Forcing Windows 98/95 to Detect Your AT-232/485 Card

If Windows 98/95 does not detect your serial hardware, follow these steps to correct the problem:

  1. Select Start » Settings » Control Panel.
  2. Double-click on the System icon.
  3. Select the Device Manager page.
  4. Click the View devices by type button.
  5. If you are not using a shared IRQ board, double-click on the Ports (COM & LPT) icon to display a list of all ports that Windows 98/95 recognizes. If you are using a shared IRQ board, you must open the Multifunction adapter class, select the name of the interface, and click on the Remove button. If you have already installed the hardware, double click on Other Devices to display where Windows 98/95 lists the ports it does not recognize.
  6. Select a National Instruments port name from the list of ports that corresponds to a serial port (for example, COM 5, COM 6, COM 7, or COM 8).
  7. Click the Remove button, and click on OK to confirm the removal of the serial hardware information.
  8. Repeat steps 6 and 7 until all serial port entries are removed. Then click on Refresh to force Windows 98/95 to detect the serial hardware and display the New Hardware Found dialog box.
