Yes, that seems right.

I don't recall linux having slattach, but a simple DIP script will work
nicely:

port xxxxx	# Where xxxxx is replaced with the name of the serial device.
speed 19200	# Obvious enough
get $local 129.0.0.1	# Set our IP address.
get $remote 130.0.0.1	# Set the other end.
default			# Make the route the default-route
mode CSLIP		# Fire up the interface.
# Script ends here.


That should create the necessary CSLIP interface at the linux end.

Aha! Look in /etc/ttytab

root can only log in from terminals which are marked as 'secure'.
BUG: If you are refused login as root, on a non-console tty, then all
further logins on that tty will be refused. No sure where the bug lies. I
think it's in telnetd. But it could be somewhere in mintos.
