I tried it. I typed,

	# cu -l cuaa4
	Connected.

After this I notice that the modem does not go off hook. And further 
more, when I tried to type AT, I don't see anything displayed on the 
screen. I know it's supposed to show 'AT' as I typed it.

I thought maybe I referenced the wrong port, so I tried it all from cuaa5 
to cuaab but I got same results.

I hope this piece of info helped.

Any other test you could recommend?
