I've used the SLIP packet driver, but I'm curious about other solutions
to the problem of network extension over serial lines.  Has anyone
worked on implementing PPP under MS-DOS?  Any tips?

Also, does anyone have any ideas on sharing a serial line between IP
and Novell NetWare's IPX protocols?  I have two ideas on this:  (1)
use PPP; (2) Encapsulate IP in IPX.  The first has the disadvantage
of being non-standard, at least for now, and the second would require
a NetWare 3.11 router and two packets sent over the Ethernet for every
one sent to or received from the remote site.  (The modems used must
be attached to a terminal server on the Ethernet.)

A third possibility would be to encapsulate the IPX in IP and to let
a NetWare 3.11 router deencapsulate.  This seems to have all of the
disadvantages of 2, with the additional disadvantage that custom IPX-
in-IP encapsulation for DOS would have to be developed.

Any comments or brilliant ideas?  :-)
