Using the ttyb serial port on a V240
I am trying to connect a terminal to a V240 via the ttyb (10101) port, the port directly above the "Serial Mgmt" port.
I added the following line to the /etc/inittab file:
c1:234:respawn:/usr/lib/saf/ttymon -g -h -p "`uname -n` login: " -T sun -d /dev/ttyb -l console -m ldterm,ttcompat
The ttymon process showed up soon afterward:
unixsrv3# ps -ef | grep ttymon
root 26551 0 12:34:31 term/b0:00 /usr/lib/saf/ttymon -g -h -p unixsrv3 login: -T sun -d /dev/ttyb -l console -m
and pmadm shows the port monitor:
unixsrv3# pmadm -l
PMTAG PMTYPE SVCTAG FLGS ID<PMSPECIFIC>
zsmon ttymon ttyauroot/dev/term/a I - /usr/bin/login - 9600 ldterm,ttcompat ttya login: - tvi925 y #
zsmon ttymon ttyburoot/dev/term/b I - /usr/bin/login - 9600 ldterm,ttcompat ttyb login: - tvi925 y #
But when I connect either a dumb terminal or a PC based terminal emulator to the port, I get nothing... no login prompt. Dead silence. I tried both straight through and null modem cables, and neither worked. The null modem cable worked fine on the SerialMGMT port (ttya).
Any help is greatly appreciated!
