-	  This driver allows you to use an ISDN adapter for networking

-	  channel-bundling, callback and caller-authentication without having
-	  a daemon running.  A reduced T.70 protocol is supported with tty's
-	  suitable for German BTX.  On D-Channel, the protocols EDSS1
-	  (Euro-ISDN) and 1TR6 (German style) are supported.  See
-	  <file:Documentation/isdn/README> for more information.
-
-	  ISDN support in the linux kernel is moving towards a new API,
-	  called CAPI (Common ISDN Application Programming Interface).
-	  Therefore the old ISDN4Linux layer will eventually become obsolete.
-	  It is still available, though, for use with adapters that are not
-	  supported by the new CAPI subsystem yet.

- *
- * gerdes_amd7930.c     Amd 79C30A and 79C32A specific routines
- *                      (based on HiSax driver by Karsten Keil)
- *

- *
- * Notes:
- * Version 0.99 is the first release of this driver and there are
- * certainly a few bugs.
- *
- * Please don't report any malfunction to me without sending
- * (compressed) debug-logs.
- * It would be nearly impossible to retrace it.
- *
- * Log D-channel-processing as follows:
- *
- * 1. Load hisax with card-specific parameters, this example ist for
- *    Formula-n enter:now ISDN PCI and compatible
- *    (f.e. Gerdes Power ISDN PCI)
- *
- *    modprobe hisax type=41 protocol=2 id=gerdes
- *
- *    if you chose an other value for id, you need to modify the
- *    code below, too.
- *
- * 2. set debug-level
- *
- *    hisaxctrl gerdes 1 0x3ff
- *    hisaxctrl gerdes 11 0x4f
- *    cat /dev/isdnctrl >> ~/log &
- *
- * Please take also a look into /var/log/messages if there is
- * anything importand concerning HISAX.
- *
- *
- * Credits:
- * Programming the driver for Formula-n enter:now ISDN PCI and
- * necessary this driver for the used Amd 7930 D-channel-controller
- * was spnsored by Formula-n Europe AG.
- * Thanks to Karsten Keil and Petr Novak, who gave me support in
- * Hisax-specific questions.
- * I want so say special thanks to Carl-Friedrich Braun, who had to
- * answer a lot of questions about generally ISDN and about handling
- * of the Amd-Chip.

- * Notes:
- * This driver interfaces to netjet.c which performs B-channel
- * processing.
- *
- * Version 0.99 is the first release of this driver and there are
- * certainly a few bugs.
- * It isn't testet on linux 2.4 yet, so consider this code to be
- * beta.
- *
- * Please don't report me any malfunction without sending
- * (compressed) debug-logs.
- * It would be nearly impossible to retrace it.
- *
- * Log D-channel-processing as follows:
- *
- * 1. Load hisax with card-specific parameters, this example ist for
- *    Formula-n enter:now ISDN PCI and compatible
- *    (f.e. Gerdes Power ISDN PCI)
- *
- *    modprobe hisax type=41 protocol=2 id=gerdes
- *
- *    if you chose an other value for id, you need to modify the
- *    code below, too.
- *
- * 2. set debug-level
- *
- *    hisaxctrl gerdes 1 0x3ff
- *    hisaxctrl gerdes 11 0x4f
- *    cat /dev/isdnctrl >> ~/log &
- *
- * Please take also a look into /var/log/messages if there is
- * anything importand concerning HISAX.
- *
- *
- * Credits:
- * Programming the driver for Formula-n enter:now ISDN PCI and
- * necessary the driver for the used Amd 7930 D-channel-controller
- * was spnsored by Formula-n Europe AG.
- * Thanks to Karsten Keil and Petr Novak, who gave me support in
- * Hisax-specific questions.
- * I want so say special thanks to Carl-Friedrich Braun, who had to
- * answer a lot of questions about generally ISDN and about handling
- * of the Amd-Chip.

