Re: [Amforth] Atmega328p

Marc,

I found basically 3 reason for a non-working serial line

- wrong fuse settings. The controller works with a different
  clock as you think it does, which lead to different baud
  rates. The result is some garbage characters on the wire.
  The only solution is to use... the right settings.

- remove the programmer after burning the hex files. Sometimes
  they go crazy and keep the reset pin low -- nothing happens at
  all.

- some atmegas have more than one serial port, ok the 328p has
  only one but check the wiring (again).
