/**

|
* Driver for the RS-232 serial port on the RoboRIO.
|
|
*
|
|
* The current implementation uses the VISA formatted I/O mode. This means that
|
|
* all traffic goes through the fomatted buffers. This allows the intermingled
|
|
* use of Printf(), Scanf(), and the raw buffer accessors Read() and Write().
|
|
