I have Windows7, an X58 motherboard, and an i7960 CPU.
The external modem is a NetComm USB AM5067 56K 64bit unit plugged into
a USB3 port.
I can send out faxes directly from the computer screen with no
trouble, but I have never succeeded in receiving faxes directly to the
computer. I have configured the Windows7 "Fax & Scan" every way I can
Is the USB modem able to "answer the phone" when you attempt to have
it receive a fax ?
Were you doing that with the computer in its fully working state ?
Or were you doing that with the computer in "S3 Sleep", and your
problem is, the computer can't wake up in time to answer the call ?
On the older modems, you'd use "Wake on Ring", to get a sleeping
computer to wake up and "take a call". If the computer is
already running, and sitting idle in the desktop, then there
are fewer excuses for it not to work.
When the phone "rings" at the USB modem, the ringing voltage must
be detected by the modem and converted into an event which the FAX
software recognizes as a "call state". The software then tells the
modem to go "Off Hook" and take the call. By sending the appropriate
tone pattern, the device at the other end of the phone line, knows
it has reached a FAX machine and the protocol takes off from there.
Your problem is likely the "ringing detection" step, and you should
try to get it working with the computer awake first, before trying
to get it working with the computer asleep.
Have you tried any of this stuff ?
