2Fax with isdn4linux
3===================
4
5When enabled during kernel configuration, the tty emulator
6of the ISDN subsystem is capable of the Fax Class 2 commands.
7
8This only makes sense under the following conditions :
9
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)
14
15
16NOTE: 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.
