That is what I'm trying to use, and dbus looks to be denying it.

/dev/rfcomm0 is removed by the release, and created by the bind.

According to the docs I got from the a7 site, channel 1 is the default.

except:
[[email protected] bin]# minicom
minicom: cannot open /dev/rfcomm0: No such file or directory

but its there right now.
[[email protected] bin]# ls -l /dev/rfcomm*

I've downloaded all the bluez-3.30 stuff and if no more answers seem to be
