I fired up a terminal proggy on that device, but none of the answers I got
were english, like its not running at 9600 baud on the serial interface. I
get answers, but they are something like |C> where I recall seeing an <ACK> or
<NAK> out of it before.

I took some time and replaced the power connector coming out of the coco which
was getting flaky after 15 years, and now I have much cleaner video. It had
one of those 4 pin automotive connectors where the male & female are swapped
so that when mated, its polarized. But I think they make those things with
some sort of a pressure connection that goes away in 15 years just laying
there. So since I'm not getting english answers I think I'll toss that
problem back at Roger & see what he says.

I suppose I could diddle the baud rate of the terminal proggy too, maybe it
didn't default to 9600 when I do a power up with the reset button held down,
which is supposed to reset it to factory defaults.

Yeah, next test, brb.

I went thru the baud rate settings, testing each increment until I got back
around to 9600, at which point the eb101 started giving me english answers.
The answers all looked sensible, including an 'lst visible' which returned the
address on these dinky dongles as 11:11:11:11:11:11, so I tried to do a
'con 11:11:11:11:11:11 spp'
which was immediately ACK'd, but 5 seconds later returns an error 14, which is
sort of a blanket error code for almost anything, like miss-matched pins,
whatever. l2ping did work before, but now is:
[root@coyote test]# l2ping -i /dev/rfcomm0 00:0c:84:00:86:F8

Progress? DamnifIknow & its the witching hour so I'm gonna go checkout some
zz's. I'm also doing 'lights out manufacturing' except what I'm doing is
sharpening a carbide tipped saw blade, using my milling machine which is run
by emc, to position a dremel with a diamond wheel in it to very precisely
grind about .005" off the face of each carbide chip, probably about .0002" per
pass as I'm using a very gentle touch. It will turn the blade 20 times, touch
each tooth in turn for about 10 seconds per tooth, 40 teeth. That operation
will be done about dawn, and it can run itself till I wake up again. :)

Thanks a bunch. I appreciate it, a lot.
