can you show what the output of sdpcontrol is when examining this service?
(try search for protocol 0x0003 should give all RFCOMM channels)
IIRC if you are connecting to a serial port service then it is not always
the case that there will be an AT command interpreter at the other end..
also, the patch below adds support to print out the primary language
ServiceName to the port of sdpcontrol I made for NetBSD. It might not
apply cleanly to original sdpcontrol but should not be too difficult to
adapt and it seems quite useful..
I haven't committed it here because its not really complete as the string
that is produced is not guaranteed to be ASCII (the spec recommends using
UTF-8) but I would have to examine the languagebase settings and do some
iconv magic to get it 100% correct.
