microcom

minimalistic terminal program for accessing remote devices via serial

TLDR

Open a serial port using the specified baud rate
$ microcom -p [/dev/ttyXYZ] -s [baud_rate]
Establish a telnet connection to the specified host
$ microcom -t [hostname]:[port]

SYNOPSIS

microcom [options]

DESCRIPTION

microcom is a minimalistic terminal program for accessing remote devices via serial ports, CAN bus, or telnet connections from the console. It provides a simple, lightweight alternative to programs like minicom for basic serial communication needs.The program passes data between the terminal and the remote device, useful for accessing embedded systems, routers, network equipment, and other devices with serial console interfaces.Exit microcom by pressing Ctrl+\\ followed by q (or the configured escape sequence).

PARAMETERS

-p, --port _device_

Serial port device to connect to (e.g., /dev/ttyUSB0)
-s, --speed _baud_
Baud rate for serial communication (e.g., 9600, 115200)
-t, --telnet _host:port_
Connect via telnet to the specified host and port
-c, --can _interface_
Connect to a CAN bus interface
-l, --logfile _file_
Log session to a file

INSTALL

sudo apt install microcom
sudo zypper install microcom
nix profile install nixpkgs#microcom

CAVEATS

Serial port access typically requires appropriate permissions (membership in the dialout group on most Linux systems). The device must be configured for the correct baud rate, parity, and stop bits to match the remote device. No built-in file transfer protocols like XMODEM or ZMODEM.
