QNX 6.3 instructions (specifically for Fastcom:422/4-PCI)

compile/copy the fcpci program to /sbin
copy/append the overrides file to /etc/system/enum


If you need a clock frequency different than the standdard (1843200) change 
the value of the set macro in the overrides file.
If you want the serial device to do the baud rate caluclations based on a nonstandard
rate, you must start the devc-ser8250 driver manually specifiying the clockrate with -c
(the 'fcpci -g' command leaves it at the default rates)
If you require other special features (of fcpci) add them to the overrides file
as start lines similar to the "start(/sbin/fcpci -d 0 0 1)" lines

note the fcpci code was hacked from the qnx 4.25 code,
and as a result it probably isn't the best way to accomplish this task
however it does appear to work on BigFan (P4) with a Fastcom:422/4-PCI card installed
using QNX 6.3 sp1.
