Well, I also have very bad quality phone line. In fact, this caused
Microcom, which I used, to hangup on me (or even worse - to freeze,
so that *I* have to hangup to untie the line) at least once in 30
minutes. Microcom TechSupport was NO help at all.

So I switched to ZyXEL. And I found - they're willing to help, and
they do ship free upgrades... Every darn modem firmware has bugs.
Period. But not every manufacturer/distributor is willing to
acknowledge this and send free upgrades!

Some numbers at this point might help. My ZyXEL (with LCD) *tells* me
the S/N ratio... And the experience shows: when S/N drops to 21, or
below - the modem drops from 12Kbps to 9.6Kbps... Sometimes, when
lines get real noisy, it gets worse...

Here you're certainly right. I wonder, what numbers they got on
your line, though...

Well, it's certainly an unpleasant experience, but what would you
expect him to do?

Of course! It's much better, when a piece of equipment dies clearly,
than when it just drops a thing or two on you once in a while, and
normal tests reveal nothing!

I bought ZyXEL, expecting it to be a good modem, with bugs and
potentials, and with TechSupport willing to help, fix those
bugs and ship the upgrades/fixes free. I found that. I'd
buy another ZyXEL. Probably I will, since my other
modems (old trash Microcoms) work as good as
your ols ZyXEL, even worse (:-).
