flexfax: hylafax server/modem problem

["Oliver Carl" <ocarl_b@hico.ch>]

Hello list

I try set up Hylafax as a small company fax server. Sending is O.K.,
recieving won't work. If you can - please give it a try. I am trying to
proove, that OpenSource is the better choice...

I put together a HTML document with extensive information
 http://www.hico.ch/hyla.php ) - the following is a shortend version.

thnx in advance
Oliver

OS: SuSE Linux 5.3 (Kernel 2.0.35)
Hylafax 4.0pl2
Modem: Olitec SelfMemory 33600 (supports Class2)

After doing some setup, correcting daemon and TSI setup, I am now able to
send faxes perfectly.
Recieving works basically (...not) - the problem is that I get tons of "bad
lines" or the transmission ends long before the page end (see log 27, where
only the header was transmitted - the best recv I got so far). The
percentage of bad line is rather reproduceable, obviousely depending on the
document, not the phone line quality (which should really be perfect in all
cases).

I think (?) I had to put "ModemRate" to 19200 when using XON/XOFF. I now use
RTSCTS successfully sending with 38400 - there is no change in recv'ing. I
went back to 19200 now, because I think it works better.

I have tried to reverse the "ModemRecvFillOrder" - no change.

Set sender's bits/s down to 4800, resolution to high (7.7lines/mm) - no
change.

I think, it might be that the modem pretends to have some capability, it
actually has not (or that is not implemented correctly). On the other hand,
I have tried two rather different communication partners - one reports "not
sent" (and hyla says "bad lines"), with the other one hyla says it recvd
only a few lines (no status from remote partner available)...

Is there is some communication problem on the serial line?

I put the required "PercentGoodLines" to 1 - I got a few blank lines (from
fax partner of log 20).

I tried to change Class2RecvDataTrigger from "" to "\022" and "\021".
