This should have made it work.
The method for directly connecting two computers back to back is
documented in detail in all three Kermit books, including diagrams, etc.
The most common mistake, for me at least, is mistaking a gender changer
for a null modem or vice versa -- many of mine are not labeled. Another
common mistake is mistaking a modem cable for a terminal cable, but you
already checked for that.
Assuming your hookup is physically correct, I can only guess that you did
not give the right sequence commands to C-Kermit. You should have given
the following commands in exactly this order, as documented in "Using
C-Kermit":
set modem none
set line /dev/ttya
set speed 9600
set flow rts/cts
set duplex half ; You need local echo for "chat" connections.
set term newline on ; You also need this for chatting.
connect
Finally, if you want to log in on your Sun from the PC, then you have
to enable logins on the Sun port. See your Sun documentation for how to
do this.
If you have any further trouble, send email direct to kermit@columbia.edu.
