It seems that hardware is sleeping.
I think the "digital test" test the UART emulator in the ltmdmobj.o
and it does not test hardware part.
This may be a problem caused by ACPI.
If it is true and you can not change BIOS setting, it will not work
under FreeBSD-4.x.
I made a patch which adds call_func(1)/call_func(9)
before vxdPortOpen()/vxdPortClose().
(I'm not sure this can solve the problem though.)
Since my modem is older one, I can not reproduce the problem to test it.
