Looking for TCP/IP PC networking

[Adam Carlson]

Does anyone know of a good networking system that will allow me to
connect my MS-DOS PC's to my Sun 3/80's (running SunOS 4.1) other than
Sun's own PC-NFS.  In particular, there is a notice on the Sun
literature that indicates Locus Computing's PC-Interface and MIT's
PC-IP.  Does anyone out there know anything about these (or other
networking) products that would fit this setup.

If it is useful, I have 3-4 on-site PC's and 2 Sun's, I would like
peer-peer capabilities on the PC's but it is not a priority (Sun's
PC-NFS doesn't do it).  I would also like to allow access from a number
of off site locations, through modem connections.  Again this is not a
necessity.  Finally, my on-site PC's are already connected to an
ethernet through a terminal server which they get to via their serial
ports.  If possible, I would like to avoid the expense of ethernet
boards on every PC.

What I need to be able to do at a minimum is: store data files and
programs on the Sun and access them from the PC's (the programs should
be runnable by more than one PC simultaneously), print to lpt?: on the
PC and have it rerouted to the Sun for placement on the Sun's print
queues.  Remote backup of the PC onto either the Sun's tape backup unit
(preferably) or disk drive (if that's the only way).
