Setting up Paired Mode Operation
Paired Mode enables two serial servers to operate across the network like a
"wire replacement" between two serial devices. (Paired Mode is also called
serial tunneling.) Serial devices connected to serial servers on each end of the
link can communicate as it they were connected by a serial cable.
For Paired Mode to work one serial server must be configured as a TCP server
and the other as a TCP client.
The serial server configured as the TCP client initiates the connection. You
must set up the IP address and port number of the server that you want the
client (serial server) to communicate with. You also select whether you want
the serial server to connect at power up or only when it receives data from the
device connected to its serial port.
The serial server configured as a TCP server waits for connections to be
initiated by another network device. You must set up the TCP port number on
which it will listen for connections and set the maximum (up to four) number
of simultaneous connections it will accept. You can filter the connections it will
accept based on specific IP addresses or ranges of IP addresses that you
specify.
