-# This is a minimal example configuration file for ser2net. For a version with
-# detailed comments and all possible configuration directives, please visit:
-# https://github.com/cminyard/ser2net/blob/master/ser2net.conf
-#
-# On OpenWrt/LEDE systems, this configuration serves as a base configuration.
-# During boot of the system, the UCI configuration file /etc/config/ser2net is
-# parsed and converted to additional configuration lines which are _appended_
-# to this file. The ser2net daemon is then started with the combined
-# configuration file /tmp/ser2net.conf.
-#
-# A basic service configuration line has the following format:
-# <network port>:<state>:<timeout>:<device>:<options>
-# network port
-# Name or number of the port to accept connections
-# from for this device. A port number may be of the form
-# [ipv4,|ipv6,][tcp,|udp,][host,]port, such as
-# 127.0.0.1,2000 or ipv4,tcp,localhost,2000. If the host is
-# specified, it will only bind to the IP address
-# specified. Otherwise it will bind to all the ports on the
-# machine. If ipv4 or ipv6 is specified, it will only bind
-# to that network type.
-#
-# state
-# Either raw or rawlp or telnet or off. off disables
-# the port from accepting connections. It can be
-# turned on later from the control port. raw enables
-# the port and transfers all data as-is between the
-# port and the long. rawlp enables the port and
-# transfers all input data to device, device is open
-# without any termios setting. It allow to use
-# /dev/lpX devices and printers connected to them.
-# telnet enables the port and runs the telnet proto-
-# col on the port to set up telnet parameters. This
-# is most useful for using telnet.
-#
-# timeout
-# The time (in seconds) before the port will be dis-
-# connected if there is no activity on it. A zero
-# value disables this function.
-#
-# device
-# The name of the device to connect to. This
-# must be in the form of /dev/<device>.
-#
-# options
-# Sets operational parameters for the serial port.
-# For a serial device (not IPMI SOL):
-# Options 300, 1200, 2400, 4800, 9600, 19200, 38400,
-# 57600, 115200 set the various baud rates. EVEN,
-# ODD, NONE (MARK and SPACE if supported) set the parity.
-# Note that MARK and SPACE are not available on all systems
-# or hardware, if it is not supported then it will be
-# silently set to ODD or EVEN parity.
-# 1STOPBIT, 2STOPBITS set
-# the number of stop bits. 5DATABITS, 6DATABITS,
-# 7DATABITS, 8DATABITS set the number of data bits.
-# [-]XONXOFF turns on (- off) XON/XOFF support.
-# [-]RTSCTS turns on (- off) hardware flow control,
-# [-]LOCAL turns off (- on) monitoring of the modem lines,
-# and [-]HANGUP_WHEN_DONE turns on (- off) lowering the
-# modem control lines when the connection is done.
-# [-]NOBREAK disables automatic setting of the break
-# setting of the serial port.
-#
-# The "[-]remctl" option allow remote control (ala RFC
-# 2217) of serial-port configuration.
-#
-# Example:
-# 5000:telnet:0:/dev/ttyAPP0:115200 8DATABITS NONE 1STOPBIT -XONXOFF -LOCAL -RTSCTS remctl
