Detailed Protocol Description
HDLC frame, the unexpected characters are discarded before forwarded to the receive
CRC checking unit.
7D
(control-escape) and 7E
(flag) octets in the data stream are mapped in general.
H
H
The sequence of mapping control logic is:
1. 7D
and 7E
octets,
H
H
2. ACCM0..3,
3. UDAC0..3.
This mechanism is applied to asynchronous HDLC PPP mode as well as to octet
synchronous HDLC PPP mode.
