19 * TODO: Added a try catch block in sendPacket to avoid an execption in case the PHP script
20 * has finished and DBG isn't ready for receiving any new frame.
21 * (This happens when mouse is hovering over variable or user switches to watch expression)
22 * It is not clear why DBG isn't sending any SCRIPT_END event (or something similar),
23 * or whether there is another way to check whether DBG is listening or not.
24 * For the moment this is only a workaround.
