I need help connecting a Penril ACU to a AT&T 6300+.
The ACU works fine for processes that use getty (like ct),
but does not work for processes that use uugetty (like cu).

When I try to use cu the response is DEVICE LOCKED.  I loooked
at files Device and Dialers.  Those files appear correct. (I
compared them against a Penril ACU defined on a 3B2.)

Called Customer Support and they said check the cable between
the 6300 and the ACU.  I did and did not spot anything obvious.
The cable is wired like the following:

	6300+			Penril
	Pin	  to		Pin
	1			1
	2			2
	3			3
	6			6
	7			7
	8			8
	20			20
	22			22

The above wiring worked fine on the 3B2, but does not on the
6300+.  As soon as the CU command is invoked, I get a DEVICE
LOCKED response.  Note, there are no entries in the /usr/spool/locks
directory when this happens.  The response appears to be generated
by what the 8250 chip is seeing on a status? lead.

I would sure appreciate any help I can get.
