Serial programming on FreeBSD 6.0 RELEASE

[Derek Ragona]

Let me try this again.  Programing the uart directly means directly 
manipulating the serial port chip.  Programing in c or c++ does not usually 
do this, as you normally would open the device/file and simply read or 
write to it.  In opening the device you need to set it to unbuffered in the 
flags when you do the open call.
