I have an extra serial port (9-pin), and I was looking for a 9-pin to
25-pin cable. That was when I ran across these serial to USB cables
which looked pretty cool, especially since I have extra USB ports.
(Henry, I'll take you up on your offer for the cable. Let me know when
and where to get it...)
A followup question: Since the 25-pin SP connection is the same as the
PP connection, can I hook my PP ZIP drive to the SP, and my SP modem to
the PP? When is a serial port not a parallel port, and vice versa?
I've got the ZIP drive-to-printer hookup on my parallel port, and want
to use my scanner as well, but I understand that daisy-chaining these
things slows down performance. If I expand my port selection with
another card, do I need to get a PP card for PP devices, and SP for SP
devices? (I mean, if the shoe fits...) ;) I just want to understand a
little more 'bout the hardware.
Thanks to all who helped...
