Chapter 4 PCMCIA Serial Hardware Installation, Verification, and Configuration
© National Instruments Corporation 4-11 Serial Hardware and Software for Windows
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.
