The best software that I know is Serial Port Tester by Eltima(test com port). Just read the reviews in google. Features:
1)Collect and record data. Can connect even to a COM port already open by any application to start sniffing it right away.
2) Has a unique functionality of monitoring several COM-ports simultaneously.
3) Read captured data in different ways. There are 4 view modes to present recorded serial data – table, line, dump and terminal.
4) Terminal mode feature enables simulate sending data to serial ports.
5) Full support for Modbus RTU and Modbus ASCII protocols.
