Here is a paraphrase of the Google AI response to "Linux Serial app"
In recent years when Chromebooks and Chromeboxes had their own app store
there were many apps for serial file transfer. In the Chrome OS world of
today one would activate the Linux Development Environment. From there the
below options should be available to use: I like the option of "piping" the
content to transfer directly from the Linux terminal (see command line
tools) I'll have to try that, though I don't use Chrome OS myself.
AI Overview
Several applications facilitate serial communication on Linux, catering to
various needs from basic terminal interaction to advanced data handling.
Command-line Tools:
- *screen:* A full-screen window manager that can connect to serial
devices. It is useful for basic interaction and monitoring.
Code
screen /dev/ttyUSB0 9600
(This connects to /dev/ttyUSB0 at 9600 baud.)
- *minicom:* A console-based serial communication program offering a
menu-driven interface for configuration and interaction. It provides more
features than screen for managing serial sessions.
Code
minicom -b 9600 -D /dev/ttyUSB0
- *tio:*
A straightforward command-line tool designed for easy connection and
interaction with serial TTY devices. It supports configuration files for
persistent settings.
- *stty and echo:*
For basic sending and receiving, you can configure the serial port with
stty and then redirect echo output to the device or read from it
directly.
Code
stty -F /dev/ttyUSB0 speed 9600
echo "helloworld" >/dev/ttyUSB0
Graphical Applications:
- *CuteCom:*
A graphical serial terminal application built with the Qt library. It
offers a line-oriented interface, xmodem/ymodem/zmodem support, and
hexadecimal input/output, making it suitable for hardware developers.
- *Moserial:*
A graphical serial terminal program for Linux, often compared to
RealTerm on Windows, providing a user-friendly interface.
- *Putty:*
While primarily known as an SSH client, Putty also supports serial
connections and is available on Linux.

A C++ object-oriented library for interacting with RS-232-like devices
on Linux, Mac OS X, and Windows. It provides a robust interface for
developers needing fine-grained control over serial communication.

A GitHub project offering a test application for Linux serial ports,
useful for verifying functionality and debugging.
Permissions:
- To access serial ports, ensure your user account is part of the
dialout group
or the group that owns the serial port device. You can add your user to the
dialout group using:
Code
sudo usermod -a -G dialout $USER
(You may need to log out and back in for changes to take effect.)
