FILTER-SLIP(2)FILTER-SLIP(2)NAME
slip - SLIP data framing protocol
SYNOPSIS
include "filter.m";
slip := load Filter Filter->SLIPPATH;
init: fn();
start: fn(param: string): chan of ref Rq;
DESCRIPTION
Slip provides the SLIP data framing protocol described by RFC1055. The
module is an implementation of the general data-processing module type
Filter; see filter(2) for details of that general interface.
Init must be called before any other operation of the module.
Start begins SLIP line encoding or decoding via the channel it returns,
following the protocol of filter(2). Param is one of the two following
strings:
encode The filter takes the block of data obtained by each Rq.Fill mes‐
sage, adds framing and escape characters as required, and
returns the resulting data block in an Rq.Result message.
decode The filter operates on the data in Rq.Fill messages as a single
stream of bytes, providing an Rq.Result message for each framed
message found in the stream, with escape characters processed to
retrieve the original data.
