portKeepalive

Enables a per-connection TCP keepalive feature; after approximately
3 minutes of network connection idle time, the connection will send
a gratuitous ACK to the network peer, either ensuring the connection
stays active OR causing a dropped connection condition to be recognized
by the reverse raw service.
Applications using this feature need to be aware that there might be
some considerable delay between a network disconnection and the port
being available for the next connection attempt; this is to allow any
data sent on prior connections to be transmitted out of the serial
port buffer. Application network retry logic needs to accommodate this feature.
