TCP Configuration
TCP (Transmission Control Protocol) provides reliable connection-oriented
network communication with error checking. In TCP mode the serial server can
be configured as a client or a server.
When you configure the serial server as a TCP client it initiates connections
with a server on the network. 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.
When the serial server is configured as a
TCP server
it waits for connections
to be initiated by another network device. You must set up the TCP port
number that it will listen to for connections and set the maximum (up to eight)
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.
