Ok, Marv, I *think* I have the parameters set up correctly (?) on my
Ubuntu system. Still get the hang-up after a few seconds of mutual
(presumably) handshake. From the concerns you sent (below included)
what is the (your) recommended course of action?
Thanks,
Henry
p.s. the modem tried to dial up before I was logged in... I take it
this would not be a usual event?

Henry,
The info below may/maynot be cogent to your US robotics Controller
chipset modem.
Unless a failure is encoutered, assume it is not.
There is alternate support for the 11c1:0620 Agere modem,
but a bit more difficult to implement.

Subject: kernel 2.6.25 serial port bug [continued]
To: Marvin Stodolsky <marvin.stodolsky@xxxxxxxxx>
Cc: btech@xxxxxxxxxxxxxxxxxxxx
Another thread discussing the kernel 2.6.25 serial port bug has
appeared in the minicom discussion group,"minicom 2.3 (which termcap)
and kernel 2.6.25.1 (DTR)". The original post:
http://lists.alioth.debian.org/pipermail/minicom-devel/2008/000872.html
implies a fairly specific way to detect the bug (and find the faulty
code) using minicom. The second post:
http://lists.alioth.debian.org/pipermail/minicom-devel/2008/000873.html
states, "The 8250 drivers in versions 2.6.25 through 2.6.25.7 are
broken. 2.6.25.8 (and later) works." I don't know R.L. Horn except
through his posts on this topic, but he seems quite knowledgable.
If any of the developers or, worse yet, the modem manufacturers have
emulated the faulty 8250 code it might explain the difficulties and
inconsistencies they're encountering under 2.6 kernels. I've also
noticed a few users reporting problems setting up their wvdial init
strings; maybe some of these are related to the problem described in
the first minicom post above.
A correction to my previous message (shown below): minicom is a
text-only *serial terminal* program, not a *browser* ... DUH!.

or Jacques posted a message about the kernel rejecting non-GPL
modules; now the kernel developers have introduced a bug into the
serial driver in at least some of the 2.6.25 kernels! I stumbled
across three threads in the minicom discussion group. They all seem
to be the same problem, but the "subject" evolved as its nature
became better understood. Here are the "original posts" of the threads:

it. I vaguely remember someone with a *hardware* modem reporting
difficultly configuring wvdial; maybe it was due to this bug.
