5 When enabled during kernel configuration, the tty emulator
6 of the ISDN subsystem is capable of the Fax Class 2 commands.
8 This only makes sense under the following conditions :
10 - You need the commands as dummy, because you are using
11 hylafax (with patch) for AVM capi.
12 - You want to use the fax capabilities of your isdn-card.
13 (supported cards are listed below)
16 NOTE: This implementation does *not* support fax with passive
17 ISDN-cards (known as softfax). The low-level driver of
18 the ISDN-card and/or the card itself must support this.
24 Eicon DIVA Server BRI/PCI
25 - full support with both B-channels.
27 Eicon DIVA Server 4BRI/PCI
28 - full support with all B-channels.
30 Eicon DIVA Server PRI/PCI
31 - full support on amount of B-channels
32 depending on DSPs on board.
36 The command set is known as Class 2 (not Class 2.0) and
37 can be activated by AT+FCLASS=2
40 The interface between the link-level-module and the hardware-level driver
41 is described in the files INTERFACE.fax and INTERFACE.
