javax.comm.CommPortIdentifier

Communications port management. CommPortIdentifier is the central class for controlling access to communications ports. It includes methods for:

Determining the communications ports made available by the driver.
Opening communications ports for I/O operations.
Determining port ownership.
Resolving port ownership contention.
Managing events that indicate changes in port ownership status.

An application first uses methods in CommPortIdentifier to negotiate with the driver to discover which communication ports are available and then select a port for opening. It then uses methods in other classes like CommPort, ParallelPort and SerialPort to communicate through the port. @author Jagane Sundar @version 1.11, 23 Jan 1998 @see javax.comm.CommPort @see javax.comm.CommPortOwnershipListener @see javax.comm.ParallelPort @see javax.comm.SerialPort
