First of all I would like to thank all of you to bring support for protocol converter into NVDA.

Here is one problem: Alva Satellite has 2 Satellite keypads, one on the leftside of display and one on the rightside with 6 keys on the each keypads, but NVDA treats them as one keypad. I do not know if it is bug of NVDA or bug of protocol converter, so I have opened this ticket as @LeonarddeR suggested in private conversation.

Steps to reproduce:

1. connect Alva Satellite to computer via protocol converter
2. wait system to install it on the system if it was not installed already
3. from the braille settings choose Optelec bc6...
4. turn input help on
5. play with keys on Satellite display

Expected behavior:

NVDA should differentiate between Satellite keypads, so NVDA could emulates most of keys which are on bc6 displays.

Actual behavior:

Now NVDA emulates: sp1, sp4, and sp left, right, up and down on both satellite keypads. So there are not: sp2, sp3, spEnter, etouch1, etouch3 and etouch4.
