Serial port over TCP/UDP settings
The GWR-I Router provides a way for a user to connect from a network connection to a serial port.
It provides all the serial port setup, a configuration file to configure the ports, a control login for modifying
port parameters, monitoring ports, and controlling ports. The GWR-I Router supports RFC 2217 (remote
control of serial port parameters).
Serial Port over TCP/UDP Settings
Label Description
Standard Indicates the standard for serial connection (RS232, RS485 2W, RS485 4W).
Bits per second
The unit and attached serial device, such as a modem, must agree on a speed or
baud rate to use for the serial connection. Valid baud rates are 300, 1200, 2400,
4800, 9600, 19200, 38400, 57600 or 115200.
Data bits Indicates the number of bits in a transmitted data package.
Parity Checks for the parity bit. None is the default.
Stop bits
The stop bit follows the data and parity bits in serial communication. It
indicates the end of transmission. The default is 1.
Flow control
Flow control manages data flow between devices in a network to ensure it is
processed efficiently. Too much data arriving before a device is prepared to
manage it causes lost or retransmitted data. None is the default.
Protocol Choose which protocol to use [TCP/UDP].
Mode
Select server mode in order to listen for incoming connection, or client mode to
establish one.
Bind to TCP/UDP port
Number of the TCP/UDP port to accept connections for this device. (Only on
server side)
Server IP address Specify server IP address. (Only on client side)
Connect to TCP/UDP
port Number of the TCP/UDP port to accept connections from this device. (Only on
client side)
Type of socket
Either raw or telnet . Raw enables the port and transfers all data like between the
port and the log. Telnet enables the port and runs the telnet protocol on the
port to set up telnet parameters.
Enable local echo Enable the local echo feature.
Check TCP connection Enable connection checking.
Kepalive idle time Set keepalive idle time in seconds.
Kepalive interval Set time period between checking.
Log level Set importance level of log messages.
