Adjusting the scancode set of a PS/2 keyboard
If a key is pressed on the PS/2 keyboard, the keyboard processor sends a data packet
that is called scan code. The two common scan code sets (sets 2 and 3) contain dif-
ferent scan codes.
The user module interprets all inputs of the PS/2 keyboard with scan code set 2.
If the pipe (“|”) cannot be entered or if the arrow keys of the keyboard do not work
as expected, it is recommended to switch to scan code set 3.

1. Press the
Alt+Num
