I have a DOS based program that I want to run in XP. Now the problem
is not that it wont start, or run in XP. It will, I have in fact seen
it. I formatted and installed 4 new computers with XP Pro. I
installed the DOS program onto the computer. On EVERY one of the
computers, when I open the program it gives me an error "system cannot
open com1 requested by the application" (some say com2, etc) My
current COM port is not 1, but when I try to change it to COM1 and
open the program, the program now says "system cannot open com2
requested by the application". Does anyone have any suggestions? I
cannot find any config file where it would be requesting any specific
COM port, but this might be a function or error with XP.

Thank you in advance,

My experience is that COM ports and XP do not play nice with the "command
prompt" (It's not DOS any more, it just seem like it) window (or full screen).

I put one of those RS232 signal light boxes in the line.
I would set the port speed configuration (as it worked in W9x and DOS).
The lights would *momentarily* indicate the port ready and then go back to not
ready.
Even changing the (Zebra label) printer to 2400 baud (the port default, would
not work).

I keep W98(Se) around just for these old programs.
Good luck
