We're looking at SLIP for connecting remote PC systems with our UNIX boxes
and I've got some questions on implementation:

Setting up the UNIX hosts with sliplogin (from slip4.0) is not a big problem,
but SunOS 4.0.3 doesn't allow it easily from ttytab.  This isn't a big problem
either, but I have a limited number of ports to connect to via slip.  Has
anyone tried to implement sliplogin as part of the cycle on the getty baud
rate cycle?  I was thinking of having sliplogin first, then break for the
different speeds of getty.

On a PC, in this case with an MNP modem (19200/9600/...) running PC/TCP
software, starting up slip, how do I get the modem to dial the proper number?
I also have some special commands and passwords to get through some security
to set up the connection.  Is that possible?  I tried using procomm to
call, then try and connect, but either dropping or not dropping procomm didn't
let slip work.  And none of the PC/TCP utilities work without a connection in
place.  Any ideas?

Is there any way to assign the SLIP IP addresses on the fly for the remote
connections.  We're going to have N PC's and only M connections (M<N) but
not everyone will be calling in at the same time.  I'd rather not have to
have the users know M IP address to try, I'd rather let them establish a
connection and get the IP address of the SLIP login.  Is that possible or
against the protocol?

Is there a better way?  PPP doesn't seem to be fully operational on SunOS
4.0.3 or 4.1* yet, at least not without source license.

Please email and I'll post a summary of the responses.

Thanx
