You can force that. An application can force delivery of segments to the output stream using the push operation provided by TCP and setting the PSH flag to ensure that data will be delivered immediately to the application layer by the receiving transport layer. This is how telnet sends single keystrokes, for example.



That's an interesting point Marshall .. in fact, you seem to have explained just "how Telnet does it," which is great.


(Perhaps that technique is enough to solve Thomas' problem at hand?)

What are the actual methods or code used in a Mac or iFone milieu for these "push operation and the PSH flag" thingies of which you speak?


Signed, Networking Curious :)
