Look on ebay for thin stylus - a few cents to <$20 seems to cover the range.
I got 10 for $4 when I got my tablet and am using my 4th one after 3 yrs.

How about a toothpick?
 
Too small, maybe a chopstick.

I'll get to work on it right away.

A toothpick won't work.

I think that's far better than Motorola being purchased by Arris.

Shudder... 2-wire was so much fun when AT&T rolled DSL into Lake County.
They brought guys over from Santa Rosa to do some of the installs, and I
think they cleared out the Santa Rosa dumpsters of all the old 2-wire boxes.
(but we've chatted about that already.)

I had phone service from Mediacom for a while. Now that portability works
so well, you can change VoIP telco providers as easily as gas stations.
I thought the CableCo voice was a "good thing" because it used a separate
channel, just like the XfinityWiFi. No impact on your modem speed, no
collisions, better voice.

If they reuse returned modems, that might take a long time.
Mediacom didn't even rebox the modems. They'd give you one in a plastic
bag.

IPv6 was a real headache for my son's new XBoxOne. You couldn't disable
IPv6 in the TG862G, but it didn't work well, or XBox didn't, or something.
On Ubuntu, I see that connections to some of the major sites are IPv6.

True, but Motorola is far from perfect. Every time they buy a modem
company, the first thing that happens is the pipeline is crammed full
of rejects, returns, refurbished, and junk modems for about 3 months.
I think the company they bought counted their backlog of repair jobs
as shippable inventory when the company was appraised, and Motorola
just shipped everything.

Yep. I saw the dumpster crammed full of failed and rejected 2-wire
power supplies delivered from the local AT&T yard. Why AT&T kept so
many dead power supplies around their yard will remain a mystery.
 
>> problem is if they order phone service from Comcast,
 
Well, I lied a little. While the Arris TM722G and TM822G telephony
modems are not listed as "retail" on the Comcast web site, Comcast
will activate them if you scream or complain loudly. They can be had
for $30 to $70 on eBay.

Comcast really wants to be a phone provider (without all the telco
common carrier restrictions) and is doing their best to become the
carrier of choice. Of course, that doesn't include remembering to
supply backup batteries for the modems and gateways, but I'll forgive
them for trying to gouge and extra $35 from those that complain. If
they keep up such practices, they may achieve their goal of emulating
all the bad parts of AT&T.
 
The cable telephony modem, which uses a separate channel is the better
way to do phone for the reasons you indicate. Another advantage is
that the jitter on the telephone RF channel is quite good, while the
jitter on the Comcast data channel is variable, apparently depending
mostly on channel loading. I'm on Comcast but using Future-Nine for
VoIP on the data channel. There are plenty of dropouts and garble but
at $6.25/month, I won't complain (much).

I don't know what Comcast does with their returns.

Chuckle. I should have predicted what is happening. Comcast cranked
up the speed for home users about 2 weeks ago. I'm seeing 90
Mbits/sec down and either 6 or 12 Mbits/sec up for both IPv4 and IPv6.
Both are obviously rate limited. However, that was 2 weeks ago. Now,
I'm seeing the same 90 Mbits/sec for IPv4, while IPv6 has dropped to
about 40 Mbit/sec. What seems to be happening is that the new Windoze
10 machines favor IPv6 if it's available. Comcast seems to have some
kind of IPv6 to IPv4 gateway for those web sites and servers that only
terminate with IPv4. The Windoze 10 machine favors IPv6 for
everything, so the gateway is probably getting swamped by the Windoze
10 traffic. I've again had to turn off IPv6 in some customers routers
to maintain performance as the congestions seems to produce some
dropped packets.
 
Tomorrow, I do a service call for a dialup customer. I wonder if I
even remember how to setup and use dialup internet?

I usually retest URLs that I post, just to make sure they are still live
(Jeff had a discussion with someone else who needed to take a little time
out on that issue, recently.)
 
I discovered that my home IPv6 wasn't IPv6-ing.
I used my set of URLs:
http://ipv6-test.com/ (look at the "api" tab)
http://test-ipv6.comcast.net/
http://speedtest.comcast.net/
 
hmmm...
Oh, right! Someone suggested that IPv6 has no stateful filters, and it
would be impossible to block inbound attacks.
Is that true?
I left "Enable Router Advertisement" turned off, which killed my external
IPv6 while I investigated, and I guess I never finished investigating.

Unfortunately, long-press on the AM/FM bouton will not work for this problem. The PLL IC could be SANYO LM 70XX, or Matsushita AN7273, AN7470.... Let me find out later, then, see what I can do by modified the on board HW setting. I will try to down load the service manual again and again.... Thanks.
