Got  it!  

In my chat(8) script, the initial expect sequence was:

  ''     '\rATZ'

No recollection of why I have the '\r' there -- lost in the mists of
time and it has worked that way on sevral versions of Slackware and
different computers.

Changed it to:

  ''     'ATZ'

and everything proceeds as it should, dialing, logging into the ISP
and passing control to pppd. I have *no* *idea* why '\r' works on
bogus (desktop) but not on roadgrime (laptop) with the same model of
modem. 

Now I have another problem but it's nothing to do with hardware.  It's
something to do with my route setup.  I've had no trouble with routes
using the laptop on my LAN, on cabled broadband at a friend's or at
wifi points.  But successful connection of ppp0 to my ISP's host
leaves me cut off from all the net but the machine that hosts the
other end of ppp.

Well, a different problem.  The USB/serial tech is working.

Thanks for your attention, OG.
