I have a KEIL MCBx51 board with a P89C662 chip on it. I downloaded FlashMagic. I am trying to use it to FLASH a HEX file into the chip but I am unable to connect. Do I need to set the board or the chip in a certain way for FlashMagic to connect. I have tried changing the baudrate in FlashMagic with no luck
