Modbus rtu

Please tell me where to get info on developing a modbus rtu driver for sending data from my ABB plc which speaks modbus rtu protocol and it is a master to my HMI on Linux which is a modbus slave. Or maybe there is a free modbus protocol
for Linux ( if so, where can I get it?). Should I use a special modbus PCI slave card for this kind of application? or I can configure the standard pc serial port as a slave? I will appreciate your reply.

Thank you

matPLC includes a modbus client code in the driver directory. Just download the
weekly tar ball, and it should be in there.
