Lately I stumbled upon a solution to a problem that had plagued me..

The dreaded "No response to MPS or EOP ..." error.. ARGH!!

I had been trying to figure it out for ages! Anyway, no guarantees but

I do hope it works for everyone else concerned.

This solution should shed some light on the whole problem..

I have tried many different modems and had the same problems

with both class1 and class2 modems from netcomm and banksia

(very common in australia.. the firmware seems to be rockwell / conexant).

As usual these modems worked fine from other fax software.

Well I had noticed 1 or 2 users stating that if they used sendfax

with the -1 argument that it solved this problem. The question

arose ... why? .. and how the hell do I implement this from

a win95 client!?.

After reading the advanced settings page (*** READ IT ! ***):

http://www.hylafax.org/setup-advanced.html#Class2Liars

I realised this... when HylaFAX queried my modem about its

capabilities, it didn't understand what my modem returned.

HylaFAX would query the modem with AT+FDCC=?

and my modem returned : (0,1),(0-5),(0-2),(0-2),0,0,0,(0-7)

HylaFAX seemed to lose it when the modem says 0,0,0,..

If you bother to read the link above you will understand that you can

correct hylafax.. by forcing it to use the correct options.

That explains why they worked fine from other fax software!!!

here is what I changed in /var/spool/fax/ttyS0 :

Class2DCCQueryCmd: "!(0),(0-3),(0-2),(0-2),(0),(0),(0),(0-7)"
which forced it to use low-res, <= 9600 Baud, 1-D compression,

no error correction, and no Binary File Transfer...

(I recommend trying this configuration, if you have a lot of trouble)

After which I have had no problems!

--------------------------------------------------------------

Here is the file /var/spool/fax/ttyS0

...

ModemRate:  38400  # max rate for DCE-DTE communication
ModemType:  Class1  # use this to supply a hint .. class1 seems to work better for me
#ModemType:  Class2  # use this to supply a hint
ModemFlowControl: xonxoff  # XON/XOFF flow control assumed
#ModemFlowControl: rtscts  # XON/XOFF flow control assumed

#...... .. some users find rtscts fixes their troubles

ModemATCmdDelay: 0
Class2DDISCmd: AT+FDIS
#Class2DDISCmd: "" # disable pre-dial DIS command hack

#ModemNoFlowCmd: AT&K # disable flow control cmd (default .. is this a mistake?)
ModemNoFlowCmd: AT&K0 # disable flow control cmd (my modem uses this)

###Class2DCCQueryCmd: AT+FDCC=? # query for modem capabilities (default)

Class2DCCQueryCmd: "!(0),(0-3),(0-2),(0-2),(0),(0),(0),(0-7)"

here is a log file with the MPS and EOP errors
