Typical application scenarios: Watching the TXD and RXD LEDs either changing states or flashing to know data transferring direction: from machine to computer or from computer to machine. Verifying TXD/RXD wires should be wired crossed(swap pin2 and 3) or straight through by observing TXD and RXD LEDs at a rest state. Verifying it is a DTE or DCE device (and whether you need a null modem or not). Verifying whether modem controls are active, even if they're not being asserted. Testing control signal between control systems (AMX, Crestron, etc) and the devices they control. Determining if the serial connection is mated properly and if communications is occurring. Whether the wall control or the projector is malfunctioning.
