Automatic TCP connections (Automatic Connection)

The TCP Client allows the Digi ConnectPort X Family product to automatically establish a TCP connection to an application or a network, known as autoconnection. You can enable autoconnection through the TCP Sockets profile’s setting labeled Automatically establish TCP connections. When you set the TCP Sockets profile, the DTR flow-control signal indicates when a TCP socket connection has been established. You can use this information when monitoring the serial line. You can use it as a flow-control mechanism to determine when the Digi device connects to a remote device establishes communication. You can combine this mechanism with the DCD signal to close the connection and the DSR signal to do RCI over serial. Together, you can use these signals to the Digi device to auto connect to many devices, deterministically, on the network.
