- Has IMHO nithing to do woth internal devices...
- Adds power to the line for the termination resistors.

- A bit confusing... and WRONG...
- The manual is VERY CLEAR about this jumper:
- Leave OPEN if no internal devices installed (permanently ON).
- Set 1-2 if any internal AND any external, OR any internal and NO external
- devices installed (AUTO enable).
- Of course, in any case, the last device has to be terminated.

- No comment on this...
- In fact, I don`t trust those settings... if you`ve got any problems,
- setting all devices to "normal" asynchronous mode is IMHO the best slution
- to avoid unneccessary probs. turning of Reselection could help, too, as
- some devices seem to have problems with it turned on.
