>Description:

	/dev/dty?? devices, via puc, do not work properly with 'cu'

	We've installed a Lava Computers DSerial PCI serial ports card
	for use with a modem for UUCP.  Since this system is new enough
	to support /dev/dty?? dial-out devices, I tried them but found
	the change of carrier when the CONNECT message was issued
	triggered a SIGHUP!  (I.e. presumably with a transition of DCD
	from off to on!)

		puc0 at pci0 dev 8 function 0: Lava Computers serial port (com)
		com3 at puc0 port 0: interrupting at irq 9
		com3: ns16550a, working fifo
		puc1 at pci0 dev 8 function 1: Lava Computers serial port (com)
		com4 at puc1 port 0: interrupting at irq 9
		com4: ns16550a, working fifo

	I'm guessing this is a bug in 'cu', though I mention the kernel
	and driver information in case it's relevant.  (Should SIGHUP
	really be sent on trasition of DCD from off to on!?!?!?)
