"Sh*t happens."  Live with it.

There is absolutely *zero* difference between a serial port using a null
modem and a RS-232 interface modem on that same serial port, as far as
the operating system is concerned.

I've tried to tell you what *will* work, and how to find appropriate hardware,
and all you want to do is argue with the help you're being given.

What you need to do is hire somebody to *do*the*programming* to port the
device driver you "require' to the newer version of the O/S.
