  The simple serial interface works fine if you talk about the wloader
interface. Just with minor adjustements was tested on many ( really many!)
computers, cable lenght up to 1m . Redesign with any serial interface is
not a problem. ( max232-very expensive, GD75232-difficult to obtain, or
even 1488/1489 -the cheapest, but a +/- supply is requested, so one more
pic pin must be free for oscillator )
