[ct-user] CT9.xx pin out?

Jamie, Thanks much for the information which confirmed my memory.
I have reverted to using V8.xx rather than have to assemble another LPT cable. 

I think it's time I explore something other than CT for contesting possibly TR
or get used to my Logic software. I've never gotten a response from anyone
listed as a CT rep nor the BBS so customer service is not a consideration. 

I would rather have seen LTP2 and LPT1 left alone and additional control signals
needed for the antenna switches, etc.. relegated to LPT3/4. I had not yet found
that my W9XT board would suffer as well.

Thanks again for the help.
