Loading and Unloading a Protocol Handler
You can load protocol handlers in several ways:
• Manually load them at the DOS prompt.
• Load them from AUTOEXEC.BAT when you boot the reader.
• Include them in a batch file that also executes your program.
• Load them when you start IRL Desktop or Communications Manager.
Note: A protocol handler is active when its corresponding communications protocol is
active. For example, if the PC Standard protocol handler is loaded, it will not become
active until you use the Communications Protocol, Activate command to activate the
PC Standard protocol.
If you are using an off-the-shelf communications application that directly
accesses the COM port, do not load a protocol handler. Instead, activate No
Protocol in the reader’s configuration. You cannot download reader
configuration commands from the host computer when using off-the-shelf
software.
Loading and Unloading a Protocol Handler at the DOS Prompt
You can load the protocol handlers from the DOS command line. You should
unload the protocol handler when you are finished to maximize memory.
To load a protocol handler
• Type this command at the reader’s DOS prompt:
protocol_handler port
where:
protocol_handler is the protocol handler you are loading:
PHIMEC Intermec protocol handler
PHPCSTD PC Standard protocol handler
RFPH RF protocol handler
port is the number of the COM port for which you are
loading the protocol handler.
