Im getting frustrated with my electronic knowledge, because I want to do this simple thing:

Olimex 328/ATMega328 reads data from UART (Olimex MOD-PULSE or whatever) and forwards it to the USB Port (my computer).

I dont understand how I can do this, I wrote following programm

void setup()         // run once, when the sketch starts
{
  Serial.begin(9600);
  Serial1.begin(9600);
}

void loop()                       // run over and over again
{
  Serial.println(Serial1.read());  // prints hello with ending line break 
}

But it doesnt work, since Serial1 is not existing.. Could you give me a hint? I dont find anything understandable (for me) in the internet... Thanks!
