This section will introduce some examples to control the DIO lines of
this Adapter. We are using a Terminal Emulation Program (such as
HyperTerm or TeraTerm) to send control strings over the TCP/IP socket
port.
HyperTerm is a Windows based utility for Windows XP or earlier version.
However, it is not bundled in Vista or later Windows version.
As shown in the HyperTerm examples, the application software can
read or write the string (in ASCII code format) on the TCP/IP socket
port to check or change the Adapter’s state.
