|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.
|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.
|There tree cards installed in your machine at IO-base addresses 0xd000, 0xd400
|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.
