Build 86

Build 85

- dep runway selection on DEP/ARR wasn't working, fixed
- battery handling for Engravity added
- RCDU Extension: Setting bit 6 of the high byte, using the same rules as above, you can send keyboard commands to the RCDU. E.g. Sending “A” to the CDU is value 65, to the RCDU it is (256 * 2^6) + 65 = 256 * 64 + 65 = 16449 (this command will then of course be ignored by the CDU) Updated 14-12-2006

Basics
======

The Remote CDU (RCDU) is not part of a fully redundant system, it connects to the main CDU,
any Project Magenta CDU (Build 294 or later). The pages are generated there and 
transferred via the NetDir. 

To set up the NetDir, you can do it either in the old way (edit RCDU.INI manually and
enter it there) or, on the main CDU, go to INIT/REF, MAINT, NETDIR (LSK 5R) and 
have it created automatically)

Connecting to the main CDU
==========================

The connection to the main CDU is established automatically. It is not important whether
the RCDU is running on a networked computer or on the same computer as the main CDU, it is
also irrelevant which one is started first. Once FS and both CDUs (main and remote) are running,
and the NetDir is set up correctly, they will connect automatically.

When one CDU stops running, it will inform the other one right away. In the case of the 
Remote CDU, the screen will turn blank. 

The operation of the Remote CDU is identical to using the single FMC system.
