Yes, I do know what the problem is. What you need to do is to pass an extra 
boolean parameter to each of your input handlers to instruct it to wait or to 
not wait for the next byte. This boolean should be set to false (don't wait) 
for the first byte of a packet, but to true (wait) for any of the rest of the 
bytes of a packet. Right now you can have the situation where it doesn't wait 
even though it's in the middle of a packet and the rest of the bytes haven't 
arrived yet.
