Should I be using 
ecos\packages\devs\serial\arm\at91\current\src\at91_serial.c or 
something else, such as

I'd just like the security of some macros intended to mean "ecos will 
definitely not be doing anything with this serial port".  For instance, 
I've disabled CYGPKG_IO_SERIAL_ARM_AT91_SERIAL0 and it doesn't seem to 
have made any difference.
