Good evening,
a way to ask this question better then.

That depends on the OS. I have a ThinkPad, with 3 USB ports. With
Linux, it doesn't matter which port I use, the adapter gets the same

specific adapter.�
Would that number go up, say to USB1 to simulate com 1? For example
there are dectalk USB devices, however for the software to find the
item a port would need to be associated in Linux or likely in a
virtual setting as well.
I assume it would. However, I only have one adapter to try it with.
� On the
same computer, with Windows 10, the com port number depends on which
USB port the adapter is plugged into.
Is that com port number determined in the Bios or by windows? By
which I mean is it software determined or hardware determined?
Is the BIOS still used for that sort of thing? I got the impression
they gave up on it years ago, as it was so inadequate.
I have never used any USB device with Freedos or
any other DOS.
That is unfortunate. granted I cannot speak to freedos as my
machines seem to be too fast for the system. still in ms DOS 7.1
the one I am using now, I have an amazing
DOS USB driver that was written by Panasonic. Lets me use my
external USB drive for backup among other things.
Thanks for the explanation,
I have an OpenDOS 7.01 CD here, which I came across the other day, but
haven't done anything with it. After I left IBM, 20 years ago, I had
both PC-DOS 7 and PC-DOS 2000 (Y2K version of PC-DOS 7) on floppies,
which I tossed years ago. However, it's been many years since I did
anything with DOS.
