I am attempting to establish a SLIP connection between a FreeBSD box
at home and a campus machine, by dialing in to a local net provider,
telnetting to campus, and then initiating SLIP on both ends, etc..

First of all.. can you see any obvious problems with this?  Can such a link
be established via a telnet session?  Do telnet escape chars need to be unset?
What about shell escapes?

Anyway, the campus end was set up by a friend who is using Linux (successfully)
to SLIP in..   and my end is set up in a standard manner (or so I think):

slattach sl0 -a -s 38400 -r /dev/null /dev/sio01
ifconfig inet 128.32.138.14 128.32.138.2 netmask 255.255.255.0 up
route add default 128.32.138.2

and the /etc/hosts entries are there, etc..

Now, when I try to ping from the BSD to its SLIP provider, it doesn't work - 
I can see the packets being sent by the modem, yet nothing comes in return.
Similarly, telnet-ing to the host or any machine in the /etc/hosts produces
a 'Trying..' message and an eventual timeout.

I connect to the provider by using tip, and suspend tip right after initiating
sliplogin on the campus end, and then I run the 3 commands above.

This is my first time trying to set up SLIP..  and I've no idea what's wrong.

Any suggestions are much appreciated.
