Uucp and uucico can be told to open the port in O_NDELAY mode by
marking the Devices file tty name with ",M":

	ACU	ttyA7,M -  2400    hayes

Then, in the Dialers script you must add \M and \m tokens to
enable/disable CLOCAL mode

	hayes	=,-,	"" \M\dAT\r\c OK\r \EATDT\T\r\c CONNECT \m\c
			   ^^                                   ^^
			enable CLOCAL                      disable CLOCAL

It enables CLOCAL mode for the duration of dialing, and once the
CONNECT is seen (i.e., once carrier is present) CLOCAL is turned
off and a hangup will truly hangup.

This won't solve all the uugetty problems, but it is a big start.

Why not add Hollerith fields to printf?
