Hello
I am trying to read via the serial port. With a key span adapter but It isnt working this is the code I am using to test.
char val ;
void setup() {
beginSerial();
}
void loop() {
// Set the background to the value in val
}
void serialEvent() {
// Initializes the variable val with the
// last value readed by the serial port
val = (char)serial;
println(val);
}
any ideas?

port in use probably means that you've got isync, or palm desktop's hotsync app, or some sort of gps software that's holding onto the serial port and preventing processing from getting access to it.

I dont have isync running at the same time as processing but I do have it as an application , is there away to get it to "let go" of the port? There isnt any gps software so it seems that isync is the only source of irritation 
cheers
