You can attach your phone to your PC to send and
receive SMS messages through an Infrared connection. Most mobile
phones have IR ports, and notebook computers are also equipped
with it. An Infrared connection is a good option if
you want to use Ozeki NG - SMS Gateway for short periods to send and
IR ports cannot be used to establish long-lasting
connections between the phone and the PC for two main reasons.
There must be a line of sight between the two communicating parties, which is
often broken if one of the devices is moved. The other problem is the
way IR connectivity is implemented in GSM phones. Very often, phones switch
off their IR port after a certain period (e.g. 10 minutes)
If you choose to use Infrared (IR), you must enable
your infrared port on the phone. (Sometimes you have to turn it on in
the PC as well). When this is done,
you should place the phone within range of the IR receiver on the PC. When
the PC and the phone begin to communicate over IR, you will see an icon
on the right at the bottom of the screen (Figure 1).
After this icon appears, a new "Virtual" serial port is registered in your PC. This serial port will have
a standard name, e.g.: COM3. When you configure Ozeki NG - SMS Gateway, you
should select this newly created COM port.
