The following example connect to ttyS0 at 9600 bps: Picocom is a tiny dumb-terminal emulation program that is very like minicom, but instead of mini, it is pico. To end the session, press Ctrl+A followed by Ctrl+X. Restart minicom with the serial cable connected to the target machine. Optionally save the configuration by choosing save setup as dfl from the main menu. To do this, under the Modem and Dialing menu, delete the Init and Reset strings.

Remove the modem Init and Reset strings, as we are not connecting to a modem. Press Enter to exit the menus (pressing Esc will not save changes). Using the textual navigation menu, change the serial port settings to the following: Minicom can be obtained from the official repositories. The following example connect to /dev/ttyS0 at 115200 baud, with 8 data bits, no parity bit and 1 stop bit-times: If you invoke it without parameters, it will connect to /dev/ttyS0 at 9600 baud by default. Perform these steps on the machine used to connect the remote console.Дterm AUR is a tiny serial communication program. See Users and groups#User groups for details. Otherwise you will need root's permission to make a connection: Note: Before making a connection, it is recommended to add your user to the uucp group. Making Connections Connect using a terminal emulator program Unless specified otherwise in the kernel command line, getty will be expecting 38400 bit/s baud rate, 8 data bits, no parity and one stop bit-times. For /dev/ttyS0 (COM1) that would be Enable the service to start it at boot. If you have not configured console= in kernel command line start rvice.

The last specified console= will be set as /dev/console.ДЄt boot, systemd-getty-generator(8) will start a getty instance for each console specified in the kernel command line. Kernel's output can be sent to serial console by setting the console= kernel parameter. Read Syslinux Wiki:Config#SERIAL for the directive's options. The serial parameters are hardcoded to 8 bits, no parity and 1 stop bit.

To enable serial console in Syslinux, edit syslinux.cfg and add SERIAL as the first directive in the configuration file.ДЇor COM1 ( /dev/ttyS0) with baud rate of 115200 bit/s: REFInd supports serial console only in text mode. If no key is pressed, the boot menu will appear on whichever (serial or console) appears first in the terminal configuration line.
