Template:Networking rutos manual serial utilities rut2 rut9
The information in this page is updated in accordance with firmware version .
Summary
The Serial Utilities page is used to make serial communication configurations of different types. To make a new serial configuration instance select a serial type from the left-hand navigation menu. In the next page enter a custom name for the new config, select a serial device and click the Add button.
Example from the Modem Configuration page:

Then, click the Edit button next to the instance:

This manual page provides an overview of the Serial Utilities page in {{{name}}} devices.
Modem Control
The Modem serial type is used to manage modem functionality which could be accessed using shell interface. For this purpose you may want use CR/LF (Carriage Return, Line Feed) capable applications like PuTTY on Windows and microcom, minicom, cutecom or similar applications on Linux.

| Field | Value | Description |
|---|---|---|
| Enable | off | on; default: off | Turns the instance on or off. |
| Name | string; default: none | Instance name, generated by the user when first creating the configuration. |
| Device | ; default: | Specifies which serial port will be used for serial communication. |
| Baud rate | integer [300..3000000]; default: 9600 | Data rate for serial data transmission (in bits per second (bps)). |
| Data bits | 8; default: 8 | Number of data bits for each character. |
| Stop bits | 1 | 2; default: 1 | Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to resynchronise with the character stream. Electronic devices usually use one stop bit. Two stop bits are required if slow electromechanical devices are used. |
| Parity | None | Odd | Even | Mark | Space; default: None | In serial transmission, parity is a method of detecting errors. An extra data bit is sent with each data character, arranged so that the number of 1 bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then it must have been corrupted. However, an even number of errors can pass the parity check.
|
| Flow control | None; default: None | In many circumstances a transmitter might be able to send data faster than the receiver is able to process it. To cope with this, serial lines often incorporate a "handshaking" method, usually distinguished between hardware and software handshaking. |
| Mode | Partial control | Full control; default: Partial control | Specifies modem control mode.
|
| Start up message | string; default: none | Message to print to serial device when modem control is ready. |
Console
Console mode requires no further configuration than the settings above and is used as a direct-access method to the device's shell interface. For this purpose you may want use such applications as PuTTY on Windows and microcom, minicom, picocom or similar applications on Linux.

Over IP
The Over IP serial type is used to manage serial connections over a TCP/IP network.
Serial Device Configuration
Configure serial port communication parameters in the Serial Device Configuration section.
