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.

help
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 COSA/SRP driver has not been tested as non-modular yet.
config COSA
tristate "COSA/SRP sync serial boards support"
depends on ISA && m && ISA_DMA_API && HDLC && VIRT_TO_BUS
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.

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 clock source you will need lmcctl.

in /etc/modprobe.d/ for each interface, where X is 0, 1, 2, ..., or
simply use "alias hdlc* farsync" to indicate all of them.

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.
