Peregrine,

Just a warning...Marty Kramer and I have recently found problems in the
HiDEOS Octal UART driver that show up when two or more ports are being
driven(very hard), simultaneously. If your driver has not been tested
under these circumstances it may have inherited these problems.

Let me know if you want specifics. 

> 	The driver is based on the HiDEOS support for the SCC2698 Octal UART which
