Features:

• Command mode. Press CTRL-B (default key mapping) to enter. Example send raw hex and toggle DTR. This is also "scriptable" from command line options which allow for sending a string after serial port is opened.

• Canonical or raw mode.

• handle frequent disconnect and reconnect of serial device. never miss boot log message and no need to reconnect after power cycle.

• sticky/async prompt. Handle async output to stdout without interrupting user input.

• Cross platform. Built upon sigroks/libserialport and libuv - both supported on GNU/Linux, MacOS, BSD, Android and more (currently windows need some extra workarounds).

• Sanitization of data before printed to stdout (does not mess up terminal settings).

• autocomplete on serial devices and common baudrates

• list serial devices. try spcom -lvv for more verbose output.

On Debian/Ubuntu, install these packages:

apt install libserialport-dev libuv1-dev libreadline-dev
`sudo apt install build-essential`

cd spcom mkdir build cd build cmake .. make

clean:

cmake [--build ] --target clean

with clang:

cmake --build build --target clean cd build/

cmake -D CMAKE_C_COMPILER=/usr/bin/clang-7 .. make

Alternatives
============

- [picocom](https://github.com/npat-efault/picocom) most notable mention. Currently missing support for canonical input.
- [screen](https://linux.die.net/man/1/screen) - do not handle high baudrate 
- [minicom](https://linux.die.net/man/1/minicom) - menu driven.
- [putty](https://www.putty.org/) windows and unix support.
- [gtkterm](https://github.com/Jeija/gtkterm)
- [cu](https://linux.die.net/man/1/cu)
- [conman](https://github.com/dun/conman) similar to picocom
- [necon](https://github.com/aitjcize/neocon) have "watch functionality"
- [pyserial/tools/miniterm](https://github.com/pyserial/pyserial)
- something similar might be achivable with a combination of `stty`, `socat` and `inotify`. 
- [grabserial](https://github.com/tbird20d/grabserial) python
