Star Micronics XB24-15 Hexadecimal dump mode, FOR I=0 TO 20 LPRINT CHR$I 30 NEXT 40 LPRINT 50 END

Hexadecimal dump mode

In this mode, all received data will be printed in a hexadecimal dump format, rather than the control codes being acted on as command codes.

This mode is accessed by tuming on the printer, while simultaneously

holding down the ‘+!S‘ and /ME,F!? keys. To turn off the mode, it is necessary to turn off the printer completely.

The printout will be similar to that produced by a MS-DOS DEBUG Display command, ie the hexadecimal values of the bytes received will be given in tows of 16, divided into two blocks of eight. “Unprintable” characters, ie control codes from OOhthrough 1Fh and 7Fh through FFh, are represented by periods.

The following (BASIC) program will produce the result below it:

10 FOR I=0 TO 255

20 LPRINT CHR$(I);

30 NEXT I

40LPRINT

50END

After the program has been run, the printer’s buffer should be flushed by

pressing the i button.
