Basically what I was thinking, but you could put minicom into either
/etc/passwd for a special 'pabx' user-id, (instead of /bin/*sh). Or at
least have it run automatically from the .login or .profile script
for that "pabx" user-id if it started up one of the more common
bin/*sh programs.

The second way is probably better because the /bin/*sh would first work
out the terminal type & size of the inbound telnet session.  i.e. vt100,
vt220, xterm, 24x80, etc. To call minicom, I'd use an 'exec
/path/to/minicom'
as this will cause the 'minicom' process to replace the /bin/*sh
process, and
the user exits minicom, there will be no shell to return to for hacking.
