We can conclude that actual modem activation is the problem.
Unfortunately, since there is a large Closed Source component,
the usual Linux troubleshooting tools cannot be applied.
Later when I'm under Linux, I'll send you a procedure to test.
But I'm not very hopeful.
The simplest route would be to shop for a Controller Chipset modem,
as constrasted to a winmodem.
