sredird(8)							      sredird								sredird(8)

NAME

       sredird - RFC 2217 serial port server

SYNOPSIS

       sredird [-i] log-level serial-device lock-file [poll-interval]

DESCRIPTION

       This manual page documents briefly the sredird, program.

       This  program  when  run  through inetd will use the RFC 2217 extensions to TELNET to implement serial commands over the TCP connection and
       interface to a specified serial port.

OPTIONS

       An optional first parameter is '-i' to enable compatability with Cisco IOS.

       The first mandatory parameter is the log level for use in syslog.  The next mandatory parameter is the device node for the  serial  device,
       it  must  be  a	fully  qualified  path.   The  final mandatory parameter is the file name for the lock file to be used to prevent multiple
       instances of sredird from talking to the serial port at the same time, or to allow sharing a port between modem and sredird.

EXAMPLE

       Here is a configuration line for running it from inetd: sredir	       stream  tcp     nowait  root    /usr/sbin/tcpd /usr/sbin/sredird  5
       /dev/modem /var/lock/LCK..modem
