*I*'m working on it. Right now, the beast runs under Apple's A/UX, a Sys5R2
system with almost, but not quite, all BSD 4.3 and Sys5R3 stuff.
I'm currently porting my whole ISDN subsystem to some PCish Unixes and Linux
is a great base because I actually have sources to the kernel, especially
the Streams subsystem. (I know that Linux doesn't _have_ a Streams subsystem
yet, but Fred van Kempen is working on one. As an interim step, I might
just hack up my own.)
This system features neat stuff like Streams derivers for SLIP framing,
HDLC framing (as used by PPP -- PPP itself isn't implemented yet, but
it will happen eventually), stuff to log traffic, and of course basic
access to "dumb" and (eventually) "intelligent" ISDN cards.
One of the not-so-trivial problems are that every country has its own
special ISDN standard, which in many but not all cases is almost, but not
quite, unlike the Q.931 standard that the CCITT intended to be used for
ISDN access. :-(
