Chapter 2 Installation and Verification
PCMCIA Serial for Windows Me/9x 2-4 ni.com
Verify the Installation
When you begin to verify the installation, keep in mind that the serial ports
built into the computer are typically named from COM1 to COM4.
Windows Me/9x typically issues port names to the ports on NI serial
hardware starting with COM5, COM6, and so on. If not enough resources
are available to assign to all the NI serial ports, the port with the higher
COMx name is left unconfigured.
Double-click on the System icon in the Control Panel. In the System
Properties window that appears, select the Device Manager tab, and click
on the View devices by type button at the top of the page. If necessary,
double-click on the Ports (COM & LPT) icon to view all of the ports.
The two-port and four-port PCMCIA cards are configured as devices
belonging to the “multi-function adapters” class. The multi-function parent
device is listed under the Multi-function adapters icon, and each child
device is listed as a port under the Ports (COM & LPT) icon. If you have
installed one of these interfaces, double-click on the Multi-function
adapters icon as well as the Ports (COM & LPT) icon.
If a circled exclamation point appears through the port icon, the serial port
is not installed properly. A problem with the port could have occurred
because Windows Me/9x could not acquire resources for the port, or
because an interrupt request resource conflict exists. If no circled
exclamation point appears, the serial hardware is installed correctly.
Figure2 -4 shows an example of NI serial hardware that is installed
properly and Figure 2-5 shows an example of NI serial hardware that is not
working properly.
