[BRLTTY] Brlapi under Android again

[Peter Lecky]

Hello All,

Actually finishing intgration of brlapi in our application and thinking 
how to fix this:

I successfully connect to brltty and start to monitor 
PARAM_DEVICE_ONLINE and some other parameters.

If there is a display communicating with brltty when i connect, i 
successfully receive true status of online parameter, can call 
connection.enterTtyMode(0); and start to work with the display.

But there is a problem if there is no display when i connect to service. 
I receive change notification of online parameter immediately when some 
display successfuly connects to brltty which is ok, (i actually play 
with orbit 20 via bluetooth). But my app crashes when i try to call 
connection.enterTtyMode(0); in this case.

I tried to check connection.isUnusable() (may be that connection must be 
reset after display reconnection) but it returns false, so no reason to 
reconnect.

What should be wrong?

I thought to reset connection if I receive online parameter change 
notification later than say 1 second after successfull connection, but 
it looks like a nasty solution. :) Is there something better i can do?

  Thanks for ideas
