Configuration parameters starting with the “COMM_” prefix references the main serial port on the MTX-Terminal modem. Check the hardware manual of the MTX device to know which is the main serial port. This is the main port used to control and connect your device to and therefore needs to have same configuration, like baud rate.
Table of Contents
COMM_baudrate
Description: Serial COM1 port speed baud rate.
Possible values (bps):
- 460800, 230400, 115200, 57600, 38400, 19200, 9600, 4800, 2400, 1200, 600, 300
- Default value: 115200
Additional notes:
- You must use the same baud rate configuration with your device and MTX-Tunnel
COMM_autorts
Description: This parameter configures the COM1 serial port to have hardware flow control (RTS line). If enabled (value=”on”) then hardware flow control will be used, otherwise (value=”off”) means no hardware flow control will be used.
Possible values:
- on, off
- Default value: on
Additional notes:
- Configuration of the device connected to the modem and MTX-Tunnel must be the same
- Use the same value in COMM_autocts parameter
COMM_autocts
Description: This parameter configures the COM1 serial port to have hardware flow control (CTS line). If enabled (value=”on”) then, hardware flow control will be used, otherwise (value=”off”), no hardware flow control will be used.
Possible values:
- on, off
- Default value: on
Additional notes:
- Configuration of the device connected to the modem and MTX-Tunnel must be the same
- Use the same value in COMM_autorts parameter
COMM_bitsperchar
Description: COM1 serial port number of bits per character.
Possible values:
- 7, 8
- Default value: 8
Additional notes:
- Configuration of the device connected to the modem and MTX-Tunnel must be the same.
COMM_stopbits
Description: Number of stop bits per character in COM1 serial port.
Possible values:
- 1
- Default value: 1
Additional notes:
- Configuration of the device connected to the modem and MTX-Tunnel must be the same
- From version 7.27, 2 bits of data can be specified. 2 bit data communications can be slower than those of 1 stop bit, especially with large volume data communications. 1 stop bit is recommended when possible.
COMM_parity
Description: Parity used in COM1 serial port communication.
Possible values:
- none, odd, even
- Default value: none
Additional notes:
- Configuration of the device connected to the modem and MTX-Tunnel must be the same
