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. ### Sources - - - - - - - ## Security Notes broad file, network, media, or database tool signal. formula declares a Homebrew service. -
