| Tunnel Accept Mode |
| Description |
| Settings |
|
|
| Mode |
| Set 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 any |
|
|
| character is read on the serial line. |
|
|
| Start Character = start waiting for an incoming connection when the |
|
|
| start character for the selected tunnel is read on the serial line. |
|
|
| Modem Control Asserted = start waiting for an incoming connection as |
|
|
| long as the Modem Control pin (DSR) is asserted on the serial line until |
|
|
| a connection is made. |
|
|
| Modem Emulation = start waiting for an incoming connection when |
|
|
| triggered by modem emulation AT commands. Connect mode must |
|
|
| also be set to Modem Emulation. |
|
|
|
|
| Local Port |
| Set the port number for use as the network local port. The default local port |
|
|
| number for each supported serial line number progresses sequentially in |
|
|
| equal value so that Tunnel X : 1000X. For example: |
|
|
| Tunnel 1 : 10001 |
|
|
| Tunnel 2 : 10002 |
|
|
|
|
| Protocol |
| Select the protocol type for use with Accept Mode: |
|
|
| TCP (default protocol) |
|
|
| TCP AES |
|
|
| Telnet |
|
|
|
|
| TCP Keep Alive |
| Enter the time, in milliseconds, the XPort Pro Lx6 waits during a silent TCP |
|
|
| connection before checking if the currently connected network device is |
|
|
| still on the network. If the unit gets no response after 1 attempt, it drops |
|
|
| the connection. Enter 0 to disable. |
|
|
|
|
| Flush Serial |
| Set whether the serial line data buffer is flushed upon a new network |
|
|
| connection. Choices are: |
|
|
| Enabled = serial data buffer is flushed on network connection |
|
|
| Disabled = serial data buffer is not flushed on network connection |
|
|
| (default) |
|
|
|
|
| Block Serial |
| Set whether Block Serial is enabled for debugging purposes. Choices are: |
|
|
| Enabled = if Enabled, incoming characters from the serial line will not |
|
|
| be forwarded to the network. Instead, they will be buffered and will |
|
|
| eventually flow off the serial line if hardware or software flow control is |
|
|
| configured. |
|
|
| Disabled = this is the default setting; incoming characters from the |
|
|
| Serial Line are sent on into the network. Any buffered characters are |
|
|
| sent first. |
|
|
|
|
| Block Network |
| Set whether Block Network is enabled for debugging purposes. Choices |
|
|
| are: |
|
|
| Enabled = if Enabled, incoming characters from the network will not be |
|
|
| forwarded to the Serial Line. Instead, they will be buffered and will |
|
|
| eventually flow off the network side. |
|
|
| Disabled = this is the default setting; incoming characters from the |
|
|
| network are sent on into the Serial Line. Any buffered characters are |
|
|
| sent first. |
