: You can use UUCP over TCP.  You still benefit from the well-settled

Ahh, but at the moment (until tomorrow, but maybe again soon), I'm
connected as a laptop->workTCP->workmodem->homemodem <break> homemodem->ISP
type connection....  The problem is with getting news/mail to go from my
(FreeBSD) laptop, across the work network, through the work modem
(who's machine doesn't support either SLIP or PPP) and onto my home
(FreeBSD) machine (once it's there the rest is easy).  I need to have a
network-type (socket) descriptor that I can condition as SLIP/PPP.  If
this were possible (even though it's not actually a serial descriptor),
I could tunnel from my laptop across the network, through a connected
serial link and talk to a regular ppp on my home machine.

Maybe the correct way is to implement a device that pretents to be a
serial device, but is a network connection - you make the connection
using ioctls, but you can also do *anything* serial...  a lot of it
just wouldn't actually do anything
