Hmmmmm....Jeff, just a guess...did you try swapping the rd and sd lines between
the Amiga and the Terminal?  That is, the Receive Data and Send Data lines.
This is what I usually try when nothing else works...the term usually used is
"Null Modem" cable.  The Amiga is expecting to see a modem on the other end
of the cable, which has RD on pin 3 and TD on pin 2...to talk to a terminal,
yoyou need to plug the TD on the terminal (pin 2) to the RD on the Amiga (pin
3) and RD on the terminal to TD on the Amiga.  Give it a try....swap pins
two and three on the cable from the terminal to the Amiga.

Good Luck.......Lance (ltf at the Well!)
