A new PCMCIA network card is not functioning correctly. To troubleshoot this, the socket information should be checked. How can this be done?

A.
cat/proc/pcmcia

B.
cardctl info

C.
cat/var/lib/pcmcia/stab

D.
cardctl -s

E.
cardmgr-s

Explanation:
Cardmgr monitors PCMCIA sockets for card insertion and removal events. When a card is inserted, cardmgr looks up the card in a database of known cards. If the card can be identified, appropriate device drivers will be loaded and bound to the card. When a card is ejected, that cards drivers will be shut down and unloaded if possible. Based on the contents of the PCMCIA card configuration database, cardmgr may also execute arbitrary commands when appropriate cards are either inserted or removed.
All insertion and removal events, device driver loads and unloads, and startup and shutdown commands are reported in the system log file. Warnings and errors will also be logged. Current card and device information for each socket is recorded in /var/lib/pcmcia/stab.
Cardctl is used to monitor and control the state of PCMCIA sockets. If a socket number is specified, the command will be applied to just one socket; otherwise, all sockets will be affected.
