WiTilt v3 SEN-80563 Question

In the datasheet:

From your base Bluetooth® device, connect to

the WiTilt v3 in serial mode and open a terminal program to which

ever port your Bluetooth® is set to.

Which terminal program? Telnet? How to set port for it? Can somebody give an explanation in details?

Thanks!

I am new with it. Could somebody give any instruction on how to use it? Or some useful links? Thanks.
