* PURPOSE: This function sends the PCCC Write Bytes Physical command to
* the PLC–5/40V.
*
* INPUT: ULONG vmeCmdBlkAddr contains the VME address where the
* command block will be copied to so the PLC–5/40V can
* access its information.
*
* UWORD baseAddress contains the base address of the
* PLC–5/40V.
