Select or Cancel Automatic Status Back (ASB) (continued)
Exceptions
If n = 0, ASB is disabled.
Unlike the A793, that had a dedicated connector and resultant dedicated status
reporting for each cash drawer, the A794 has a single connector that shares data
reporting from either cash drawer. When either cash drawer is open, an open status
is reported by the printer.
