We can use any tools sending test string for simulating serial port
transmission. If the SST-900B external switch in the correctly position, we can
use the SST-900B like a real wire.
When the SST-900B sending any wireless signal, the green LED indicate will
be blinking, and so is the yellow LED indicate receiving data.
