NAME

sercd - RFC 2217 Serial Communications Daemon

SYNOPSIS

sercd [-ie] [-p port] [-l addr] <loglevel> <device> <lockfile> [pollingterval]

DESCRIPTION

This manual page documents briefly the sercd, 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

-i

Enable compatability with Cisco IOS.

-e

Send output to standard error instead of syslog.

-p port

Listen on specified port, instead of port 7000.

-l addr

Standalone mode, bind to specified adress, empty string for all.

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 sercd from talking to the serial port at the same time, or to allow sharing a port between modem and sercd.

EXAMPLE

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