-The driver for the HFC-PCI and HFC-PCI-A chips from CCD may be used
-for many OEM cards using this chips.
-Additionally the driver has a special feature which makes it possible
-to read the echo-channel of the isdn bus. So all frames in both directions
-may be logged.
-When the echo logging feature is used the number of available B-channels
-for a HFC-PCI card is reduced to 1. Of course this is only relevant to
-the card, not to the isdn line.
-To activate the echo mode the following ioctls must be entered:
-
-hisaxctrl <driver/cardname> 10 1
-
-This reduces the available channels to 1. There must not be open connections
-through this card when entering the command.
-And then:
-
-hisaxctrl <driver/cardname> 12 1
-
-This enables the echo mode. If Hex logging is activated the isdnctrlx
-devices show a output with a line beginning of HEX: for the providers
-exchange and ECHO: for isdn devices sending to the provider.
-
-If more than one HFC-PCI cards are installed, a specific card may be selected
-at the hisax module load command line. Supply the load command with the desired
-IO-address of the desired card.
-Example:
-There tree cards installed in your machine at IO-base addresses 0xd000, 0xd400
-and 0xdc00
-If you want to use the card at 0xd400 standalone you should supply the insmod
-or depmod with type=35 io=0xd400.
-If you want to use all three cards, but the order needs to be at 0xdc00,0xd400,
-0xd000 you may give the parameters type=35,35,35 io=0xdc00,0xd400,0xd00
-Then the desired card will be the initialised in the desired order.
-If the io parameter is used the io addresses of all used cards should be
-supplied else the parameter is assumed 0 and a auto search for a free card is
-invoked which may not give the wanted result.
