We are attempting to run some 16-bit software which ran nicely under

Subsystem, "Driver doesn't support baud rate (9600). Close Ignore" We've
tried several baud rates with the same result. Each time we configured the
com1 port in Device Manager for the intended baud rate.
My guess is that your application is programmed to access I/O
registers directly, and not through Windows' API calls, as it should.
Windows 98 allows such direct hardware access, but XP does not.
The obvious solution is, of course, to upgrade the software to proper
32-bit design, but that may not be a possibility for you?
You might try to install '98 on a virtual machine and see if VMware's
hardware emulation can handle your situation.
