This DeltaProg is some 3rd party software. It is restricted to COM1 RS232 serial port.
There are a number of parallel burners I have found, but awful software.
I have been using DeltaProg as it will make a code plug file I use for hacking.
Yea, I ran across that emulator and the price is double that suitcase programmer from GE.
Sort of made one of those years back from a credit card terminal. working on much the same now with improvements. (include CTCSS/DCS)
Back in the day, seems I had a prom burner that could do the X2212, I know it could do the 8049, that is how I fudged the Delta firmware. Needham's PB10 I think.
Been looking for a s825, but I think that RS232 programming is with the suitcase programmer.
The radio can program from the front plug.
These are old boat anchor door stops, but built like a tank, easy to mod and good as any today's radios.
I suppose I could engineer my own programmer, hoping for some shortcuts.
