Subject:  Telnet/SMTP/Ethernet, Possible?

I would like to send & receive very basic telnet commands with a pic or send per
iodic SMTP messages to my mail server, whichever is easier. I'm wanting to deliv
er temperature readings from a remote location in the mountains down to a contro
l center 90 miles away which has a wireless ethernet link with the site (soon to
 buried in the snow). The only interface available is a standard ethernet hub, e
ither 10Base-2 (coax) or 10Base-T (UTP). Prefer the UTP, and (wishful thinking h
ere) a 16F84. I ass-u-me I will need another devce to make the actual PIC-UTP in
terface, but that only gets me so far. I still need to properly encapsulate the
packets, etc. Asking too much? Tutorials out there? I may just put a cheap-o Lin
ux server up there and read the printer port if this isn't going to happen.

FWIW, I am familiar with SMTP and telnet protocols, and have a pretty good grasp
 of networking issues, but it's always been with off the shelf hardware in PCs o
r other related networking devices.

TIA - Fred
