MODEM RING-IN
Everyone knows that a PC system can be used as a fax machine to send or receive
fax messages. But most people still use fax machine to receive their messages
because it is not practical to have the system powered on all day long waiting for
the incoming messages. Now the problem can be solved by using this mainboard. It
can be triggered by a modem ring-in signal. When you have a
external
modem
installed, you can leave the PC system power off. Whenever there is the incoming
message, the PC system will be triggered by the ring-in signal and wake up
automatically to receive the message for you. From now on, you can tell your PC
system to receive the fax message for you.
