Development files for libmodbus
libmodbus is a C library designed to provide a fast and robust implementation of
the Modbus protocol. It runs on Linux, Mac OS X, FreeBSD, QNX and Windows.
This package contains libraries, header files and developer documentation needed
for developing software which uses the libmodbus library.
