    I plan to use uC/TCP-IP in development of connected device. In the design, it is necessary that some TCP connections remain open for several hours, without exchange of data. Is this possible with uC/TCP-IP?

    Yes, µC/TCP-IP does support keep-alives, the segments commonly used by TCP/IP stacks to keep idle connections open. µC/TCP-IP will transmit keep-alive segments after a configurable interval of idle time on a connection, so that the remote device doesn’t send a FIN segment. For additional details on µC/TCP-IP’s keep-alive features, you can consult Micrium’s blog post on this topic.
