HCS12 SMP

it seems there is some kinda 2k program that can read, write, and program the uC through the serial line. its talked about in AP2548. seems interesting. according to the aplication note there is no way to destroy the program without a real BDM ... famous last words I'm sure. so, all I gotta do is attach the serial port of my PC at 115kbaud and see if I get a prompt!
