[comp.unix.ultrix] Ports for Telnet service

	I recently set up a telnet service (LAT/Telnet Gateway) thru our
Ultrix 3.0 system (VAX 8650).  We have 128 LAT ports created (256 configured),
so the upper eight LAT devices are /dev/ttyC[0-7].  I thought that I would
allocate the ports for the telnet service to these top 8 ports (rather than
taking 8 out of the middle - LAT printers start at tty00), thus leaving
room to expand downward.

	When I set the telnet service to use ttyC[0-8], it didn't work.
The telnet service was created, but lattelnet wasn't running on any of
the ttyC's.  Connecting to the telnet service resulted in being placed on
ports beginning at tty88, which were running getty and yielded a Login:
prompt.

	Several questions came to mind.  Why wasn't the telnet service
using the ports that were assigned to it?  Why weren't the ttyC's running
lattelnet (they weren't running getty either)?  Why did connections to
the telnet service go to ports starting at tty88?

	I changed the telnet service to use ports starting right after the
LAT printer port assignments and everything is working fine.  The telnet
ports are running lattelnet, and the ttyC's are running getty.  This is
okay I guess, but why can't I do it the other way???
