Windows device driver information for HP communications port

A communications Port refers to software which is specific to a particular application or process. It serves as a communication endpoint and is used by the Internet Protocol Suite's transport layer protocols. These protocols can be either the Transmission Control Protocol (TCP) or the User Diagram Protocol (UDP). A port is usually identified through a specific number that is referred to as the port number. It is also identified by the IP address linked to it as well as the protocol that is utilized for communication. Communication ports are also referred to as Com ports or serial ports. They are usually rounded in structure whereas the parallel ports are flat and are referred to as LPTs. Users should note that a parallel port is different from a serial port and the serial port is the one referred to as the communication port.
