you should really only read one byte at a time. You should wait for that byte 
if it's not the first byte of a packet but you should not wait for it if it is 
the first byte of a packet. You can set the wait timeout fairly high when 
waiting for a non-first byte since you fully expect it to arrive so there's no 
point in setting the itmeout too low and risking missing it.
