Serial ports and mounting disks

[certain at vangogh.cs.unc.edu]

I set up an A/UX system last summer and have pretty much just let in run
since then.  I now have to make some changes and have forgot most of
what I know.  In addition, my support hotline account has, of course,
run out, so.....

I have a Mac/OS program that controls the serial ports in what is probably
a low-level way.  The product is called Teleflex and it is a voice-mail
machine for your Mac.  When I run it, it says "checking hardware connections"
and then stalls.  I assume it's trying to access the hardware unit
connected through the serial ports, and A/UX won't let it.  Any ideas?

The other question which probably has an obvious answer is how do you
mount a disk in single-user mode?

Thanks for any help,
