Ola amigos
Possuo uma aplicação que faz comunicação com varias portas seriais e pra isso utilizo varias classes de comunicação que utilizão o API RXTXcomm 64bits.
Exemplo da conexão de cada classe:
public int send () throws Exception{
app.main.ocupado2 = 1;
SerialParameters params = defaultParameters;
mySerial =new SerialConnection (params);
mySerial.openConnection();
aThread=new Thread(this);
aThread.start() ;
return 0;
}[/code]
Estou tendo o seguinte erro após um tempo de operação:
[size=7][code]
