AT-S can receive the various parameters using System Exclusive messages.
F7H
The exclusive message of GS format data has a model ID of 42H and a device ID of 10H (17),
and it is common to all the GS devices.
This is the message that actually performs data transmission, and is used when you wish to
transmit the data.
