+libmodbus is a free software library to send/receive data according to the
+Modbus protocol. This library is written in C and supports RTU (serial) and
+TCP (Ethernet) communications. The functions included in the library have
+been designed with the following properties in mind: easy to use, portable
+(GNU/Linux, Mac OS, FreeBSD, QNX and Windows), high performance, and low
+memory footprint.
+
+The library provides functions to communicate with Modbus devices such as
+PLCs, HMIs, sensors, and other industrial equipment commonly found in
+SCADA and OT/ICS environments.
