Linux Serial Terminal Program
Serial Terminal Basics. Similar to Windows, Mac OS and Linux assign a specific port to every device attached to the computer. However, unlike Windows, there is no specific program you can open up to view all the devices currently attached. They decided to included a serial terminal with the software. Within the Arduino environment, this. And you'll need to port-forward your router for that port, to the PC on which serproxy runs (that PC should use a static IP in your NATed LAN). It's very easy to download, setup and run. Your friend would just use his Linux shell window and issue a telnet to the IP and port #. And on his end, run whatever he wishes in terms of terminal program. Serial Connection Emulator v.1.0.1 ttypatch is a Linux application that permits two or more 'serial port user programs' to reliably connect to each other without the use of actual serial ports. Also acts as a virtual patch panel among any number of real and virtual serial. The terminal is the beating heart of Linux, no matter how hard today’s user-friendly graphical distros might try to push it into the background. If you need something done quickly. This is a list of notable terminal emulators.Most used terminal emulators on Linux and Unix-like systems are GNOME Terminal on GNOME and GTK-based environments, Konsole on KDE, and xfce4-terminal on Xfce as well as xterm.
On Linux, I want to send a command string (i.e. some data) to a serial port (containing control characters), and listen to the response (which also usually might contain control characters).
How can I do this as simplest as possible on Linux? An example is appreciated!

All devices on Unix are mapped to a device file, the serial ports would be /dev/ttyS0
/dev/ttyS1
.. .
First have a look at the permissions on that file, lets assume you are using /dev/ttyS1
.
ls -l /dev/ttyS1
You will want read.write access, if this is a shared system then you should consider the security consequences of opening it up for everyone.
A very simple crude method to write to the file, would use the simple echo
command.
and to read
You can have cat running in one terminal, and echo in a 2nd.
If everything is gibberish, then baud rate, bit settings might need setting before you start sending. stty
will do that. !! NOTE stty will use stdin as default file descriptor to affect.
Equivalent commands.
This might be enough for you to script something and log ? Not sure what you are trying to achieve.
For a more interactive, remembers your default settings approach would be to useminicom
it is just a program which does everything I've mentioned so far. (similar to hyperterminal in Windows, you might be familiar).
An intermediate solution, would use a terminal program like screen
which will work on a serial device.
man screen
man minicom
man stty
for more information
All you have to do is open two terminals. In the first terminal you cat
everything from the device, e.g.
in the other terminal, you can send arbitrary hex characters and text to the terminal e.g. as follows:
The echo -e
command enables the interpretation of backslash escapes.
One has to make sure of course that (i) the serial settings (speed, word length, flow ctrl, etc) are correct and (ii) the serial device (on the other end) is not blocking.

or from shell you can do:
You can read and write to a device simulataneously like so:
Your message is sent to the second cat
from stdin
, and the first cat
relays the response to stdout
, turning your terminal into a chatroom.
To finish up, ctrl-c
, then run fg
then ctrl-c
again.

An Arch Linux machine can be configured for connections via the serial console port, which enables administration of a machine even if it has no keyboard, mouse, monitor, or network attached to it.
Installation of Arch Linux is possible via the serial console as well.
A basic environment for this scenario is two machines connected using a serial cable (9-pin connector cable).The administering machine can be any Unix/Linux or Windows machine with a terminal emulator program (PuTTY or Minicom, for example).
The configuration instructions below will enable boot loader menu selection, boot messages, and terminal forwarding to the serial console.
- 1Configure console access on the target machine
- 1.1Boot loader
- 2Making Connections
- 2.1Connect using a terminal emulator program
- 2.1.1Command line
- 2.1Connect using a terminal emulator program
- 4Troubleshooting
Configure console access on the target machine
Boot loader
GRUB
When using GRUB with a generated grub.cfg
, edit /etc/defaults/grub
and enable serial input and output support:
Next add the GRUB_SERIAL_COMMAND
variable and set the options for the serial connection. For COM1 (/dev/ttyS0
) with baud rate of 115200 bit/s:
Read GRUB's manual on Using GRUB via a serial line and the serial command for detailed explanation of the available options.
GRUB Legacy
Edit the GRUB Legacy configuration file /boot/grub/menu.lst
and add these lines to the general area of the configuration:
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. If no key is pressed, the boot menu will appear on whichever (serial or console) appears first in the terminal
configuration line.rEFInd
rEFInd supports serial console only in text mode. Edit refind.conf
and uncomment textonly
.
Syslinux
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.[1]. Read Syslinux Wiki:Config#SERIAL for the directive's options.
Kernel
Kernel's output can be sent to serial console by setting the console=
kernel parameter. The last specified console=
will be set as /dev/console
.
See https://www.kernel.org/doc/Documentation/admin-guide/serial-console.rst.
getty
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 startserial-getty@device.service
. For /dev/ttyS0
(COM1) that would be serial-getty@ttyS0.service
. 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
Linux Serial Terminal Program Windows 7
Connect using a terminal emulator program
uucp
group. 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.
Command line
dterm
dtermAUR is a tiny serial communication program. If you invoke it without parameters, it will connect to /dev/ttyS0
at 9600 baud by default. The following example connect to /dev/ttyS0
at 115200 baud, with 8 data bits, no parity bit and 1 stop bit-times:
See its homepage[2] for more examples.
Minicom
minicom can be obtained from the official repositories. Start Minicom in setup mode:
Using the textual navigation menu, change the serial port settings to the following:
Press Enter to exit the menus (pressing Esc will not save changes).Remove the modem Init and Reset strings, as we are not connecting to a modem. To do this, under the Modem and Dialing
menu, delete the Init and Reset strings. 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
picocom is a tiny dumb-terminal emulation program that is very like minicom, but instead of mini, it is pico. The following example connect to ttyS0
at 9600 bps:
See its manual for detailed usage.
Screen
GNU Screen is able to connect to a serial port. It will connect at 9600 baud by default:
A different baud rate (e.g. 115200) may be specified on the command line.
To end the session, press Ctrl+a
followed by K
. Alternatively, press Ctrl+a
, type :quit
and confirm it by pressing Enter
.
Serialclient
Serialclient[3] is a CLI client for serial connection written in ruby. Install it with the following:

Installing Arch Linux using the serial console
ttyS0
/COM1) at 38400 bps, with 8 data bits, no parity bit and 1 stop bit-times.- Connect to the target machine using the method described above.
- Boot the target machine using the Arch Linux installation CD.
- When the bootloader appears, select Boot Arch Linux (<arch>) and press
Tab
to edit - Append
console=ttyS0,38400
and pressEnter
. - Now systemd should detect ttyS0 and spawn a serial getty on it. Login as
root
and start the installation as usual.
Troubleshooting
Ctrl-C and Minicom
If you are having trouble sending a Control-C command through minicom you need to switch off hardware flow control in the device settings (minicom -s), which then enables the break.

Resizing a terminal
Unlike ssh, serial connections do not have a mechanism to transfer something like SIGWINCH
when a terminal is resized. This can cause weird problems with some full-screen programs (e.g. less
) when you resize your terminal emulator's window.
Sony ericsson cell phones. Resizing the terminal via stty
is a workaround:
However, this requires you to manually input the proper geometry. The following methods should be simpler.
1. There is a lesser-known utility called resize
, shipped with xterm, that can solve this problem. Invoke it without parameters after you resize the terminal emulator's window:
2. If you don't want to install xterm, it is possible to do the same work via a shell function. Put the following function into your zshrc and invoke it without parameters after resizing the terminal emulator's window:
