Определение протокола теперь примерно следующее:

COMMAND = METHOD [CONTENT]
METHOD = `SET` | `GET` | `ECHO` | BYTE
CONTENT = {
    METHOD=`SET`  => VARIABLE [DATA],
    METHOD=`GET`  => VARIABLE,
    METHOD=`ECHO` => BYTE,
    METHOD=BYTE   => any
}
VARIABLE = BYTE
DATA = any

BYTE = 1 any byte
any = any bytes

Метод SET используется для установки значения переменной VARIABLE в опциональное значение DATA. Метод GET -- для получения значения переменной VARIABLE или установки режима вывода. Метод ECHO -- для отправки принятых данных (байта) обратно (используется для проверки работоспособности USART).
