If your device has no built-in modem and wants to connect to Internet, normally you will buy an external
modem and use cable to connect them together. But some mobile devices are so small that have no
RS-232 port for cable connection. Most of them have IrDA wireless built-in interface so that they can
connect with an IrDA modem without cable.
One usage of ACT IR-100S is to make those normal modem into IrDA compatible product by simply
connecting it to their serial port. And these devices with IR100S COM-IrDA bridge can communicate with
PC or your IrDA-cable devices wirelessly and don't need to modify neither hardware nor software
This simply test uses one PC with IrDA adapter with driver installed and an external modem connected
with IR100S. On PC uses 'Make New Connection' wizard of Dial-Up Networking to create a new dial-up
connection to your ISP through the IR modem. It should be able to find the modem, dial phone number,
establish a connection to internet and browse the web.
