No chance. You should rework your code for A/UX to use more
conventional UNIX techniques namely opening /dev/printer or
/dev/modem (otherwise known as /dev/tty0 and /dev/tyy1) and
using ioctl calls to set baud rate etcetera. You'll hate it but
A/UX is never going to let you see the hardware. A more
Macintosh solution is to rewrite your Mac stuff for the Comms
Toolbox and hope that A/UX gets Comms Toolbox emulation (though
without your support contract you probably won't get such a new
version...).

Easy. Type the commands

        pname -a
        mount -at 5.2

to get all of the normal filesystems mounted (except NFS ones,
but you'd need to do various other things to get your machine
ready for those). A cautious person would probably run fsck
before the second command to make sure the filesystems were OK,
but isn't life boring if we never take chances...

No problem, other than the fact that about 1/3rd of the
messages that I see on this group actually come from me or my
colleagues! Is there a lot of stuff over in the US that doesn't
make it across the Pond, or does nobody read this group?
