flexfax: Strange problem : modem capabilities not reported to fax machines

[Andrea Albarelli <andrea@side7.it>]

Hi, I have got the following strange problem :

I have an Hylafax 4.1beta2 on Linux 2.2.14 with a Zyxel 2864i
I forced in config.ttyS0 the capabilities of my modem with :

Class2DCCQueryCmd:      "!(0-1),(0-5),(0-2),(0-2),(0-1),(0-1),(0),(0-7)" 

So far so good, please note the ECM ( error correction mode ) capability
enabled.

Now, if someone send a fax to me, for example with sendfax, he see the
following capabilities reported :

Apr 03 21:39:02.65: [ 1990]: REMOTE best rate 14400 bit/s
Apr 03 21:39:02.65: [ 1990]: REMOTE max page width 2432 pixels in 303 mm
Apr 03 21:39:02.65: [ 1990]: REMOTE max unlimited page length
Apr 03 21:39:02.65: [ 1990]: REMOTE best vres 7.7 line/mm
Apr 03 21:39:02.65: [ 1990]: REMOTE best format 2-D MR
Apr 03 21:39:02.65: [ 1990]: REMOTE best 0 ms/scanline   

But if I send a fax to a fax machine with ECM enabled I see this result :

Mar 16 09:22:35.82: [  903]: REMOTE best rate 9600 bit/s
Mar 16 09:22:35.82: [  903]: REMOTE max page width 1728 pixels in 215 mm
Mar 16 09:22:35.82: [  903]: REMOTE max unlimited page length
Mar 16 09:22:35.82: [  903]: REMOTE best vres 7.7 line/mm
Mar 16 09:22:35.82: [  903]: REMOTE best format 2-D MR
Mar 16 09:22:35.82: [  903]: REMOTE supports T.30 Annex A, ECM
Mar 16 09:22:35.82: [  903]: REMOTE best 10 ms, 5 ms/scanline   

Note that in this case ECM is reported.

Because my fax doesn't report ECM ( tough I thik I enabled it ) the remote
machine doesn't use it and I get many errors ( poor line quality, I'm in Italy )

Why on the earth hylafax doesn't report all my capabilities ? Is it a problem
with +FIS or FCC ? 

Please help me !

My config file is the following ( cutted out uninteresting parts ) :
