I am using select() API to polling on it. I get notification in this case, but if I do not read the data or reading handling thread is busy, then also it keeps giving notification that data is there. I want to get the notification only when there any new event happen or new data comes. Eli _______________________________________________ Do not post admin requests to the list.

Please suggest me to resolve the issue. Keep track of it yourself then. Set a flag in your own code when select() tells you the serial port has data that your 'worker' thread checks/clears before it goes idle, then stop passing that port to select() until your worker thread clears that flag. Waking up select() to re-add the port when the worker thread goes idle is left as an exercise for the reader. This email sent to site_archiver@lists.apple.com
