Scancode Tables

Control Character Emulation

Control character emulation selects from different scancode tables as listed

in this appendix. Each of the control character sets below are detailed by

interface type in the tables. These apply to Wedge and USB Keyboard

platforms.

Control Character 00 :

Characters from 00 to 0x1F are sent as control character

Ctrl+Keys, special keys are located from 0x80 to 0xA1.

Control Character 01 :

Characters from 00 to 0x1F are sent as control character

Ctrl+Capital Key, special keys are located from 0x80 to 0xA1.

Control Character 02 :

Special keys are located from 00 to 0x1F and characters

from 0x80 to 0xFE are intended as an extended ASCII table (Microsoft

Windows Codepage 1252 — see page 311).

Single Press and Release Keys

In the following tables, Ar↓ means Alt right pressed and Ar↑ means Alt right

released and so on. Definitions for other keys are Al (Alt left), Cr (Control

right) Cl (Control left) Sh (Shift). This method can be used for combining Alt,

Control or Shift with other keys.

Example

Consider a Control character set to 00. If AltRight+A is required before

sending a label to the host, it could be done by setting three Prefix keys in

this way: 0x99 0x41 0x9A.
