41	1. About the driver
43	   The drivers/isdn/hysdn subdir contains a driver for HYPERCOPEs active 
44	   PCI isdn cards Champ, Ergo and Metro. To enable support for this cards
45	   enable ISDN support in the kernel config and support for HYSDN cards in
46	   the active cards submenu. The driver may only be compiled and used if 
47	   support for loadable modules and the process filesystem have been enabled.
49	   These cards provide two different interfaces to the kernel. Without the
50	   optional CAPI 2.0 support, they register as ethernet card. IP-routing
51	   to a ISDN-destination is performed on the card itself. All necessary
52	   handlers for various protocols like ppp and others as well as config info
53	   and firmware may be fetched from Hypercopes WWW-Site www.hypercope.de.
55	   With CAPI 2.0 support enabled, the card can also be used as a CAPI 2.0 
56	   compliant devices with either CAPI 2.0 applications 
57	   (check isdn4k-utils) or -using the capidrv module- as a regular
58	   isdn4linux device. This is done via the same mechanism as with the 
59	   active AVM cards and in fact uses the same module.
62	2. Loading/Unloading the driver
64	   The module has no command line parameters and auto detects up to 10 cards
65	   in the id-range 0-9.
66	   If a loaded driver shall be unloaded all open files in the /proc/net/hysdn
67	   subdir need to be closed and all ethernet interfaces allocated by this 
68	   driver must be shut down. Otherwise the module counter will avoid a module
69	   unload.
71	   If you are using the CAPI 2.0-interface, make sure to load/modprobe the
72	   kernelcapi-module first.
74	   If you plan to use the capidrv-link to isdn4linux, make sure to load
75	   capidrv.o after all modules using this driver (i.e. after hysdn and
76	   any avm-specific modules).
78	3. Entries in the /proc filesystem
80	   When the module has been loaded it adds the directory hysdn in the 
81	   /proc/net tree. This directory contains exactly 2 file entries for each 
82	   card. One is called cardconfX and the other cardlogX, where X is the
83	   card id number from 0 to 9. 
84	   The cards are numbered in the order found in the PCI config data.
86	4. The /proc/net/hysdn/cardconfX file
88	   This file may be read to get by everyone to get info about the cards type, 
89	   actual state, available features and used resources.
90	   The first 3 entries (id, bus and slot) are PCI info fields, the following
91	   type field gives the information about the cards type:
93	   4 -> Ergo card (server card with 2 b-chans)
94	   5 -> Metro card (server card with 4 or 8 b-chans)
95	   6 -> Champ card (client card with 2 b-chans)   
97	   The following 3 fields show the hardware assignments for irq, iobase and the
98	   dual ported memory (dp-mem).
99	   The fields b-chans and fax-chans announce the available card resources of
100	   this types for the user.
101	   The state variable indicates the actual drivers state for this card with the
102	   following assignments.
104	   0 -> card has not been booted since driver load
105	   1 -> card booting is actually in progess
106	   2 -> card is in an error state due to a previous boot failure
107	   3 -> card is booted and active
109	   And the last field (device) shows the name of the ethernet device assigned
110	   to this card. Up to the first successful boot this field only shows a -
111	   to tell that no net device has been allocated up to now. Once a net device
112	   has been allocated it remains assigned to this card, even if a card is
113	   rebooted and an boot error occurs. 
115	   Writing to the cardconfX file boots the card or transfers config lines to 
116	   the cards firmware. The type of data is automatically detected when the 
117	   first data is written. Only root has write access to this file.
118	   The firmware boot files are normally called hyclient.pof for client cards
119	   and hyserver.pof for server cards.
120	   After successfully writing the boot file, complete config files or single
121	   config lines may be copied to this file.
122	   If an error occurs the return value given to the writing process has the 
123	   following additional codes (decimal):
125	   1000 Another process is currently bootng the card
126	   1001 Invalid firmware header
127	   1002 Boards dual-port RAM test failed
128	   1003 Internal firmware handler error
129	   1004 Boot image size invalid
130	   1005 First boot stage (bootstrap loader) failed
131	   1006 Second boot stage failure
132	   1007 Timeout waiting for card ready during boot
133	   1008 Operation only allowed in booted state
134	   1009 Config line too long 
135	   1010 Invalid channel number 
136	   1011 Timeout sending config data
138	   Additional info about error reasons may be fetched from the log output. 
140	5. The /proc/net/hysdn/cardlogX file
142	   The cardlogX file entry may be opened multiple for reading by everyone to 
143	   get the cards and drivers log data. Card messages always start with the
144	   keyword LOG. All other lines are output from the driver. 
145	   The driver log data may be redirected to the syslog by selecting the 
146	   appropriate bitmask. The cards log messages will always be send to this
147	   interface but never to the syslog.
149	   A root user may write a decimal or hex (with 0x) value t this file to select
150	   desired output options. As mentioned above the cards log dat is always 
151	   written to the cardlog file independent of the following options only used
152	   to check and debug the driver itself:
154	   For example: 
155	   echo "0x34560078" > /proc/net/hysdn/cardlog0
156	   to output the hex log mask 34560078 for card 0.
158	   The written value is regarded as an unsigned 32-Bit value, bit ored for 
159	   desired output. The following bits are already assigned:
161	   0x80000000   All driver log data is alternatively via syslog 
162	   0x00000001   Log memory allocation errors
163	   0x00000010   Firmware load start and close are logged
164	   0x00000020   Log firmware record parser
165	   0x00000040   Log every firmware write actions
166	   0x00000080   Log all card related boot messages
167	   0x00000100   Output all config data sent for debugging purposes
168	   0x00000200   Only non comment config lines are shown wth channel
169	   0x00000400   Additional conf log output
170	   0x00001000   Log the asynchronous scheduler actions (config and log)
171	   0x00100000   Log all open and close actions to /proc/net/hysdn/card files
172	   0x00200000   Log all actions from /proc file entries
173	   0x00010000   Log network interface init and deinit
175	6. Where to get additional info and help
177	   If you have any problems concerning the driver or configuration contact
