The Ham Radio Control Library (Hamlib, for short) is a project to provide programs with a consistent Application Programming Interface (API) for controlling the myriad of radios and rotators available to amateur radio and communications users. Many Amateur Radio Transceivers come with serial interfaces that allows software to control the radio. This project will endeavour to provide shared libraries that greatly simplify the application programmer's interaction with radio equipment and other controllable devices such as rotators, switches, etc. The Hamlib Wiki Supported Radios page, https://github.com/Hamlib/Hamlib/wiki/Supported-Radios, contains a snapshot of the supported radios at the time of the last Hamlib release.
