Hello!
Im programming an app in Java with a Modem in the serial port.
I already know how to make the app read the messages that the modem sends. Ive also created a thread that after some time, it wakes up and looks if there are messages in the serial port.
BUT, I would be interested in generate an interruption (or an exception, i dont know which is the best choice) that would wake my thread up when there is an incomming message in the serial port from the modem.
That is, the app is asleep (there is no CPU time), and when the Modem sends a message to the serial port, the app would wake up automatically (the interruption will execute a method in the app, or would wake up a thread... i dont know)
Somebody could help me???
Really thank you!
