The original keycodes are replaced in sequence with the 32 bytes following the "u".

The keycodes, liked the fixed texts, are permanently stored in EEPROM.

Example:

PRINT #1,CHR$(27);"&u";

TEXT$ = "abcdefghijklmnopqrstuvwxyz,.;:?"

L = LEN(TEXT$)

FOR I=1 TO L

NEXT I

ESC & P n

This command sets the keyboard operation mode:

n=0

Polling mode: the code of the last pressed key is only sent when requested and

only when this command has executed. If no key was pressed since the last query,

MiniTerminal outputs the code 255 / FF

n=1

keycode is sent automatically when key is pressed, even if the key is kept pressed.

n=2 ..7

Autorepeat mode: the keycode is sent as long as the key is pressed, ending when

it is released. Various speeds can be set based on n:

2 : very quick to 7: approx. 2-second frequency

On power on, Autorepeat mode, level 2, is activated.

Example:

PRINT #1,CHR$(27);"&P0";

PRINT #1,CHR$(27);"&P5";

PRINT #1,MID$(TEXT$,I,1);

R$ = INPUT$(1,#1)

IF R$ <> MID$(TEXT$,I,1) THEN GOTO error

PRINT "Error while saving"
