8	help
9	  Wide Area Networks (WANs), such as X.25, Frame Relay and leased
10	  lines, are used to interconnect Local Area Networks (LANs) over vast
11	  distances with data transfer rates significantly higher than those
12	  achievable with commonly used asynchronous modem connections.
13
14	  Usually, a quite expensive external device called a `WAN router' is
15	  needed to connect to a WAN. As an alternative, a relatively
16	  inexpensive WAN interface card can allow your Linux box to directly
17	  connect to a WAN.
18
19	  If you have one of those cards and wish to use it under Linux,
20	  say Y here and also to the WAN driver for your card.
21
22	  If unsure, say N.

46	  base-band modems, or any other device with the X.21, V.24, V.35 or
47	  V.36 interface) to your Linux box. The cards can work as the
48	  character device, synchronous PPP network device, or the Cisco HDLC
49	  network device.
50
51	  You will need user-space utilities COSA or SRP boards for downloading
52	  the firmware to the cards and to set them up. Look at the
