messages to the machine:
-Information with the name of player 1
-Information with the name of player 2
-Synchronization of flashes
-Hour synchronization message
-Match assignment

an additional message confirming that it
has been received. The PC, in case this
confirmation is not received should be sent
the command again.
12.4- MESSAGE FORMAT
In general, the message format that the
PC sends to the Machines is:
DLE LEN IDMACH COMMAND+DATA CRC
-DLE: The byte of fixed heading
that always has the value 10H.
-LEN: The total length, including
DLE and CRC.
-CRC: The sum of all the bytes of
the message (Len-1), excluding CRC.
-ID: The Machine number. So that
the machine ‘listens’ to a message,
the number of the programmed machine

different commands that can be sent to
the machines.
