Serial port communication

[eru]

Hi folks

I've been trying to programm some devices which need a serial port win-app http://a-m-c.com/download/software/amcds3-7-6.zip but can't get it to work :S

wine can run it without problem until the serial port is activated. I read about making the link to the port and I created on "dosdevices" folder.

I'm not sure what's the next step, does anyone have an idea?

thanks in advance

Assuming you have real com devices (not usb):

Code: Select all

ln -s /dev/ttyS0 ~/.wine/dosdevices/com1
ln -s /dev/ttyS1 ~/.wine/dosdevices/com2
ln -s /dev/ttyS2 ~/.wine/dosdevices/com3
ln -s /dev/ttyS3 ~/.wine/dosdevices/com4

Then make sure that all of those /dev/ttyS? "files" are accessible by your user.

yes, I run that command and the user is part of the "dialout" group, it can read the port, already tested with a touchscreen using:

Code: Select all

cat </dev/ttYS0

that gave me some data when the touchscreen is activated

Simple reads and writes to the serial port should succeed, and most of the
contol possibilities that the Win32 API offers should work too. So either
your program uses soemthinhg unusual and not yet implemented, or you setup
doesn't work.

Again WINEDEBUG=+relay and a search where ther error is displayed and what
goes wrong before might get you starting.

well, I se this:

here is the crash:

Snoop channel is unreliable and can cause crashes like that. So don't spend time trying to chase something that's not your problem.

understood..

I already reported as bug, I hope some day can run this software
