In a "g" protocol environment, I can see that the following could occur:

His receive window is size 3

I send packet 1, then 2, then 3.

He acks packet 1, but I miss the ack due to line noise.

He acks packet 2, and that ack gets through. I'm expecting an ack for 1,
but here's one for 2.
Can I assume that he saw packet 1 OK, because he's just acked packet 2? i.e.
does an ack for packet n count as an ack for all outstanding packets up to n.
