[BRLTTY] Can this be done?

[Tom Masterson]

Ok  latest efforts.  I do not have any rfcomm* of any type in /dev either 
using find or ls.  I tried binding rfcomm0 to the device and it says it 
bound it just ine but when I try brltty -dserial:rfcomm0 I get a 
disconnect on the display and what is in the attached log.

I am seriously beginning to think my bluetoogh is not working correctly 
although it appears to be just fine.  I have never worked with a bluetooth 
dongle on linux and I have followed what procedures there are on the 
ubuntu site to install get it working and it finds the device or at least 
appears to find it.
