# SLIP.CFG
#
# SLIP Configuration File
# ..................................................
#
# Copyright (c) 1993

#
# This file controls the interfaces that the SLIP driver creates and manages.
# It is used to set up interface values (such as MTU, RTT estimates, and
# device information), as well as specifying other per-interface data, such
# as what scripts should be run to make a SLIP attachment over an interface.
#
# The general format of the file is a series of interface "clauses", of the
# form:
#
# interface ??? { # Comments
# parameter = value [,] [ parameter = value [,] ... ]
# }
#
# Spaces, commas and newlines are ignored (except within quoted strings).
# In general, the layout of the file is free-form, within the general bounds
# of the interface blocks.
#
# Comments may begin at any point on the line, and are signified by a hash
# (#) character - everything past the comment character is ignored.
#
# Parameter names and values are delimited by whitespace. Special characters
# (whitespace, ',', '{', '}', '#', '=') may be included in a value by
# surrounding that value in double quotes ("), or by prefixing the special
# character with a backslash (\). Use \\ to get a backslash itself, and use
# \" within a quoted string to get a double quote within the value.
#
# In the above, ??? specifies an interface to be defined. Currently only
# two values are allowed:
#
# default Default settings. Specifies parameters that will
# be assumed for any interfaces later in the file
# where their interface clauses do not contain new
# values for the parameters.
# sl0 Serial Interface 0.
#
# The "interface default" clause may be specified multiple times, and is
# additive. Where a parameter appears in more than one such clause, its
# most recent value will be used for any later interface clauses.
#
# The following parameters and values are allowed for each interface:
#
# Basic Parameters
# device Interface serial device (ie: "com1")
# mtu Maximum transmission unit (bytes)
# compression Adjusts VJ compression. Can be "ON" (always compress),
# "OFF" (never), or "AUTO" (accept compression and
# start compressing if compressed packets are received)
# attachcmd Name of rexx command script to run to attach interface
# attachparms Parameters to pass to command script
#
# Queuing Parameters
# fastqueue Enables priority queueing for interactive traffic.
# nofastqueue Disables priority queueing
# queuesize Normal and priority queue sizes (IP kernel<->SLIP) in
# fastqueuesize packets. These should be multiples of 4.
#
# Protocol Parameters
# rtt Initial TCP RTT estimates. Like BSD-Reno's per-route
# rttvar defaults, but per-interface. The values assigned
# rttmin to these parameters are in milliseconds
# sendpipe Size of TCP send and receive windows (bytes)
# recvpipe
# ssthresh "Slow start" congestion window threshold (bytes)
#
# When this file is initially processed, the system default interface clause
# is as follows:
#
# interface default {
# mtu=296, compression=on,
# fastqueue, queuesize=12, fastqueuesize=24,
# recvpipe=4096
# }
#
# And the default device for the "sl0" interface is "com1"
#
# It is not recommended that anything other than "Basic Parameter" values
# be adjusted unless truly necessary. In particular, adjusting queue sizes
# and rtt* values without a complete understanding of the effect such
# adjustments will have on protocol (such as TCP) behavior can seriously
# affect both interactive response and throughput.
#
# The "attachparms" must contain in this order: the userid, the password,
# and the dial command(s). If any of these is specified as an asterisk (*),
# the script will prompt you for that value. You can specify several dial
# commands, each will be tried in turn until a connection is established.
#
#------------------------------------------------------------------------------
# Set up a simple default sl0 (default parameter values commented above)
#
interface sl0 {
device=COM1,
mtu=1006,
compression=on,
attachcmd=xs4all,
attachparms="userid password atdt020-6222175 atdt020-6265060"
}
