Hi Paul,

Yeah you're pretty much there:

1) disconnect the DTR line from your circuit (belt and braces)
2) connect the +ve wire from a 9v DC PSU to pin 1 of the 78L05
3) connect the ground wire from the 9v DC PSU to one of the
regulator's ground pins (I can't read the schematic, there might only
be one ground pin, depends on the package)
4) leave the RXD and GROUND connections to the serial port

cheers

ant
