Keywords: error ports 3b2 ACU

The ports on the I/O boards seem to be unsuitable for running ACU's as
well.  I have a penril auto dial auto answer smart modem hooked up to
the contty port and it works fine, but when i tried (and am still
trying) to add a second ACU to tty11, all kinds of strange things
happen.  I'm trying to use uugetty and in bidirectional mode.  It
sometimes works for a very short period, where uugetty is spawned on
both lines, but not always.  Many times when i boot up the system, the
the console gets flooded with the error messages:
	Pump Error: 14 - ioctl call
	getty: cannot open "tty11", errno: 6
When the boot is successful, after the first time the ACU on tty11 is
used, the uugetty process is no longer associated with any tty (seem
with ps -elf) and just shows a ?, and no processes are ever active on
that line again until the next boot.  It is a 3b2/300 running SVR2
(from the factory) with 2 Meg of RAM.  Any ideas or can anyone shed
some light (or suggest possible workarounds) on this?
