The scanner is not the problem, since you got it to work under Windows 98, with
a normal serial cable arrangement.

Sometimes there can be conflicts (comm settings or drivers, for instance) when
you use a serial-to-USB converter ... as you did with the computer running
Windows XP.

There can also be conflicts if something else is sharing the same port, such as
a modem, mouse, PDA, etc.

You might want to check the comm port settings on the two computers - atleast
for the ports you used in your test - and look at how the settings on the XP
compare to the Windows 98 PC.

If you are using Win92, consider contacting Don Starr for advice, and check for
any ".ini" files related to the comm port in the program.

I would also try borrowing a different make of serial-to-USB converter from
someone, and trying that out. The difficulties that the converters can add to
the equation are enough that some software writers - notably Butel (ARC 780 and
ARC 250) - don't offer technical support for their programs when the converters
are used.
