Data exchange between the driver and the PC is only initiated by the PC. All commands are sent in
plain text format. All commands are sent with prefix. Number of command follows the prefix without any
symbols. If there is the value after the command they separates with “space” symbol. The command ends
with “carriage return” symbol.
