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).
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. Traditionally in Linux, the first serial port (COM1) is assigned a name /dev/ttyS0, the second serial port (COM2) assigned /dev/ttyS1, etc. If you specify a serial port name as the first argument of the screen command, the current terminal window where you run screen will be directly connected to the serial port.
How can I do this as simplest as possible on Linux? An example is appreciated!
Serial terminal program for engineering. Ideal for development, reverse engineering, debugging, datalogging and capture, and automatic test. The website is a comprehensive manual for Realterm. It has an comprehensive ActiveX/COM automation support so it can be used a serial component by other programs. A Terminal emulator is a computer program that reproduces a video terminal within some other display structure. In other words the Terminal emulator has an ability to make a dumb machine appear like a client computer networked to the server. The terminal emulator allows an end user to access console. How to write characters to serial port. Ask Question Asked 5 years, 7 months ago. Active 4 years ago. Viewed 26k times 2. I have an ancient serial spectrometer which only runs on win9x. I want to convert to a Linux system, but the existing software is proprietary and wont work. I was able to access a console internally on the spectrometer.

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 use
minicom
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

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.

Programs that talk to serial devices:
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.diachedelicdiachedelic
