Minor but not totally unexpected surprise. I imagine the "quick
train" also isn't implemented. Speed, both the compression and uplink
rates are ``more important''.

Only Linux specific would be "lcp-echo" interval and failure counts
(see the pppd man page - then try adding the "dump" option to check
what's set where), and the normal TCP or application timeouts when
the connection is "stalled".

I'm lost here - I thought you said that ATZ wasn't mucking with the
AT+MS=V90 because that +MS setting wasn't in NVRAM. If you set it on
power-up, how is it being reset AFTER that?

Some modems take "ATZ" to mean "reset to NVRAM _and_ empty the command
buffer", such that anything following the "Z" in a command is lost.
I'd suggest resetting the init-string from "ATZ" to "ATF1+MS=V90".

I'm sure of that they're different - but the "Red Hat way" I'm
referring to predates Fedora and RHEL (of which CentOS is a clone). I
think they actually started that back around 1996 (RH3.0.3). Around
RH8 (2002, which predates Fedora, but not RHEL) they started reworking
the scripts, moving them when they changed to the "Network Manager"
style tool. Same concept/style, but implemented slightly differently.

Is this because the /etc/rc.d/rc?.d/S??network is starting later than
you want/need, or because the act of bringing up the wireless link is
taking longer than it took to bring up the Ethernet interface (and
something else is timed to start after the "normal" delay)?

Not surprising - it seems that most domestic systems expect that there

Again, that's the expectation that broadband is there. For a lot of
the more developed parts of the country, it's reasonable. But out in
"the country", this may not be the case. Sure, if you need the speed
of broadband, you can probably get satellite, but you've mentioned
relatives in Vermont where that isn't practical. But likewise, the
computer stores aren't out there in the country (implying that their
customers have got broadband), and other people are more likely to be
buying on-line rather than "driving into town".

True - you could use "[ -c /dev/modem ]" which follows the link, but
the reason we're looking is because the event managing daemon (udevd
or hald, or what-ever) may not have created the link - not that the
device itself has changed or doesn't exist.

Do all of your users have /sbin/ in their $PATH? Mine don't. And
don't forget that the 'test' or '[' function doesn't know about $PATH.

That's still at least a dozen years down the pike, and a lot can
happen in that time. They may discover why the failures occur, and
can work around it.

The old question always asked by the people on the hell-desk is "what
did you change"? Or in this case, "why"? Is this another case of a
different definition of "improvement"?
