RE: Sockets client in RPGIV

You would want to use ACKs (Acknoledgments) if you were using UDP/IP.
UDP is not guaranteed delivery.

Why don't you have this programmer try this.  Have him start sending the
data, then unplug your Ethernet cable and see what his program does.  His
program will generate an error when the packets can't get through.

Thanks for the advice, everyone.  I'm leaning toward implementing this, with
reservations.  The programmer on the other end wants to formally acknowledge
each record ("ok" or "rt"), while I feel that this additional overhead is
unnecessary.  We already had a spec for "send next", which implies that the
record was valid and accepted.  RT would be sent only when we detect a bad
record.  I don't feel that this added complexity adds to the protocol we've
established.

Guess I'd better get busy..... Gotta get this thing delivered Monday. Thanks
again.......
