hello all,
I've been using hylafax 4.1 on suse 6.3 with 3Com US Robotics 56k faxmodem
(1998).
In most cases it seems fine but I often get phase C errors.
Now looking through the archives I've seen that lowering to class 1,
reducing the max baud rate & using some Class2NRCmd command can help for
older models. I've tried those but with no luck so far.
Any ideas or do I have to get my self another modem?

Is there perhaps some minimum configuration which works with all faxes?
(just want it to work).


Here are few dumps which will hopefully give somebody a clearer picture of
what's going on, must say they don't help me much 8-.
