D ESCRIPTION
This function is used to perform a special operation on a communications device. The number
to be placed in the
device argument to identify the device can be viewed in the status bar of
the Communications category when the device name is highlighted. The specific action to be
performed is indicated by the
function parameter, the values of which will depend upon the
type of device being addresses. The data parameter may be used to pass addition information
to the driver. Most drives do not support this function. Where supported, the operations are
driver-specific, and are documented separately.
