Element Description
<meta http-equiv = "ExitBusApp" content="yes"/>
This meta tag causes the business application to exit and the UCA
client application goes back to the UCA client application desktop.
This means the user is still logged in and has access to the
menus, walkie-talkie or phone calls.
<meta http-equiv ="scanner" content="[parameter]">
Parameters:
enabled- Enables the scanner.
disabled- Disables the scanner.
autoenter- Automatically appends a carriage return to the end of
any bar codes scanned.
autotab- automatically appends a tab to the end of any bar
codes scanned.
This meta tag allows the business application developer to enable
or disable the scanner as well as append a carriage return or tab
to the end of the scanned label.
Note: The enable and disable parameters are only necessary
when the business application developer wishes to use the
custom "scannernavigate" meta tag.

This custom tag allows scanner data to be passed back up to the

Retrieval tags return information by replacing the text '%s' within

in sequence for that for the amount supplied. For example:

content="PriceLookup.htm?label=%s;source=%s;typ
e=%s;time=%s;length=%s" />
