Oh if it were that simple :)
I believe this has been discussed before at greater length than I have
the knowledge to repeat but the summary is:
1) Your application may not be able to get the TCP/IP state directly
enough from the stack to know about failures.
2) Your TCP/IP stack, or your provider's, may be neutered such that
the ACKs don't mean anything useful anyway.
3) You might be using a different transport.
