You don't find a /dev/tty00 or /dev/tty01?  If not then clearly you
won't be able to access the serial ports.  Take a look at the file
/dev/MAKEDEV.  This is the main script that drives the creation of the
device special files.  You can simply cd /dev and do something like the
following:

	sh ./MAKEDEV tty00

I have to confess it's been a while since i did tty00 so if you take a 
quick look at this script you should see the section for creating tty*
type devices.  Follow the instructions at that point.

Oh yea, if you haven't realize this yet:

	COM1 ==> /dev/tty00
	COM2 ==> /dev/tty01

It isn't in so much as failure to have these files will do this.  However,
they are always created when the system gets installed.  So, I'm a bit 
baffled as to why you don't have them.

In your case I guess the answer is yes... via the MAKEDEV script.

Yea, CD-ROM's are in 9660 format not UFS filesystems.  You need to 
mount this using either:

	V1.1.5.1:

		mount -t isofs /dev/cd0a /cdrom

	V2.0+:

		mount -t cd9660 /dev/cd0a /cdrom

Have fun,
