If you are referring to 'bluetooth-wizard', it will not show me a device.  I'm 
told it will not show devices which are already paired.

I get what I assume is the same message from a:

[root@coyote test]#  ./simple-agent hci0 00:0C:84:00:86:F8
Creating device failed: org.bluez.Error.AlreadyExists: Bonding already exists

I just found /var/lib/bluetooth/11:11:11:11:11:11 which has a group of small 
files in it, 2 or 3 being subjected to an updated timestamp (data in these 
files is kept in GMT).

Is this the directory I need to mv someplace in order to rerun the bluetooth-
wizard?  Ok, did that, bluetooth-wizard did show me the device, but then the 
pin screen only showed for an almost subliminal time & then reported that it 
failed.

That generated a new /var/lib/bluetooth tree, so I nuked that, and ran 
"simple-agent hci0 <bdaddr of this dongle>"
That asked me for just one PIN and I gave it the default of 0000.  No errors.
And a new /var/lib/bluetooth tree was created.

An l2ping <bdaddr of remote>

Is this normal?

I just now went down to the coco and started a shell on both /t2 (wired) and 
/t3 (bluetooth)
minicom -s & set the serial port to /dev/ttyS0, exit and I am now a remote 
terminal on that machine.

If all this was working, I should get an essentially identical response using 
/dev/rfcomm0, right|wrong?

But a second minicom -s, check to see the serial port is /dev/rfcomm0, which 
does exist, select exit to minicom's main screen and it exits, reporting:
minicom: cannot open /dev/rfcomm0: No route to host

So that is where I am at.  Last Saturday morning it Just Worked(TM) without 
all this hassle.  I would like it to work again.  What is the next 
troubleshooting step here?, I'll go at your pace this time.

To those who suggested I use cu, or screen:  I don't have a cu, and 'screen' 
cannot open any device I've named.  From a lengthy read of the manpage, 
'screen' is a VT100 terminal, but without the ability to work with anything 
but the local system, so I don't see as it could be useful here.

I'll go see if I can find this cu.  Thanks everybody.
