    Hi,
    
    Thanks for the hints so fare...
    
    I somehow managed to get the right logs for my problem (see below).

...and with this log your problem perhaps can be solved, see
below :-))
    
    Is anybody using an ELSA or TKR modem sucessfully with HylaFAX? Your
    config-files could save a lot of time...
    And what devices do I have to use for faxgetty and for HylaFAX? /dev/ttyS?
    or /dev/cua?

                                                    ^^^^^^^^^^^^^^
as you can see the command string contains "E0" but the modem is not
in echo-off mode after the reset-cmd "ATZE0V1Q0S0=0H";

the behaviour of modems regarding the command-buffer after "ATZ"
is undefined; some modems are just cleaning the buffer during ATZ
and don't executing all commands behind ATZ on the command line;
the echo of the commands from the modem are read by faxgetty(1M)
and faxgetty(1M) don't understand them correctly;

don't use "ATZ" in ModemResetCmds: (see also man hylafax-config(4F));
