Hello Berhard, replace speed wit one of the following constants: 300 Baud = 0; 600 Baud = 1; 1200 Baud = 2; 2400 Baud = 3; 4800 Baud = 4; 9600 Baud = 5; 19200 Baud = 6; 38400 Baud = 7; 57600 Baud= 8; 115200 Baud= 9; for example hwcom.setspeed(5); for 9600 Baud speed. because there is no variable named speed. i compiled the rest should be ok . mfg Tom // > Hello Andre > I tried to compile the programme for ASCII-codes and I got the following error messages. > > main (4): unknown identifier "speed" > main (13): unknown identifier "line" > > Could you tell me what the problem is.
