I like convenience as much as anyone but sometimes I just have to get on with it. Does anyone have experience in communicating with really simple machines over a serial connection? It's not always easy to ID the serial device but that's a separate problem. Allegedly I can communicate up to 115k but I'll settle for a lot less to send simple commands like M502 or M500.

cu -l /dev/cuaU0 -s 115200 ?
minicom ?

man cu
man minicom

make sure your user is in the dialer group in order to access serial
port device.

you may want to first run `minicom -s /dev/cuaU0` as root in order to
setup the port configuration file, then as user just `minicom
/dev/cuaU0`.

assuming your device shows up as /dev/cuaU0.

have fun :-)
