ASYHDLC(7)                                                ASYHDLC(7)


       NAME
             ASYHDLC - ASYnchronous HDLC protocol device

       SYNOPSIS
             asyhdlc

       DESCRIPTION
             The ASYHDLC device is attached to an asynchronous serial line
             so that PPP may use that line to transmit and receive IP
             datagrams.

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

                   generates and validates the CRC checksum

                   encodes and decodes packet data to achieve data
                   transparency - character stuffing

                   generates and strips framing patterns delimiting packet
                   start and end

             See PPP(7) for additional information about the PPP
             implementation.
