Disable Output
Note:
Control code (0x01 ~ 0x1A) can be sent by two methods:
(1) Ctrl Mode:
A barcode of “A<HT>F” (0x41/0x09/0x46) is scanned, the output sequence is:
a. Enter “A” – Press A key
b. Enter “Ctrl + I” – Since 0x09 corresponds to “CtrI + I”, virtual keyboard will press and hold
Ctrl key, press I key, and release Ctrl key and I key
c. Enter “F” – Press F key

MT8250P User’s Manual V1.3

Since “Ctrl+I” is shortcut for italicizing text in some software applications, the result of above
output sequence can be a regular A plus an italic F.
(2) Alt Mode:
For <HT>, the output sequence of virtual keyboard is:
Enter “Alt + 0 + 0 + 0 + 9” – Virtual keyboard will press and hold Alt key, press “0”, “0”, “0” and
“9” on numeric keypad respectively, and release Alt key.
