history

Project history and usage

gensio is a C stream I/O framework that gives applications one stackable abstraction over TCP, UDP, SCTP, Unix sockets, serial devices, telnet, TLS, pseudo-terminals, files, sound, and other transports. It also ships command-line tools such as gensiot, gtlssh, gtlsshd, and gmdns.

Project history

The FAQ says gensio began inside ser2net while Corey Minyard was rewriting ser2net to add encryption and authentication. The protocol-layering code became general enough to split into its own library, then grew through additional transports, filters, and proof-of-concept tools.

Adoption history

gensio's adoption is concentrated in systems and networking niches rather than broad application development. The ser2net README describes gensio as a required library and notes that ser2net's crypto, mDNS, IPMI, RFC2217, and command-line connection capabilities come through gensio.

How it is used

Practitioners build gensio stacks as strings, such as layering telnet over TCP or TLS over a transport, and can create outgoing gensios or accepter stacks for incoming connections. The USING guide recommends str_to_gensio and str_to_gensio_accepter for most code, with callbacks for event-driven I/O and blocking helpers for convenience.

Why package nerds care

gensio matters to package users because it turns serial, network, encrypted-login, and remote-console behavior into reusable packaged tools and libraries. It is especially relevant when ser2net-style deployments need authentication, encryption, RFC2217 serial control, or portable I/O behavior across Unix, macOS, BSD, and Windows.

Timeline

  • FAQ: gensio split out of ser2net after its layered protocol code became reusable.
  • 2025: the 3.0.0 release removed deprecated sergensio code after ser2net and language bindings had moved away from it.
  • 2026: the 3.0.2 release notes listed minor fixes across modem, accepter, pcre2, and locking behavior.

Related projects

  • Related tools and protocols include ser2net, gtlssh, gtlsshd, gensiot, RFC2217 telnet serial control, TLS, SCTP, IPMI SOL, mDNS, AX.25, and SoapySDR.
