Michael,

Are you running a DOS executable?

I regularly run a DOS executable to directly interface (set baud/control word/interrupts) to COM:1,2,3,or 4 running on WIN2K. The virtualization works well and is fast enough to a handle 56Kb modem link and read/write multiple files.

I have icon's on the desktop that call batch files which change to the required directory, title the window, and execute the program.

in the properties of the icon i set the "target" as follows:

%windir%System32cmd.exe /k C:amtm.bat

This starts a "console" (i.e. command interpreter) for the batch file. Perhaps this may help.

regards,
p
