Linux Minicom Serial Communication Program
Minicom is a freely available serial communication program that runs under LINUX™ and other UNIX™ operating system variants.linux distribution: ubuntu 10.04. Sudo apt-get install minicom. USB ttyUSB0 0.It was developed with the intent to provide a free, open source serial communications and modem control application for UNIX™-like computer systems. RUNSCRIPT(1) General Commands Manual RUNSCRIPT(1) NAME top runscript - script interpreter for minicom SYNOPSIS top runscript scriptname logfile homedir DESCRIPTION top runscript is a simple script interpreter that can be called from within the minicom communications program to automate tasks like logging in to a Unix system or your favorite BBS.Minicom is a freely available serial communication program that runs under LINUX™ and other UNIX™ operating system variants. It works by providing a terminal emulator for communicating with other devices via a computer's serial port. This can be a direct computer-to-computer communication or for controlling a modem connected to the serial port.
Linux Minicom Series Of Menu
2.1 Connect using a terminal emulator program 1 Configure console access on the target machine Minicom, however, is not a typical application with a graphical user interface (GUI). Instead, it runs via the command line and provides a text-based series of menu options for configuration. Once it is up and running, its operation is handled with keyboard commands and shortcut keys.
Linux Minicom Manual On Using
Edit refind.conf and uncomment textonly.To enable serial console in Syslinux, edit syslinux.cfg and add SERIAL as the first directive in the configuration file.For COM1 ( /dev/ttyS0) with baud rate of 115200 bit/s:The serial parameters are hardcoded to 8 bits, no parity and 1 stop bit. REFIndREFInd 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. For COM1 ( /dev/ttyS0) with baud rate of 115200 bit/s:GRUB_SERIAL_COMMAND="serial -unit=0 -speed=115200"Read GRUB's manual on Using GRUB via a serial line and the serial command for detailed explanation of the available options.Edit the GRUB Legacy configuration file /boot/grub/menu.lst and add these lines to the general area of the configuration:Note: When the terminal -timeout=5 serial console line is added to your menu.lst, your boot sequence will now show a series of Press any key to continue messages. 5.3 Missing ports on multi-port expansion cardsConfigure console access on the target machine Boot loader GRUBWhen using GRUB with a generated grub.cfg, edit /etc/default/grub and enable serial input and output support:Next add the GRUB_SERIAL_COMMAND variable and set the options for the serial connection. 4 Debugging an unresponsive machine using a serial console
The following example connect to /dev/ttyS0 at 115200 baud, with 8 data bits, no parity bit and 1 stop bit-times:Minicom can be obtained from the official repositories. If you invoke it without parameters, it will connect to /dev/ttyS0 at 9600 baud by default. Otherwise you will need root's permission to make a connection:See Users and groups#User groups for details.Perform these steps on the machine used to connect the remote console.Dterm AUR is a tiny serial communication program. For /dev/ttyS0 (COM1) that would be Enable the service to start it at boot.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.Making Connections Connect using a terminal emulator programNote: Before making a connection, it is recommended to add your user to the uucp group. The last specified console= will be set as /dev/console.At boot, systemd-getty-generator(8) will start a getty instance for each console specified in the kernel command line.If you have not configured console= in kernel command line start device.service.
It will connect at 9600 baud by default:A different baud rate (e.g. The following example connect to ttyS0 at 9600 bps:Note: if the backspace key will not work properly try out this option: '-omap delbs'GNU Screen is able to connect to a serial port. Optionally save the configuration by choosing save setup as dfl from the main menu.Restart minicom with the serial cable connected to the target machine.To end the session, press Ctrl+A followed by Ctrl+X.Picocom is a tiny dumb-terminal emulation program that is very like minicom, but instead of mini, it is pico. To do this, under the Modem and Dialing menu, delete the Init and Reset strings.
So it could be accessed normally before it needed debugging. And that it happened during normal operation. It is important to note that here, the machine under test got unresponsive in a reproducible manner. Cutecom AUR is another gui enabled serial monitor.Moserial is a gtk-based serial terminal, primarily intended for technical users and hardware hackers who need to communicate with embedded systems, test equipment, and serial consoles.Installing Arch Linux using the serial consoleNote: While a port speed of 9600 is used in most of the examples in this document, working with higher values is recommended (List of available speeds is displayed in Minicom by pressing 'Ctrl-A' and then 'P') Debugging an unresponsive machine using a serial consoleEven though has only raw and terse instructions, it presents the full scene. Install ruby package, then install it with the following:On Windows machines, connect to the serial port using programs like PuTTY or Terminalbpp. Alternatively, press Ctrl+a, type :quit and confirm it by pressing Enter.Serialclient is a CLI client for serial connection written in ruby.
This can cause weird problems with some full-screen programs (e.g. Also note the mentioned netconsole within the P.S paragraph of the external link from this section.If you are having trouble sending a Ctrl+c command through minicom you need to switch off hardware flow control in the device settings ( minicom -s), which then enables the break.Unlike ssh, serial connections do not have a mechanism to transfer something like SIGWINCH when a terminal is resized. Perhaps by configuring the boot loader by hand at machine startup time.
If you do not want to install xterm, it is possible to do the same work via a shell function. Invoke it without parameters after you resize the terminal emulator's window:2. There is a lesser-known utility called resize, shipped with xterm, that can solve this problem. The following methods should be simpler.1.
