• If no response is detected the receiver retries sending start char three times (in total
four) before hanging up.
• If the receiver reads a message with checksum error it will reply with NAK (15h),
wait more than 500ms and then send a new start char (w).
• The receiver can optionally send a command back to the dialer after ACK.
The command may be one byte with any content except 'w' (77h), ACK (06h) or NAK
(15h)..
