Wavelink Escape Sequence to Disable Scanner

Question

Can Custom Escape Sequences to Disable the Scanner of the MC9090 Running Wavelink VT Emulation Be Sent from the VT Host?

Facts

Custom escape sequences can be sent from a host that will either enable/disable the scanner when using VT emulation.

Answer

The custom escape sequence that needs to be sent from the VT host is as follows:
                   ESC % Pb ; Ps A

Sets the scanner to be enabled/disabled after successful scans, where Pb is the bar code type scanned and Ps is the scanner setting to be set:

• Pb=0  After no scans (Ps ignored); disables mode
• Pb=1  After all scans
• Pb=2  After 1-D bar code scans
• Pb=3  After 2-D bar code scans
• Pb=4  Return current setting (Ps ignored).  Returns:
  • ESC % ? <type> ; <setting> A
• Ps=0  Set mode off
• Ps=1  Set mode on
