How do you know?

You're leaving too much to chance. Try specifying everything:
set modem type none
set carrier-watch off
set line \m(ttyport)
if fail exit 1 Can't assign \m(ttyport)
set speed 9600
do vax ; (which implies SET FLOW XON/XOFF)
Now at this point, instead of entering server mode, give a CONNECT
command. Ditto at the other end. Now everything you type on the VAX
should show up on the AIX screen and vice versa. If not, you have a
fundamental communication problem: wrong port, bad cable (is it a null-
modem cable?), flow-control mismatch, speed mismatch, etc etc.
The C-Kermit manual has a chapter on how to set up and check a direct
serial connection between two computers; follow the directions there.
