Even if your adapter is generating 13V it wont work as jdm programmer because the software uses bitbang of port pins for programming which cannot be done with usb to serial adapter.

Better go for a usb programmer

Instead using external 13 volts and converting the singal levels, i suggest to build a Pickit2 clone which directly works with the USB port.
