# http://tinker.it/now/2007/02/24/the-tale-of-avrdude-atmega168-and-extended-bits-fuses/
#
# similarly, the lock bits should be 0xff instead of 0x3f (to
# unlock the bootloader section) and 0xcf instead of 0x0f (to
# lock it), but since the high two bits of the lock byte are
# unused, avrdude would get confused.

* Udp.cpp: Library to send/receive UDP packets.
*
* NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
* 1) UDP does not guarantee the order in which assembled UDP packets are received. This
* might not happen often in practice, but in larger network topologies, a UDP
* packet can be received out of sequence.
* 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
* aware of it. Again, this may not be a concern in practice on small local networks.
* For more information, see http://www.cafeaulait.org/course/week12/35.html
