read the peak wave out values for both channels by using standard Windows Mixer
API calls.
The Optimod-PC driver creates two mixer destinations, one for output and one for
input. The following tables list the relevant enumerated Windows Mixer compo-
nents by name for each destination, along with their corresponding control in the
Optimod-PC Application.

Each mixer component supports a mono volume control and a mono mute control.
Windows mixer controls can support more than one channel. However, in this case,
these controls only allow one channel to be set. The same setting is applied equally
to both the left and right channels.
For audio source selection and muting, the Input Destination controls are commonly
used. In effect, the Output Destination controls will control all of the inputs at once.
Therefore, if individual input source switching, muting, or level setting is required,
use the Input Destination controls.

Administering the 1101 through Serial Ports

Using a terminal program like HyperTerminal, or an ASCII programmable GPIO de-
vice, you can control an 1101 card through a serial port of the computer that hosts
the 1101 you wish to access. When you are connected, you can retrieve information
