The mapping of ports is show here:
http://www.embeddedarm.com/about/resource.php?item=303#uart
For Linux 2.6 TS-UARTs are typically at something like /dev/ttts*.
(Unfortunately the initial versions of the driver weren't consistent on
this due to typos in the source code so if you don't have the most
current driver you may have to search the /dev directory for a name that
starts with "tt" and has "t" and "s" following that.)
