Hi Jens,

It looks like an interesting circuit - maybe you could give an explanation
of how it works - According to Microchip's programming specification Iddp
(PIC Current while Programming) is 20 mA and Ipp (Current sunk at _MCLR
during Programming) is 50 mA.

I'm surprised that an RS-232 port can source this much current.

Good work, I'm interesting in learning more about it.
