Data is routed to the serial device connected to the Digi device's serial port. The network is transparent to both the
application and the serial device.
Important: On each computer that will use RealPort ports, RealPort software must be installed from the Digi Support
site or the Software and Documentation CD, if provided with the Digi device, and then configured. Installation
instructions are on page 70. type the IP address of the Digi device and the RealPort TCP port number 771.
Console Management profile
The Console Management profile allows access to a device's console port over a network connection. Most network
devices such as routers, switches, and servers offer one or more serial ports for management. Instead of connecting a
terminal to the console port, cable the console port to the serial port of the Digi device. Then using telnet features,
network administrators can access these consoled serial ports from the LAN by addressing the appropriate TCP port.
TCP Sockets profile
The TCP Sockets profile allows serial devices to communicate over a TCP network. The TCP Server allows other
network devices to initiate a TCP connection to the serial device attached to the serial port of the Digi device.
Automatic TCP connections (autoconnection)
The TCP Client allows the Digi device to automatically establish a TCP connection to an application or a network,
known as autoconnection. Autoconnection is enabled through the TCP Sockets profile's setting labeled
Automatically establish TCP connections. When the TCP Sockets profile is set, the DTR flow-control signal indicates
when a TCP socket connection has been established. This information can be useful in monitoring the serial line and
using it as a flow-control mechanism to determine when the Digi device is connected to a remote device with which
communication is being established. 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 auto connect to many
devices, deterministically, on the network.
