In the Users / Handheld section, there is a server to client heartbeat. Does this function as a keep-alive? Our network guys are timing out sessions to quickly and we need to keep the sessions alive.

Hello,

The Server Heartbeat is not a keepalive. Actually it is the opposite. It is an orphan cleanup feature. It detects if the device has shutdown, then closes the session. If your device does not support the mid-session telnet protocol exchange, then it could close sessions down unexpectedly. 

Please check the Event Viewer under Windows Applications and Services Logs -> Pragma TelnetServer for an information event that we shut down due to a lack of response to a server heartbeat.

So, there isn't a keep-alive feature, correct?

No we do not have a keep-alive feature. You might see if the handheld has something that will keep the session active.
