The actual device names should be /dev/ttts* ... although if you have a 
version of the driver that has 9-bit support you will also see /dev/tt8s* 
(this is a typo in the source, it really should be tt9s for 9-bit).  If you 
don't see all 10 ports (0-9) or if you have difficulties accessing some of 
the port you will want to make sure you have the latest drivers 
installed(ftp://ftp.embeddedARM.com/tsuart-2.6/).  Depending on whether you 
are using mdev or udev or manual mknod'ing the actual device files *could* 
be different.  If you use mknod the TS-7800 TS-UARTs use device major 234, 
device minor 65 to 75.

That should be all you need... but note that the default termios set up of 
your ports may be different from a Linux PC or even another ARM UART. 
ftp://ftp.embeddedARM.com/tmp/term.c has a sample function I've had good 
results with in setting up a serial port in C.  Some additional information 
on TS-7800 specifics of these uarts can be found here:
