Activating One Communications Protocol
A COM port can only use one communications protocol at a time. You
designate the communications protocol that a port will use when you activate
the communications protocol. You must activate one communications protocol
for the COM port.
To activate one communications protocol for a COM port
• Execute the Communications Protocol, Activate command to activate the
communications protocol. For help, see “Communications Protocol,
Activate” in Chapter 12.
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 a third-party 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 third-party software.
