Start a wrapper emulating Soviet 15IE (see footnote 1) terminal:

Using a keyboard and a screen attached to the MiSTer device launch MC1201 core, open OSD and switch "Console:" to "Console: UART". You may want to set "CPU slow:" to "ON" if you plan on running a game.

Start GNU screen to [indirectly] handle ancient KOI7 (vtwrap can translate KOI7 into more or less supported KOI8, which will be translated into your actual termial's locale by GNU screen). Note: this is not the only way to do it, but I find it easy (and it keeps your SSH session alive as well).

debian$ vtwrap -t 15ie

Some MiSTer console output will look weird, just ignore it.

SSH to the MiSTer:

debian$ ssh root@mister

set uartmode to "2" (1 - ppp, 2 - serial console on ttyS1, 3,5 - midilink):

/root# uartmode 2

make sure the mode is set up properly (from time to time MISTer may reset it):

/root# uartmode

you should see the following, if you do not, re-run "uartmode 2"

ttyS1: 115200

launch picocom (microcom seems to be working with vtwrap, does NOT without it), picocom defaults to 9600 baud, so specifing correct line speed is essential:

/root# picocom -b 115200 /dev/ttyS1

exit picocom when needed with C-a a C-x

At this point you better turn on CAPS LOCK as most of the commands are uppercase (lowercase English letters are mapped to Cyrillic when using KOI7)
