Normal Use

minicom -b 115200 -o -D /dev/ttyACM0

To quit: [C]-a then z then q then Enter


To run Minicom on a remote system, telnet into that system and use

minicom -t vt100 -M

This sets up a terminal type that is acceptable and makes the Meta key, Alt, work relatively well. Without these things, minicom won’t allow you to exit. Just shut down the telnet session and re-login.


minicom doesn’t seem to change the port very easily. I couldn’t get the serial options to actually change from one modem to the other in one session. The workaround is to have 2 config files that represent each of the modems. These files are called /etc/minirc.whatever whatever defaults to the letter dfl. These should work:

minicom -t vt100 -M modem1
minicom -t vt100 -M modem2

And this too:

vulture:~# minicom -t vt100 -M hp48

This assumes that you are on vulture where there is a hp48 file. The IOPAR variable on the hp48 should be {9600 0 1 1 3 3}
