I have installed them into the box and lspci see's them but there are no tty's in /dev. I understand that I need to create the tty's and set them up with information which I think I have got using a few other commands. I just need a good how-to to hold my hand through it.

I thought Mandrake used devfs in  9.1, so the nodes should be create for 
you; they just wouldn't be called ttyS[0-9], they would be tts/[0-9].

First you need to find out where the modems are
$dmesg |grep tty
ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS04 at port 0x6800 (irq = 9) is a 16550A

This shows my fax server, the first is the onboard serial port, the 
second is my modem.  If you do
$lspci -v
[..snip..]
00:0a.0 Communication controller: Lucent Microelectronics Venus Modem 
(V90, 56KFlex)
       Subsystem: Lucent Microelectronics: Unknown device 5656
       Flags: bus master, medium devsel, latency 0, IRQ 9
       Memory at e8001000 (32-bit, non-prefetchable) [size=256]
       I/O ports at 6800 [size=256]
[..snip..]

You'll notice the 6800 in common.  Now if I had devfs I'd find my modem 
at /dev/tts/4 (see thettyS04).  You would want to create a symlink 
between /dev/ttyS4 and /dev/tts/4, hylafax doesn't like  subdirectories 
in  dev.  If you're not using devfs then you'll need to create 
/dev/ttyS4 with makedev `cd /dev; ./MAKEDEV ttyS4`.  You then want to 
chown/chmod ttyS4 to the correct permissions, I use uucp/600.  Then you 
can use `cu -l /dev/ttyS4` to test the modem.
