Regards the timeout, there is not else you can do but catch the exception and keep going. But you will might have trouble if you try to send fewer bytes than is available in the device pipe buffer. Try to read at least one packet size bytes. -- Best Regards, Wander Lairson Costa ------------------------------------------------------------------------------ Ridiculously easy VDI.
