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