-config ISDN_PPP
-	bool "Support synchronous PPP"
-	depends on INET
-	select SLHC
-	help
-	  Over digital connections such as ISDN, there is no need to
-	  synchronize sender and recipient's clocks with start and stop bits
-	  as is done over analog telephone lines. Instead, one can use
-	  "synchronous PPP". Saying Y here will include this protocol. This
-	  protocol is used by Cisco and Sun for example. So you want to say Y
-	  here if the other end of your ISDN connection supports it. You will
-	  need a special version of pppd (called ipppd) for using this
-	  feature. See <file:Documentation/isdn/README.syncppp> and
-	  <file:Documentation/isdn/syncPPP.FAQ> for more information.
-
-config ISDN_PPP_VJ
-	bool "Use VJ-compression with synchronous PPP"
-	depends on ISDN_PPP
-	help
-	  This enables Van Jacobson header compression for synchronous PPP.
-	  Say Y if the other end of the connection supports it.
-
-config ISDN_MPP
-	bool "Support generic MP (RFC 1717)"
-	depends on ISDN_PPP
-	help
-	  With synchronous PPP enabled, it is possible to increase throughput
-	  by bundling several ISDN-connections, using this protocol. See
-	  <file:Documentation/isdn/README.syncppp> for more information.
-
-config IPPP_FILTER
-	bool "Filtering for synchronous PPP"
-	depends on ISDN_PPP
-	help
-	  Say Y here if you want to be able to filter the packets passing over
-	  IPPP interfaces.  This allows you to control which packets count as
-	  activity (i.e. which packets will reset the idle timer or bring up
-	  a demand-dialled link) and which packets are to be dropped entirely.
-	  You need to say Y here if you wish to use the pass-filter and
-	  active-filter options to ipppd.
-
-config ISDN_PPP_BSDCOMP
-	tristate "Support BSD compression"
-	depends on ISDN_PPP
-	help
-	  Support for the BSD-Compress compression method for PPP, which uses
-	  the LZW compression method to compress each PPP packet before it is
-	  sent over the wire. The machine at the other end of the PPP link
-	  (usually your ISP) has to support the BSD-Compress compression
-	  method as well for this to be useful. Even if they don't support it,
-	  it is safe to say Y here.
-
-config ISDN_AUDIO
-	bool "Support audio via ISDN"
-	help
-	  If you say Y here, the modem-emulator will support a subset of the
-	  EIA Class 8 Voice commands. Using a getty with voice-support
-	  (mgetty+sendfax by <gert@greenie.muc.de> with an extension, available
-	  with the ISDN utility package for example), you will be able to use
-	  your Linux box as an ISDN-answering machine. Of course, this must be
-	  supported by the lowlevel driver also. Currently, the HiSax driver
-	  is the only voice-supporting driver. See
-	  <file:Documentation/isdn/README.audio> for more information.
-
-config ISDN_TTY_FAX
-	bool "Support AT-Fax Class 1 and 2 commands"
-	depends on ISDN_AUDIO
-	help
-	  If you say Y here, the modem-emulator will support a subset of the
-	  Fax Class 1 and 2 commands. Using a getty with fax-support
-	  (mgetty+sendfax, hylafax), you will be able to use your Linux box as
-	  an ISDN-fax-machine. This must be supported by the lowlevel driver
-	  also. See <file:Documentation/isdn/README.fax> for more information.
-
-config ISDN_X25
-	bool "X.25 PLP on top of ISDN"
-	depends on X25
-	help
-	  This feature provides the X.25 protocol over ISDN connections.
-	  See <file:Documentation/isdn/README.x25> for more information
-	  if you are thinking about using this.
-

-
-config ISDN_DRV_LOOP
-	tristate "isdnloop support"
-	depends on BROKEN_ON_SMP
-	help
-	  This driver provides a virtual ISDN card. Its primary purpose is
-	  testing of linklevel features or configuration without getting
-	  charged by your service-provider for lots of phone calls.
-	  You need will need the loopctrl utility from the latest isdn4k-utils
-	  package to set up this driver.
-
-config ISDN_DIVERSION
-	tristate "Support isdn diversion services"
-	help
-	  This option allows you to use some supplementary diversion
-	  services in conjunction with the HiSax driver on an EURO/DSS1
-	  line.
-
-	  Supported options are CD (call deflection), CFU (Call forward
-	  unconditional), CFB (Call forward when busy) and CFNR (call forward
-	  not reachable). Additionally the actual CFU, CFB and CFNR state may
-	  be interrogated.
-
-	  The use of CFU, CFB, CFNR and interrogation may be limited to some
-	  countries. The keypad protocol is still not implemented. CD should
-	  work in all countries if the service has been subscribed to.
-
-	  Please read the file <file:Documentation/isdn/README.diversion>.

-   to the (de)compressor, but indeed is not covered by the current API to
-   the (de)compressor. The API is a prototype version from PPP where only
-   some (de)compressors have yet been implemented and all of them are
-   rather simple in their reset handling. Especially, their is only one
-   outstanding ResetAck at a time with all of them and ResetReq/-Acks do
-   not have parameters. For this very special case it was sufficient to
-   just return an error code from the decompressor and have a single
-   reset() entry to communicate all the necessary information between
-   the framework and the (de)compressor. Bad enough, LZS is different
-   (and any other compressor may be different, too). It has multiple
-   histories (eventually) and needs to Reset each of them independently
-   and thus uses multiple outstanding Acks and history numbers as an
-   additional parameter to Reqs/Acks.
-   All that makes it harder to port the reset state engine into the
-   kernel because it is not just the same simple one as in (i)pppd but
-   it must be able to pass additional parameters and have multiple out-
-   standing Acks. We are trying to achieve the impossible by handling
-   reset transactions independent by their id. The id MUST change when
-   the data portion changes, thus any (de)compressor who uses more than
-   one resettable state must provide and recognize individual ids for
-   each individual reset transaction. The framework itself does _only_
-   differentiate them by id, because it has no other semantics like the
-   (de)compressor might.
-   This looks like a major redesign of the interface would be nice,
-   but I don't have an idea how to do it better. */
