A few of us have bought 7300 in the last couple weeks and we don't seem to be
able to connect a terminal to it.  Before we loaded 3.5, the 'Hardware Setup'
option from Install asked for the terminal type and the terminal came up just
fine.  After we installed 3.5 and all the system software, the 'Hardware
Setup' form no longer asks for the terminal type and the terminal will not
respond.

We tried reading the line with a 'stty' call and couldn't read the line 
with 3.5 and a program can't read or write to the line either.  Both the
'stty' call and the program ran fine on the system configured with 3.0.

We are trying the connection with a null modem on the RS232 port connected to
a tvi950 terminal.

Has anyone successfully direct-connected a terminal to a 7300 running SYS5
V3.5?  If so any response would be greatly appreciated.
