14 Tunneling
Accept Mode
In Accept Mode, the XPort Pro waits for a connection from the network. 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 (the XPort Pro is the server in Accept Mode). When using this protocol, the SSH server host keys and at least one SSH authorized user must be configured.
SSL
TCP
AES encryption over TCP
Telnet (The XPort Pro supports IAC codes. It drops the IAC codes when Telnetting and does not forward them to the serial port).
Accept Mode has the following states:
Disabled (never a 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
Modem emulation
Disconnect Mode
Disconnect Mode ends Accept Mode and Connect Mode connections. When disconnecting, the XPort Pro shuts down connections gracefully.
The following settings end a connection:
The XPort Pro receives the stop character.
The timeout period has elapsed and no activity is going in or out of the XPort Pro. Both Accept Mode and Connect Mode must be idle for the time frame.
The XPort Pro observes the modem control inactive setting.
Note: To clear data out of the serial buffers upon a disconnect, enable “Flush Serial Data”.
