B: Networking and Security Connect Mode has six variations:  Disabled (no connection)  Enabled (always makes a connection)  Active if it sees any character from the serial port (makes a connection upon receiving any character)  Active if it sees a specific (configurable) character from the serial port  Modem emulation (controlled by modem commands)  Modem control asserted (makes a connection when the modem central signal on the serial line becomes active) For the "any character" or "specific character" connection states, the IntelliBox waits and retries the connection if the connection cannot be made. Once it makes a connection and then disconnects, it does not reconnect until it sees any character or the start character again (depending on the configured setting). Accept Mode In Accept Mode, the IntelliBox waits for a connection. The configurable local port is the port the remote device connects to for this connection. There is no remote port or address. The default local port is 10001 for serial port 1, and 10002 for serial port 2. Accept Mode supports the following protocols:  SSH (IntelliBox is the server in Accept Mode). For this protocol, the SSH server host keys and at least one SSH authorized user must be configured.  TCP  AES encryption over TCP Accept Mode has the following options:  Disabled (close the connection)  Enabled (always listening for a connection)  Active if it receives any character from the serial port  Active if it receives a specific (configurable) character from the serial port (same start character as Connect Mode's start character)  Modem control signal (when the modem control on the serial line corresponding to the tunnel becomes active) IntelliBox-I/O 2100 User Guide 168
