mfterm

mfterm [options] [device]

-b
    Sets the baud rate for the serial port.

-d
    Sets the number of data bits (e.g., 7 or 8).

-p
    Sets the parity (e.g., none, even, odd).

-s
    Sets the number of stop bits (e.g., 1 or 2).


    Specifies the serial device to use (e.g., /dev/ttyS0 or /dev/ttyUSB0).

mfterm is a simple, terminal-based serial communication program designed for Linux. It provides a basic interface for interacting with devices connected via serial ports, such as microcontrollers, modems, and other embedded systems. mfterm typically offers functionalities like setting the baud rate, data bits, parity, and stop bits, as well as sending and receiving data. While it may lack the advanced features of more sophisticated terminal emulators, its simplicity makes it useful for basic serial communication tasks and debugging. It's particularly useful in situations where a lightweight and direct approach to serial port interaction is needed. Its configuration is handled primarily through command-line options, allowing quick setup and operation.
It's often favored for its small footprint and ease of use in embedded development and system administration scenarios where direct serial communication is essential.

The specific options and features may vary depending on the version of mfterm installed. It is a relatively basic terminal emulator and lacks some features found in more advanced programs.

mfterm needs permissions to access the serial device. Users may need to be added to a group (e.g., dialout) to have the necessary permissions, or the device permissions may need to be adjusted.
