	This is pretty slow - you ought to be getting
	more like 1000-1300 cps or more.

	You definitely need no flow control with uucp
	if you don't ask the modem to perform baud
	rate conversion (set S66=0, that is). Also
	you should make sure that UUCP spoofing is on
	(S111=30), Data Compression off (S110=0).

	There are serious serial driver problems with
	CTIX before release 5.0; perhaps an O/S upgrade
	in the near future might be helpful.
