9.3.2.4. Canceling Command
l
A command which has been entered halfway, entering a backspace code (08H) can cancel a
character or an entered full character string. Parameter “backspace mode” (BM) sets the
cancelling method.
BM0 : a backspace code cancels an entered character string.
BM1 : a backspace code cancels a character.
[When the Handy Terminal FHT11 is used, press the backspace (BS) key.]
1 Parameter “BM1” (Shipping set)
l
For example, when the backspace code is input following VG0.5, the cursor moves one space back
to the position where 5 was input and thereby deletes 5.
