>I get an RFCOMM connect error 111: Connection refused. I have

There are a number of possibilities for the connection refused error. To 
understand the error, I'll explain what it means in the more familiar IP 
environment. In that environment it means that the host is up and reachable, 
but that no service is listening on the requested port. For Bluetooth, it means 
something very similar - that the device is on, reachable, and paired, but that 
the device has no profile using the requested RFCOMM channel. The two most 
likely possibilities, therefore, are:

First: Perhaps you've specified the address of a device which is visible to 
your system, but which isn't your braille device. Please, therefore, 
double-check your braille device specification.

Second: Although unlikely, it could be that the HT driver is requesting an 
RFCOMM connection to the wrong channel. Please do an "sdptool browse
<address>" on your braille device and post the output to the list for us to 
analyze.

Neither should matter.

>The Braille Star works on bluetooth.

That's a good sign.
