Escape Commands
The Cordless System will respond to beep and blink commands from the host
system. The format for these commands is:
y Esc x , where “y” is the Application Work Group number and “x” is one
of the Escape commands listed below. A comma must be used to terminate the
command. The table below lists the Escape commands that must be generated
from the host system and the resulting action(s).

Note: Host ACK mode will only work with a host system that supports RTS/CTS
flow control. If your host system does not support RTS/CTS handshaking,
turning on Host ACK selection will cause some or all of your data to be lost.
This selection programs the Cordless System to wait for a confirmation signal
(ACK) from the host after bar code data has been sent. When Host ACK is turned
on, the host system must be programmed to generate Escape Commands (see
section below) for user feedback. Page 1–13 in the Getting Started Section
explains how Host ACK works and provides an illustration of the feature.
Host ACK mode is designed to respond to a specific Application Work Group
(see Section 4 for more information on Work Groups); the host system issues an
Escape sequence to
all scanners in the Work Group. Up to twenty Escape
commands may be strung together to create custom beep/blink sequences.
An example of an Escape string to create a “low, medium, high” beep sequence
for scanners in Application Work Group 2 would be: “
2esc4esc5esc6,”. The first
character indicates the Work Group and the comma is used as the delimiter. If
it can’t be determined that the data has been properly sent to the host system,
the scanner issues 4 beeps (low, high, low, high tones). You must then check
to see if the scanned data was received by the host system.
Note: Host ACK may be used with Decode Beep Selection (see page 4–4).
