The one complication is that the hdlc stuff I'm talking about is
bit-synchronous. So you actually end up sending packets, not just
collections of bytes which make up what the network layer thinks is a
packet. I.E. this hdlc stuff has definite framing. The hardware needs to
be in a mode which is electronically incompatable with asynchronous
tty data (it's kinda like running a point-to-point Token Ring interface
at 57600 baud). That's why I want a seperate driver (somehow).

Take care,
