Landline Modems
Communications programs such as HyperTerminal, Procomm Plus, or Speaker Phone
don’t 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 don’t 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.
