Each of these ports may be configured to provide +5V or +12V output to Pin 1 or Pin 9 to power your serial port

peripherals. They must not be setup to provide power to Pin 1 and Pin 9 simultaneously. Do not hot plug onto

a COM port configured to provide power to pin 1 or pin 9. You run a risk of shorting the powered pin to the

port’s shield while hot plugging. By default, COM2, COM3 and COM4 have +5VDC on pin 9.
