Control Character 02 . Special keys are located from 00 to 0x1F and characters from 0x80 to

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 AA is required before sending a
label to the host, it could be done by setting three Prefix keys in this way: 0x99 0x41 0x9A.
