    Did you use the Linux patches? Such as the ones available at
    http://cirl.meei.harvard.edu/hylafax/patches? And did you successfully
    run faxaddmodem, and install a faxgetty entry in /etc/inittab?
    What does faxstat say?

    Looks like the wrong place to me: look at this:

    I take it you have to dial 9 as a prefix: this should be done inside
    your dialrules.ext file, not as a hand-added number, or it will screw
    up logging of the fax's real phone number. Moreover, it should 
    add "9,", not just "9", to make sure that it dials 9 and waits for
    a dial tone.
    
    Your local fax number should *NOT* have the 9 in front in the config
    file.

The "9" is unrelated to the problem. The main problem is:
why is the modem's echo still turned on? The log in the
original mail showed that the first command sent down to the
modem caused a "Timeout" and echo remained on:

    Apr 19 16:02:18.61: [11891]: DELAY 2600 ms
    Apr 19 16:02:21.22: [11891]: <-- [15:ATE0V1Q0S0=0H0\r]
    Apr 19 16:02:26.22: [11891]: MODEM <Timeout>
    Apr 19 16:02:26.22: [11891]: <-- [5:ATM0\r]
    Apr 19 16:02:26.48: [11891]: --> [4:ATM0]
                                 ^^^^^^^^^^^^

With echo turned on faxsend(1M) can't understand what is
going on; it's awaiting something like CONNECT or BUSY
but no echo of the dial command it has issued.
