I have added two buttons to the CDS OVERVIEW MEDM screen:

Press All Diag Reset Buttons

The name says it all. It opens an xterm window, and then sequences through all running models pressing the DIAG_RESET button on the GDS_TP screen

EDCU disconnected channels

This is a small yellow button, labeled with an exclamation mark,  next the the EDCU status LED. When the LED is purple, pressing the button will open an xterm and list the EDCU channels which are disconnected. The xterm is held open so you can read it at your leisure, please close it when you are done with it.
