The receiving program first sends the negotiation character to negotiate the check mode.
After the negotiation is successful, the sending program begins to send packets.
When the receiving program receives a complete packet, it checks the packet in the
negotiated mode.
If the check is successful, the receiving program sends the acknowledgement character and
then the sending program sends the next packet.
If the check fails, the receiving program sends the denial character and the sending program
retransmits the packet.
