You probably will want to use System V.3 STREAMS.  AT&T sells two books,
a STREAMS Primer and a STREAMS Manual which contains much of what you
need to know.  The Primer is overpriced and is largely a subset of what is
in the Manual, but when I remember reading both a few years ago, it
felt like there was some stuff in the Primer which was missing in
the manual.  I can't say for certain right now.

A STREAMS device driver is fairly straightforward once you grok the
way the entire design works.  It's always helpful to have boilerplate to
copy from, of course, but you can probably do a fair job on your own.
