Not quite.

auto is just for detecting the driver. If you specify auto for the driver then 
brltty will try the various protocols it knows till it finds the one that 
works.

Brltty has no concept of just trying serial or Bluetooth. For serial, this is 
because we feel that arbitrarily probing all of the known ports is a 
fundamentally dangerous thing to be doing. For Bluetooth, it's because we can't 
possibly know what the address is. So, for both serial and Bluetooth you need 
to at least speicfy which specific device to use. So, for example, you could 
specify something like this in brltty.conf (or via -d):

   braille-device usb:,serial:ttyS0,bluetooth:01:23:45:67:89:AB

>Sorry for my ignorance, 

It's "against the law" (at least on this list) to feel that way. I myself may 
finally begin to suspect that you may be ignorant if you ask the very same 
question a hundred times and still don't get it even after the answer has been 
given in a hundred different ways. :-) No one is ever ignorant simply because 
he doesn't yet know some piece of information.

I hope you have a rich uncle who's named you in his will! Sadly, these devices 
aren't very cheap. A good thing is that, if you're actually blind, some 
employers and government programs do help to pay for them. This, of course, is 
very country-dependent.
