From the developer:
This simulator was originally created around 1999 to allow testing of a driver for a Texas Instruments 500 series controller which I had limited access to while writing the driver. A year latter I re-wrote it to support modbus RTU and TCP, basically because the simulator had allowed me not only to learn the role of master, but also of slave.
