I have now installed mingetty and mgetty but I have no clue on how to
use these programs. If I run mingetty from an X11-console it lets me
enter characters but nothing else, no matter what I specify for
--loginprog. If I do a mingetty /dev/tty7 I can enter a few characters
on that terminal before mingetty terminates.

Typically, you run getty on one computer (the host), then screen (or
some other terminal emulator) on the second.
getty will prompt you for a login/password and then spawn a shell.
I suppose you could just spawn a shell directly (from systemctl), but
that is, obviously, insecure.
Ultimately, what you're seeing is an issue with canonical processing.
The "host" of the connection usually "echos" back each character sent to it.

Dear maintainers of screen
Today I wanted to connect two machines using screen:
machine1> screen /dev/ttyS0
machine2> screen /dev/ttyUSB0
The problem about it is that \n does not go to the beginning of
a new
line but merely one line below without carriage return. I have tried to
set onlcr with stty but that does not help. Also I have played with
TERM=putty and screen.putty but could not resolve the issue.
I have discovered the same issue with
machine1> screen /dev/ttyS0
machine2> echo hugo >/dev/ttyUSB0
The goal would of course be to run bash on one computer and
screen on
the other:
machine1> screen /dev/ttyS0
machine2> TERM=screen.putty bash </dev/ttyUSB0 >/dev/ttyUSB0
2>/dev/ttyUSB0 & echo $!
Same problem here: '\n' does not do an additional carriage
return as
required.
Anyone here who can help me?
