    MemberDescription
    KeepAliveNoneNo keep alive packets are sent to the host.
    KeepAliveNOPA No Operation (NOP) command is periodically sent to the host. The gateway and host are not required to respond to these commands, but the TCP/IP stack can detect if there was a problem delivering the packet. Use KeepAliveTimeout to control the interval between requests.
    KeepAliveSystemThe TCP/IP stack keeps track of the host connection. This value requires less system resources than KeepAliveTimingMark or KeepAliveNOP, but most TCP/IP stacks send Keep Alive packets infrequently.
    KeepAliveTimingMarkA Timing Mark Command is periodically sent to the host to determine if the connection is still active. The gateway or host should respond to these commands. If InfoConnect does not receive a response or there is an error sending the packet, it shuts down the connection. Use KeepAliveTimeout to control the interval between requests.
