[BRLTTY] Brltty and Optelec BC640

[Dietmar Segbert]

Hello,
i have a quostion to the optelec alva bc640 brailledisplay.

How can i open the preferences-menu?

I can not open the preferences menu or help menu in version 4.4 under  
debian wheezy and in th android app version 4.5.

In linux from the smartpad-keys the middlekey will work as cursor-arrows- 
keys, bt the other keys have not effect.
Under android will open a windows and ask to configure the key, if i press  
one of the middle smartpad-keys.

Thanks for your help and for the very good android app.

Regards

Dietmar
