libserialport (sometimes abbreviated as "sp") is a minimal, cross-platform shared library written in C that is intended to take care of the OS-specific details when writing software that uses serial ports.

It is licensed under the terms of the GNU Lesser General Public License, version 3 or later.

Note: While libserialport is hosted on sigrok.org (and sigrok uses libserialport), this is a completely independent library that can be used by other projects as well. The libserialport library does not depend on any sigrok related libraries or projects.
