Alternately, the driver can be compiled to support
Only one line for each card is needed in the kernel configuration file.
The first card's ports will be installed from ar0.
The numbering of the
next card will continue where the first stopped, e.g. if the first card
is a two port card it will use ar0 and ar1.
The next card will then
start at ar2.
The card only supports IRQ 3, 5, 7, 10, 11, 12 and 15.
The iomem area is a 16Kb block and must start at a 16Kb boundary.
If the kernel is compiled with

Connecting to this hook enables the transmission of raw HDLC frames.
The node will have the same name as the device with ``sync_''
