Chapter 4 PCMCIA Serial Hardware Installation, Verification, and Configuration

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.

Figure 4-6 shows an example of NI serial hardware that is installed

properly.
