Mods to 4.2BSD UUCP for VENTEL modem registers

Hi,
	The diffs to the 4.2BSD UUCP file condevs.c allow the usage of
a Ventel 212's phone number registers and linking capabilities. In particular,
the Ventel can be directed to try a number over again if it gets a BUSY, or
to try a different phone number.
	The additional L.sys syntax support is:

	if the phone number spec begins with '$', then
		1) do not send 'K' to begin dialing,
		2) do not send a terminating \r after the phone number spec
	if a '|' occurs in the phone number spec, sleep(1),
	if a '$' occurs after the first char in the phone number spec, then
		send a \r

	Thus if the phone number is 123-4567, (experiment with the '|''s)

		$S1|1234567%L1|1

	will cause the Ventel to store the number in register 1, including the
	link of register 1 to register 1, and to dial register 1. Then if the
	number is "BUSY" or "NO ANSWER", etc, the number will be redialed
	(until uucico timeouts).

		$S2|1234567%L2|K|9876543L2

	will store a number in register 2 with a link to itself and dial
	another number, which if BUSY, will dial register 2.


	My experience is that a number which is BUSY is many times not BUSY
the second time it is dialed by the Ventel, i.e. redialing is often helpful.
	BTW, the Ventel has 5 registers.
	If you didn't want to hack UUCICO, the above scheme might work if you
hand loaded the registers and included a link in the phone number spec. The
old code, however, insists on terminating the phone number with a \r, which
often ABORTs the dialing.
