7: Line and Tunnel SettingsPremierWave® EN Embedded System on Module User Guide 74Table 7-5 Tunnel Accept Mode SettingsTunnel Accept ModeSettingsDescriptionModeSet the method used to start a tunnel in Accept mode. Choices are: Disable = do not accept an incoming connection. Always = accept an incoming connection (default). Any Character = start waiting for an incoming connection when anycharacter is read on the serial line. Start Character = start waiting for an incoming connection when the startcharacter for the selected tunnel is read on the serial line. Modem Control Asserted = start waiting for an incoming connection aslong as the Modem Control pin (DSR) is asserted on the serial line until aconnection is made. Modem Emulation = start waiting for an incoming connection whentriggered by modem emulation AT commands. Connect mode must also beset to Modem Emulation.Local PortSet the port number for use as the network local port. The default local portnumber for each supported serial line number progresses sequentially inequal value so that Tunnel X: 1000X. For example: Tunnel 1: 10001 Tunnel 2: 10002 Tunnel 3: 10003Protocol Select the protocol type for use with Accept Mode: SSH SSL TCP (default protocol) TCP AESNote: TelnetCredentials Specifies the name of the set of RSA and/or DSA certificates and keys to beused for an SSL connection.AES Encrypt Key Specify the text or hexadecimal advanced encryption standard (AES) key forencrypting outgoing data for a TCP AES connection.AES Decrypt Key Specify the text or hexadecimal AES key for decrypting incoming data for aTCP AES connection.TCP Keep Alive Idle Time Enter the time, in milliseconds, the PremierWave EN module waits during asilent TCP connection before checking if the currently connected networkdevice is still on the network.TCP Keep Alive Interval Enter, in milliseconds, the amount of time between two successive keep aliveprobes if no acknowledgment to the previous keep alive probe is not received.TCP Keep Alive Probes Specify the number of TCP Keep Alive probes (after the TCP Initial KIeepAlive probe) to send before closing the connection if no response is received.Valid values are between 1 and 16.
