source    Determines which input sources are allowed. When the IRL V command

returns, source indicates where the data came from. When both keypad and label inputs
are allowed, the source always returns keypad because it is possible for keyed and
scanned data to be intermixed. Although intermixing is possible, it is not likely to occur.

If you have both the keypad and scanner enabled, and you want to know where the data
came from, first check

•  if the symbology is IM_UNKNOWN_DECODE, then the data came from the

keypad.

•  if the symbology is one of the other values (such as IM_CODE_39), then some or

all of the data came from the scanner.

If only the scanner is enabled, then all of the data came from the scanner.
