Is this a hard-coded value in the driver station?
This was a mechanism that allowed the field to ask the robot if its version matched the one sent. The value is simply relayed by the DS. It is not necessary for a DS implementation.

Keep in mind that the protocol is changing significantly for the roboRIO.
