the capabilities of the UART, I don't have a 
working setup anymore since my last move, but I doubt that any DOS mode 
command is limited to just 9600 baud. And if push comes to shove, just 
use any terminal program to set the UART to a higher speed. Or use the 
FreeDOS mode command, it's the tool that would be limitation, not any 
form of DOS...

Just did only a very quick Google search and M$ themself list that least 
an option to set the baud rate to 19200 baud (speed parameter "19").

Its not only MSdos 7.1 but other dos's that limit the uart speed
to 9600 baud. The mode command doesn't go higher than 9600 baud.
I use the dos copy command to send the .prn files to a bluetooth printer.
At 9600 baud you can take a nice long coffee break while it prints.
FREEDOS doesn't have a limit like that. What is the point of making
fast uarts if the software holds you back.

No, it doesn't. I used in fact a Windows 98SE machine booting without 
GUI for years at a environmental project where we got sensor data via 
115200 baud.

Well, DOS does not inhibit the capabilities of any UART. The serial port 
might be by default be initialized at 9600 baud, but there is no reason 
that any application using any serial port can set it to any parameter 
the UART is in fact capable of...

After all, there is no MS-DOS 7.1, it is in fact Windows 98.

But with just a somewhat hazy problem description, it is hard to tell 
what might be amiss here...

Re: [Freedos-user] FDI Preview 15, Update 3

2016-04-23 Thread Jerome E. Shidel Jr.

Freezing: I have Good news and Bad news.

First the Good news,

While running down this issue, I made a little streaming in FDI moving the
MEDIA detection routings out of STAGE700 (The prompting questions STAGE)
into STAGE600 (was unused as reserved). Makes it a little easier to follow
what is going on if reading through the batch sources.

Second, this led me to creating a CD iso version. So, I could run down the 
issue without saying hey Mateusz try this. now this. now this. now this…... 

Third, I was able to pinpoint exactly when the freeze occurred. It was
happening when checking for a files existence on the CD media. This 
led me to find a completely unrelated bug in vfdutil that would occur
if bad command line parameters were given to vfdutil. 

Also, this issue only occurred in VirtualBox when booting the CD. This
does not occur in VMware. It does not occur when using the USB versions
in either virtual machine. I did not test the CD version with QEMU. 

Finally, after spending a couple hours tracking down the exact problem, the 
issue
is not a bug in FDI or V8Power Tools. The problem occurs even when FDI is not 
run
and if no V8Power Tools are ever used.

Now the bad News,

I don’t know where the bug is located. It could be VirtualBox, FreeDOS kernel, 
FreeCOM shell, Himemx, UDVD2, SHSUCDX or possibly the boot disk configuration. 
(Note: removing LBACACHE had no effect on the bug.) 

This does not just effect FDI it effects other programs as well. For example,
the FreeDOS EDIT program. (Boot ALL_CD image, change to CD drive. Run edit. 
System Lockup)

A couple easy tests to replicate issue.

Create a VM in VirtualBox (with a Hard Drive, other settings like RAM 
are unimportant)

Boot the ALL_CD.iso. 
http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.1/repos/all_cd.iso

Select Language in FDI, then exit to DOS.

Change to CD drive. (Should be D:)

Run any of the following:

edit(immediate freeze)

vfdutil /u D:\test   (in a stripped down config, it will 
run once without a lockup)

In summary, 

As best as I could determine, this bug occurs when reading the directories on 
the
CD ROM. Possibly a FindFirst/Next issue. Once i ruled out FDI and V8, I stopped
tracking down the issue.

Unless the non-FDI issue is resolved, the CD iso will not be able to install 
FreeDOS 
under VirtualBox. VirtualBox will only be able to use the USB images.

I also tested a completely stripped down startup config that only loaded 
HIMEMX, 
COMMAND, UDVD2, SHSUCDX and did not load FDI or any V8Power Tool. The 
problem still existed.

There may be a VirtualBox specific setting or switch needed for one of those 
programs that I don’t know. If not then it is a bug. 

Thanks, Jerome

Your the one who pointed me to MSdos 7.1.
I've noticed a few annoying short coming
for msdos7.1 that FREEDOS doesn't have.
1st it limits the rs232 output to 9600 baud.
Most URATs can go to 115000 which is what I often use.
I use rs232 to print bluetooth from dos.
9600 baud is crawl speed
The other is when I tried to install a sound driver
on my laptop. MSdos7.1 insists that I use windows
to install it so that I can enjoy the windows/dos enperience.
FREEDOS just installs it, no arguments from it.
Other than that MSdos7.1 is very nice.
