COMportit
COMportit is a cross-platform open specification and ecosystem designed to simplify the management and interoperability of communication ports and port-like interfaces across hardware and software. The core concept is the Port Abstraction Layer (PAL), which presents a uniform API for creating ports, attaching transports, exchanging messages, and handling events, regardless of the underlying medium. Supported transports include traditional RS-232/RS-485 serial links, USB endpoints, network sockets, and virtual or tunneled channels. The specification emphasizes asynchronous I/O, pluggable transports, and a security model that covers authentication, encryption, and access control.
COMportit originated from an industry working group and the COMportit Consortium, founded in the late 2010s,
Implementations and usage: Several open-source and vendor-provided stacks implement the PAL and associated APIs. Use cases
Reception: The standard is praised for its unifying abstraction and portability benefits, but some observers note
Status: As of 2024-25, the COMportit ecosystem includes multiple implementations, ongoing transport extensions, and evolving security
