This command will cause the gateway to do a complete cold start.  The gateway will ignore the next message.

Time Stamp  
This command controls whether a 16 bit time stamp is appended to the end of the bus message reports.

This command controls whether transmitted messages are echoed back to the host when they are sent.  Echoed 
back messages will have their transmit bit set.
  Currently the transmit echo is disabled.

Software Version Request 
This command requests the gateway software version (ASCII).

This command will cause the gateway to toggle the trigger LED upon receiving the specified byte pattern.  Up to 
12 data bytes may be used.  This feature is helpful for triggering an oscilloscope. (Not available with IDB firmware)
