Re: flexfax: back with the problem

   David, I feel help! I'll make sure tomorrow (it's night here in
California)
that I follow your recommendations. I really don't think that /dev/modem
interfere
with anything, I already changed cua0 to ttyS0 with exactly the same
output.

   There is nothing, but HylaFAX on this modem. Also this is a server
   type machine (PS/2 mouse) and none of serial ports are used 
   (well, _should not_ be used, except modem :)

    I just followed RedHat Linux HOWTO for HylaFAX, it said to make
    a link /dev/modem to /dev/ttyS0... I can certainly remove it

    I put SessionTracing 47 in etc/config.ttyS0, but nothing has changed
in
    log/c...... file. Am I missing something?

    The last modem I got is on the list of the best recommended modems 
    (Multi-modem 2834) and it should work with hardware flow control
using
    default configuration (I had it in rpm distribution), I thought that
    if it works for everybody, it will work for me too :)  
    However, I have no idea whether I used
    right cable and how could I possibly create loop back. Everything is
    standard, RJ-45 going from a modem's "line" connector to a wall...  
    Also I have tried several different lines to make sure that I do not
    have line problems.

    I'll try to switch flow control though I did it before already with
    no change (for USR V.Everything, now dismissed :)
    It just occurred to me that I may have noise level not adjusted for
    the modem, I saw something about this in docs...
    I'll appreciate any comments you may have.
  
    Thank you, Michael
