: HAPPY DAYS AND JUBILATION!!!!!
:
: After discovering that my null modem adapter was incorrectly wired, and
: after trying (TWICE!) to create the proper IIGS high speed modem cable,
: I got a solid connection from PC to GS!!

That is great news.

: Thank you all for your input.  It has been a frustrating yet rewarding
: experience working with these cables.

I'm sure the satisfaction of knowing you are successful is enough
thanks for all of us.  :o)

: For others who want to roll their own cables, I have a couple of
: discoveries:
:
: 1. DB25 male and DB25 female connectors have DIFFERENT pinouts!  The
: pin numbers are in the opposite order so that they can mate correctly.
:
: 2. When building a null modem adapter, in order to get the pins from
: the first DB25 female aligned properly with the pins of the second DB25
: female, BE SURE THEY CROSS OVER! If you wired them straight through,
: chances are one of the DB25's is using the incorrect inputs.

OMG, you're kidding.  LMAO!!!!!!!!

: 3. Most PC modem cables are solid and reliable, and have the correct
: pinouts.  I can't say the same for most Mac or Apple II cables.  It
: seems that most cable manufacturers and custom builders have lost
: interest in Apple serial I/O and are building everything to be USB.

As I tried to state in previous posts, there are so many
different configurations of cables for the Mac/IIgs, and
all look the same, you really have to trust the seller, and
also be aware of model numbers. There are lists of model
numbers on the internet, and you can find out before-hand
whether it is the proper cable.  :o)

Apple II Forever, and Apple II Together,
