Need Help With Wiring from SSC

[tmmadden@umich.edu (Tom Madden)]

Hello Apple II Folks!

I was recently given an Apple IIe, and after a few years I thought that I
would again start dabbling in the World of Apple II. Before I had left my
Apple IIgs (had to move, no room for it, sorry :-) ), I had made images of
all of its disks and stored them on my desktop computer. Now, I want to
blast them all back to real Apple IIe disks. 

So far, I have downloaded ADT 2.22, hooked up a NULL-modem cable and have
sucessfully transfered the executable over to the Apple IIe. It runs and
everything, but it will not send anything to the ADT Server running on my
desktop computer. So, to debug the situation, I shutdown the ADT program,
put the Super Serial Card into dumb terminal mode, and fired up a terminal
program on my desktop machine. What I found was that I could send
charcters from the PC to the Apple IIe and have them display on the IIe's
screen. Unfortunatly, when I tried to send characters from the IIe to the
PC, nothing happened. 

My guess is that there is something wrong with the transmission lines
coming out of the IIe. The 25-pin connector connected to the connector on
the back of the SSC does not appear to be a stock apple-made connector, so
this is suspect. Could someone who has an Apple Super Serial Card
(preferably the "Apple Super Serial Card II') a multimeter, and a few
minutes find out the correct way that the pinouts from the connector on
the back of the SSC are supposed to be wired to the pinouts 25-pin
connector? I could not find this info anywhere in the SSC manual. I would
appreciate it greatly!

Thanks in advance.
