iMac G5 and Faxing: a solution

Following a post on the 13th of February where a reader spoke of the inability to receive faxes with an iMac G5 and an Apple external modem, Jean-François has sent a solution to us.

It is very simple to receive faxes
After some tests on a machine, I realized that the modem rings, but does not pick up.
Then I thought, why not try setting it to answer after 1 ring?
Eureka! The computer receives the faxes.
I tested the fix on 2 computers which were experiencing the problem, and it worked for both of them.
But if you set it to anything higher than 1 ring, the modem does not answer.

This is not always practical as one must know when a fax will arrive, but at least this is a solution which makes it possible to receive faxes.
