If Windows does not detect your serial hardware correctly, or you have
been using your serial hardware with the default Windows Me/9x serial
driver or an older version of the NI-Serial software, Windows Me/9x does
not display the New Hardware Found dialog box. To fix this problem,
follow these steps:
1. Select Start»Settings»Control Panel.
2. Double-click on the System icon.
3. Select the Device Manager tab.
4. ClickontheView devices by type button.
5. Double-click on the Ports (COM & LPT) icon to display a list of all
ports that Windows Me/9x recognizes.
If you have already installed the hardware, double-click on Other
Devices to display where Windows Me/9x 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). Figure D-3 shows the Ports list in the Device Manager with
a port selected. (This example shows an AT interface.)
Note
To remove ports on shared IRQ cards, you must open the Multifunction adapter
class, select the name of the interface, and click on the Remove button.
