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 OOh through 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
40 LPRINT
50 END
After the program has been run, the printer's buffer should be flushed by
pressing the i
button.
