Also, thanks for the suggestion, but WCF isn't an option here. The keepAliveTime parameter specifies the timeout, in milliseconds, with no activity until the first keep-alive packet is sent. By sending Keep Alive packets, you can learn about Telnet connection problems as they occur and avoid losing entered data. In this video, we will use Wireshark to examine TCP Keep Alive behavior. > number that is nonincrementing to determine if in fact the packet is a > keep-alive packet? I'm not sure how the keep-alives are detected without looking at the code. Keepalive can tell you when another peer becomes unreachable without the risk of false-positives.
