config WAN
	bool "Wan interfaces support"
	---help---
	  Wide Area Networks (WANs), such as X.25, Frame Relay and leased
	  lines, are used to interconnect Local Area Networks (LANs) over vast
	  distances with data transfer rates significantly higher than those
	  achievable with commonly used asynchronous modem connections.

	  Usually, a quite expensive external device called a `WAN router' is
	  needed to connect to a WAN. As an alternative, a relatively
	  inexpensive WAN interface card can allow your Linux box to directly
	  connect to a WAN.

	  If you have one of those cards and wish to use it under Linux,
	  say Y here and also to the WAN driver for your card.

	  If unsure, say N.

	  Driver for Comtrol Hostess SV-11 network card which
	  operates on low speed synchronous serial links at up to
	  256Kbps, supporting PPP and Cisco HDLC.

	  The driver will be compiled as a module: the

# The COSA/SRP driver has not been tested as non-modular yet.
config COSA
	tristate "COSA/SRP sync serial boards support"
	depends on WAN && ISA && m && ISA_DMA_API
	---help---
	  Driver for COSA and SRP synchronous serial boards.

	  These boards allow to connect synchronous serial devices (for example
	  base-band modems, or any other device with the X.21, V.24, V.35 or
	  V.36 interface) to your Linux box. The cards can work as the
	  character device, synchronous PPP network device, or the Cisco HDLC
	  network device.

	  You will need user-space utilities COSA or SRP boards for downloading
 	  the firmware to the cards and to set them up. Look at the
	  <http://www.fi.muni.cz/~kas/cosa/> for more information. You can also
	  read the comment at the top of the <file:drivers/net/wan/cosa.c> for
	  details about the cards and the driver itself.

	  The driver will be compiled as a module: the
	  module will be called cosa.

	  driver.

	  To compile this driver as a module, choose M here: the
	  module will be called dscc4.

config DSCC4_PCISYNC
	bool "Etinc PCISYNC features"
	depends on DSCC4
	help
	  Due to Etinc's design choice for its PCISYNC cards, some operations
	  are only allowed on specific ports of the DSCC4. This option is the
	  only way for the driver to know that it shouldn't return a success
	  code for these operations.

	  Please say Y if your card is an Etinc's PCISYNC.

config DSCC4_PCI_RST
	bool "Hard reset support"
	depends on DSCC4
	help
	  Various DSCC4 bugs forbid any reliable software reset of the ASIC.
	  As a replacement, some vendors provide a way to assert the PCI #RST
	  pin of DSCC4 through the GPIO port of the card. If you choose Y,
	  the driver will make use of this feature before module removal
	  (i.e. rmmod). The feature is known to be available on Commtech's
	  cards. Contact your manufacturer for details.

	  Say Y if your card supports this feature.

	  - LMC 1200 with on board DSU board allows you to connect your Linux
	  box directly to a T1 or E1 circuit.

	  - LMC 5200 board provides a HSSI interface capable of running up to
	  52 Mbits per second.

	  - LMC 5245 board connects directly to a T3 circuit saving the
	  additional external hardware.

	  To change setting such as syncPPP vs Cisco HDLC or clock source you
	  will need lmcctl.  It is available at <ftp://ftp.lanmedia.com/>
