Landline Modems
Communications programs such as HyperTerminal, Procomm Plus, or Speaker Phone
dont seem to work or they lock Windows
If you are using the internal modem, be sure to specify COM3 as the communications port.
Verify with your company that your computer has an internal modem installed.
When you first try to use HyperTerminal or similar application, the system responds with a message asking if
you want to install the modem. Answer Yes to this question and follow the instructions on the screen to
install it.
Make sure the IRQ lines for COM3 and COM4 are specified for Windows. See Section 6 Customizing Your
Bios Settings to view and change IRQ settings.
Third-party applications dont work with COM3
Make sure a modem is installed. Locate the Config string label on the bottom of the GoBook computer; a
modem is not installed if the seventh digit is Z.
Make sure your application is set to use COM3.
Make sure your application is using the correct communication settings (baud, parity, etc.).
The modem may not be powered on. If you are using a DOS application, before running the application, make
sure that MODEM ON is called from the DOS command line or from a batch file.
Make sure that the Interrupt Request lines (IRQs) for COM3 or COM4 specified for Windows match the IRQ
lines specified in the SCU.
You may also need to try a different IRQ setting. See Section 6 Customizing Your Bios Settings.
