42 CHAPTER 3: CONFIGURING THE ETHERNET ADAPTER
Serial Port Under System Configuration, click Serial Port to set up network serial port
operation.
About UART
A Universal Asynchronous Receiver/Transmitter (UART) is the fundamental
hardware for serial communication, controlling the speed and method of
data transfer of the serial port.
Applications utilizing a network serial port between an RS-232 interface and
a wireless device use a TCP/IP socket connection. Any program that uses standard
TCP/IP network sockets may be used to communicate with the serial port of the
Ethernet Adapter. Once a socket is established to the Ethernet Adapter, any data
written to the socket is sent out the serial port of the Ethernet Adapter. At the
same time, any data received by the serial port of the Ethernet Adapter is returned
via the socket connection. The serial port communicates to the wireless port only.
The serial port cannot communicate with the wired Ethernet port.
The Ethernet Adapter network serial port may be used in two modes:
■ Server Mode — TCP Listen Port
■ Client Mode — TCP Connect Port
In Server Mode, the Ethernet Adapter waits for a TCP/IP socket connection
to be made over the wireless port by the network program with which it
will communicate. Server mode should be used if you have a central server
that expects to open a TCP/IP socket connection to the Ethernet Adapter.
In Client Mode, the Ethernet Adapter establishes socket connection over
the wireless port to the IP address and port number specified in the
configuration. Client mode should be used if your system expects the
Ethernet Adapter to open a TCP/IP socket connection to a central server.
Configuring Operation Mode
Attach your computer to the serial port on the Ethernet Adapter, and
then configure the Ethernet Adapter through the computer.
■ Select Enable to establish a TCP/IP socket with a remote computer in
either infrastructure or ad-hoc mode. This allows you to do data
communication with the remote computer.
■ Select Disable to disable the Network Serial Port.
