Virtual Keyboard
1. Control Code Output Methods
Control code (0x00 ~ 0x1F) can be sent by two methods:
Ctrl Mode*
Alt Mode
2. Control Code Output
The ASCII between 0x00 to 0x1F can be transformed into control code.
When virtual keyboard is enabled, the output sequence of control code 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
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.
Please note that Ctrl Mode is only supported by English (USA) keyboard
layout.
(2) Alt Mode:

control code output will be ALT + ASCII Decimal Value. For <HT>, the
