Right.  So far I haven't seen any place in PDP11GUI to set anything 
other than port and baud rate, so I'm not sure what exactly its using 
for configuration on that end.  I'll try 8N2 on the DL11 side as see 
what happens.  My DL11 is 7E1 right now and the M9301 emulator works to 
my VT52, but I haven't had any luck yet getting PDP11GUI or a terminal 
emulator on my laptop to talk to it.

I'm finding it somewhat ironic that I managed the entire 11/45 CPU and 
memory system debug without too much difficulty, and now I've been stuck 
on the damn RS-232 link for over a day :-)  Time to give up and scope it 
I guess...
