2 | README file for the PCBIT-D Device Driver. |
3 | ------------------------------------------------------------------------------ |
4 | |
5 | The PCBIT is a Euro ISDN adapter manufactured in Portugal by Octal and |
6 | developed in cooperation with Portugal Telecom and Inesc. |
7 | The driver interfaces with the standard kernel isdn facilities |
8 | originally developed by Fritz Elfert in the isdn4linux project. |
9 | |
10 | The common versions of the pcbit board require a firmware that is |
11 | distributed (and copyrighted) by the manufacturer. To load this |
12 | firmware you need "pcbitctl" available on the standard isdn4k-utils |
13 | package or in the pcbit package available in: |
14 | |
15 | ftp://ftp.di.fc.ul.pt/pub/systems/Linux/isdn |
16 | |
17 | Known Limitations: |
18 | |
19 | - The board reset procedure is at the moment incorrect and will only |
20 | allow you to load the firmware after a hard reset. |
21 | |
22 | - Only HDLC in B-channels is supported at the moment. There is no |
23 | current support for X.25 in B or D channels nor LAPD in B |
24 | channels. The main reason is that these two other protocol modes have, |
25 | to my knowledge, very little use. If you want to see them implemented |
26 | *do* send me a mail. |
27 | |
28 | - The driver often triggers errors in the board that I and the |
29 | manufacturer believe to be caused by bugs in the firmware. The current |
30 | version includes several procedures for error recovery that should |
31 | allow normal operation. Plans for the future include cooperation with |
32 | the manufacturer in order to solve this problem. |
33 | |
34 | Information/hints/help can be obtained in the linux isdn |
35 | mailing list (isdn4linux@listserv.isdn4linux.de) or directly from me. |
