Hello All,
Well, it worked!
Used:
-The bottom port (not the top port for the admin program)
-Used the same cable (null modem I believe) as for the admin program
-Removed the jumper on J4 behind LED3
-Hyperterminal at 9600 n81 no flow control
-Ctl-C during startup
-Ran c:\sat\killtime to deal with what I assume is a watchdog timer
Works great - back to the glory days of DOS and 9600 baud
Thanks again, everybody, for all your help!
