I just set up a hardwired connection between a 9000/370 as callee, and a
9000/320 as caller.  Below are my entries for /etc/inittab, /etc/gettydefs,
and the /dev/tty00 special file on the 9000/370.

/etc/inittab:
     tty0:   :respawn:/etc/getty -t 165 tty00 9600
/etc/gettydefs:
     9600# B9600 HUPCL PARENB CS7 # B9600 SANE PARENB CS7 ISTRIP IXON IXOFF -IXANY TAB3 #login: #9600
/dev/tty00:
     crw--w--w-   1 root     guest      1 0x090004 Oct 20 14:41 /dev/tty00

This of course is not an official answer, and the minor number of the device
file is subject to change based on the select code of your interface, and the
actual RS-232C card that you are using, etc., etc., etc.

Hope this helps.  It worked for me.  

BTW, since you can cat files to the terminal, I would assume that the device
file is set up properly.  So, look into your inittab and gettydefs file.
