Tunnel – Accept Mode
Controls how a tunnel behaves when a connection attempt originates from the network. 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 increases sequentially for each additional serial
port, if supported.
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
To configure the tunnel’s Accept Mode:
1. Click
Tunnel > Accept Mode
at the top of the page. The Tunnel 1 Accept Mode page
appears.
Note:
The
CP Output
option displayed in the screenshot is only supported in XPort Pro
and XPort AR.
