[Qemu-devel] Access to serial port, guest> DOS | host >WinXP

Hi,

 I have a sensor that sends frequency modulated data to the 
serial port. These data are processed by an old  program 
running under DOS. This works well up to Win98 (starting the 
software from command line) but from Win2k on it does not 
work any more. 

So far I have tried VMware, VirtualPC, and DOSBox. All 
emulate the serial port but the data read in are unreliable or 
simply wrong most probably due to timing problems at the com 
port (I am far from being an expert).

 I now tried QUEMU (host: WinXP, guest: DOS). But I even do 
not receive any data. Does anybody know a solution? If I were 
able to at least accessing the serial port I could find out 
whether the data are read in correctly. Or is there no chance 
that this setup will ever work?

Thanks for hints, Dieter

Thanks a lot for these hints! I'll try as soon as I get linux up and running. 
Badly enough I do not have much experience with this OS.
regards, Dieter

Dieter, believe it or not, but I had very good results with dos programs 
accessing serial ports with Wine (Way better than $VMWARE).
If you get Runtime error 200 it is a C run-time error that can be fixed, which 
was all I had to do.
I used SuSE-8 at the time. I personally dont really like wine, but it does the 
job with some Dos programs better than the expense of Vmware.
I still run some very tricky dos programs that way. Doing it all on Qemu 
would be WAY nicer.
I am currently also looking at Qemu for better port access in general or to 
develop myself what is lacking to access ports.
If you want to try the wine option let me know and I can walk you through it.
You can contact me off-list at my email-address.

Have you tried Wine? Maybe it works for you even the application is a DOS 
one.
