README file for the PCBIT-D Device Driver.
|
||
|
|
------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
The PCBIT is a Euro ISDN adapter manufactured in Portugal by Octal and
|
||
|
|
developed in cooperation with Portugal Telecom and Inesc.
|
||
|
|
The driver interfaces with the standard kernel isdn facilities
|
||
|
|
originally developed by Fritz Elfert in the isdn4linux project.
|
||
|
|
|
||
|
|
The common versions of the pcbit board require a firmware that is
|
||
|
|
distributed (and copyrighted) by the manufacturer. To load this
|
||
|
|
firmware you need "pcbitctl" available on the standard isdn4k-utils
|
||
|
|
package or in the pcbit package available in:
|
||
|
|
|
||
|
|
ftp://ftp.di.fc.ul.pt/pub/systems/Linux/isdn
|
||
|
|
|
||
|
|
Known Limitations:
|
||
|
|
|
||
|
|
- The board reset procedure is at the moment incorrect and will only
|
||
|
|
allow you to load the firmware after a hard reset.
|
||
|
|
|
||
|
|
- Only HDLC in B-channels is supported at the moment. There is no
|
||
|
|
current support for X.25 in B or D channels nor LAPD in B
|
||
|
|
channels. The main reason is that these two other protocol modes have,
|
||
|
|
to my knowledge, very little use. If you want to see them implemented
|
||
|
|
*do* send me a mail.
|
||
|
|
|
||
|
|
- The driver often triggers errors in the board that I and the
|
||
|
|
manufacturer believe to be caused by bugs in the firmware. The current
|
||
|
|
version includes several procedures for error recovery that should
|
||
|
|
allow normal operation. Plans for the future include cooperation with
|
||
|
|
the manufacturer in order to solve this problem.
