You are correct about the eight-packets-in-flight limit in `g' protocol.

The right thing to do is write your own protocol module for uucico,
which better fits the link layer you're using.  There is precedent:

protocol	organization	link layer
--------	------------	----------
  t		CSS (seismo)	TCP/IP
  f		CWI (mcvax)	X.25 (standard with PAD)
  x		AT&T		X.25 with VPM

You say that your satellite connection is error corrected; is it also
flow controlled? If so, the `t' protocol is probably what you want.
It's a waste to run `g' protocol over an error corrected link anyway
because the effort that `g' puts into checksumming is wasted.
