This driver is for PCI200SYN cards made by Goramo sp. j.
If you have such a card, say Y here and see
<http://hq.pm.waw.pl/pub/hdlc/>
If you want to compile the driver as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called pci200syn.
If unsure, say N here.
