Data exchange between the driver and the PC is only initiated by the PC. All commands are
sent in plain text format. All commands in text-plain mode should be in ASCII. 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.
The format of the command to set the value (P-type):
