Thanks a lot Jeff. At least you cleared my doubt. You mentioned that setting a socket non-blocking can be part of the strategy to use the phone as little as possible for data, leaving maximum amount of time for voice. How is that possible ? Is it by setting a timeout to a very small value ?
Jeff Loucks <[EMAIL PROTECTED]> wrote: The simple answer is, you cannot receive a phone call while actively sending or receiving data. The reason you don't receive your call is that the phone transfers either data or voice, not both. When you have sent or received data, the socket remains in data mode for a time before switching back to voice. This is an optimization for data use. There are ways to shorten the delay from data to voice, but there is always a time when incoming phone calls will be sent directly to voicemail. Setting a socket non-blocking means that a call to NetLib that would otherwise wait for something to happen, will instead return immediately with the error EWOULDBLOCK. It hasn't anything to do with blocking phone calls. However, setting a socket non-blocking can be part of the strategy to use the phone as little as possible for data, leaving maximum amount of time for voice.
