IOPORTSetPort.c
PROJECTS:
IOPort only.
AUTHORS:
Allen.Ingling@nyu.edu awi
mario.kleiner at tuebingen.mpg.de mk
PLATFORMS:
All.
HISTORY:
12/20/2004 awi Wrote it.
04/10/2008 mk Started to extend/rewrite it to become a full-fledged generic I/O driver (serial port, parallel port, etc...).
DESCRIPTION:
Originally controlled the Code Mercenaries IO Warrior 40 device.
It will hopefully become a generic I/O driver...
