BOOL
Get/Set Protocol probes idle connection (TCP sockets only).
If the Keep alive attribute is set, the connection will be probed for the
first time after it has been idle for 120 minutes. If a probe attempt
fails, the connection will continue to be probed at intervals of 75s.
The connection is terminated after 8 failed probe attempts.
