ON PORTIN

This command allows a Fingerprint application to detect in
signals. If a particular in signal is asserted, the application moves
to the subroutine responsible for carrying out tasks related to that
in signal. One command is available for detection of each of the 8
in signals.
This command is not supported by the Intermec Direct Protocol.
Example
ON PORTIN.STARTPRINT GOSUB nnn

PORTIN

This command is a version of the PORTIN(PORT) command
and checks the current state of a specified signal. This command
returns -1 if the signal is asserted, or 0 if the signal is de-asserted.
This command is supported by Fingerprint and Direct Protocol.
Examples
PORTIN.STARTPRINT
or
PORTIN.RIBBONLOW

PORTOUT

Supports manually modifying the dataready signal. PORTOUT
is not allowed when the applicator port style is set to S-Style.
This command is not supported by Direct Protocol.
Example
PORTOUT.DATAREADY ON
PORTOUT DATAREADY OFF
where on asserts the dataready signal low and off de-asserts the
dataready signal high.

ON PORTOUT

This command allows a Fingerprint application to detect when
out signals have been reset to default values. The command
moves to a specified subroutine whenever the applicator port
status is enabled, and whenever the applicator port style is
changed.
Example
ON PORTOUT.RESET GOSUB nnn
