Port Configuration

AT Command Tester uses Java-based serial drivers to interface to the modem. The ‘Find Ports’ button will automatically find all ports available in the system. The user can connect the appropriate modem port with the desired port speed.

Command mode

After connecting successfully to the modem, users can send single AT commands under ‘Command Mode’ tab. The drop down provides a list of AT commands with description and examples. The users can modify or enter their own AT command in the text box.

Users can develop their own scripts for specific set of tasks such as call setup , send SMS, HTTP access etc. Users can also include descriptive comments in their script.

Data Call

The ‘Data Call’ tab provides the interfaces to setup data call with the GSM network. ‘Get PDP Contexts’ button will list all the PDP context profiles stored on the SIM. Users can also add or update new PDP context profile. Users can then connect to the selected profile. AT Command Tester will first check whether the device is registered on the network. If so, it will attach and connect to the network with the selected PDP context credentials.

More feature additions such as voice call, SMS, Phone book functions, HTTP, FTP, TCP/IP are planned for AT Command Tester tool. Suggestions from this blog readers are also welcome.

      Java will not accept this program as a security risk, it is blocked by Java
