Set SM Signal
The Set SM Signal command gives you control of firmware signals. The primary use of
this command is to set the status LED into identify mode. In identify mode the status
LED flashes on for a short period twice every 2 seconds. This allows an administrator to
locate the card in a system that has multiple cards.
