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

[Dieter Blaas]

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
