*Power is "stolen" from the PC's DTR line.  Some PC's (mainly laptops) do
not have enough current to power the interface.  In that case, you may use a
9 volt battery or other 9 to 15 volt source with positive to pin J1 and negative
to J2 or J6.  Also, a few older PC's swapped RX and TX on their serial ports.
