Message waiting time (CMDR)
This is the delay time of the reply message, required by some computers to switch over
between the state of transmission and the state of reception.
The awaiting time determines the minimum delay before the Replay sends data in reply to
the message received from the Master. Set this time at a value different from 0 only if the
specifications of the Master demand it, since the delay determines an extension of the time
needed to complete the command.
