OK, I've been using PICAXEs for a while, but have always used header connectors on the PICAXE end. I have a project where I want to use the 1/8" phone jack for external programming of a PICAXE in a metal box. I went back the Manual #1...page 8. I was surprised to see that the "barrel" connection is Serial-out and not Common. In most all other electronics wiring the phone jack barrel is common/ground. Is there a reason?...like preventing shorting specific connections as the plug is inserted or withdrawn from a live serial-port to a live PICAXE.
A quick "search" turned up way too many threads about serial cables.
