Subject: Re: UC 1.4

Two problems with UC under 4.2BSD:

	the fstat subroutine needs to be renamed to avoid conflict with
	a system routine by the same name; on 4.2BSD it causes recursion
	until the stack blows out of memory whenever you use printf
	(like first thing in the banner line!)

	The timeouts used in getting a byte from the modem don't work in
	4.2BSD.  Either a select(2) call must be used or longjump.
	(Reason: in 4.2, an alarm signal received during a read will be
	processed and then the read is requeued.  Thus the alarm to kill
	the read and return TIMEOUT never returns until a character is
	received.  [Don't ASK how long it took to figure that one out!]
