asyhdlc(ADMP)


asyhdlc -- asynchronous High-level Data Link Control (HDLC) protocol module

Description

The asyhdlc module is part of the STREAMS protocol stack used for PPP connections. pppd(ADMN) pushes asyhdlc onto the mbcl(ADMP) driver. mbcl links the PPP driver with tty lines. asyhdlc implements part of RFC 1548, one of the PPP protocol standards.

A PPP HDLC packet lacks a CRC checksum and uses a ``transparent code'' for data transmission. asyhdlc performs the following functions on PPP datagrams:

See ppp(ADMP) for additional information about the PPP implementation.
