Auto-dialer

Since the increased needs of dial-up internet access via 2G/3G for PAC products, ICPDAS develops a program to manage dial-up connection. This application allows users to connect to internet by auto dial-up connection on PAC, and it will automatically connect to network while it logout. It can assure you of the network connection status.

Besides, ICPDAS provides an API to auto dial-up connection; users can integrate the function with their own development program, and don’t need to execute it additional.
