Once chosen and restarted check
code {
font-family: Consolas,"courier new";
color: crimson;
background-color: rgba(0, 0, 0, 0.2);
padding: 2px;
font-size: 105%;
}
dmesg for activated serial consoles. They probably pop up as devices like
code {
font-family: Consolas,"courier new";
color: crimson;
background-color: rgba(0, 0, 0, 0.2);
padding: 2px;
font-size: 105%;
}
/dev/ttyS1 and so on.
