[hylafax-users] fax broadcasting with Hylafax

["Vlad Shalamov" <shalamov@sympatico.ca>]

Hi List.

I'm doing fax broadcasting and my main goal is increase fax rate as much as
it's possible. I did some optimization of my Hylafax server (4.1.2 on RedHat
7.3, faxboard - RocketModem II) and I'd like ask has anyone done the same
task.
I've setup the following parameters:
MaxDials: 2
MaxTries: 2
NoCarrierRetrys: 0
ModemWaitTimeCmd: ATS7=20  (special thanks to Giulio Orsero and Lee Howard)
ModemResetDelay: 1500
Also I changed bin/ps2fax so it always generates tiif32d (device=tiffg32d).
I tried with tiff4. GS is doing well and file is about 20-25% smaller than
with tiff32d but when I'm sending it to remote fax I get an reject error:
..........
Jun 24 10:25:48.14: [ 1970]: REMOTE best rate 14400 bit/s
Jun 24 10:25:48.14: [ 1970]: REMOTE max page width 1728 pixels in 215 mm

Jun 24 10:25:48.14: [ 1970]: REMOTE supports T.30 Annex A, ECM
Jun 24 10:25:48.14: [ 1970]: REMOTE best 20 ms, 10 ms/scanline
Jun 24 10:25:48.14: [ 1970]: USE 14400 bit/s
Jun 24 10:25:48.14: [ 1970]: USE 20 ms, 10 ms/scanline
Jun 24 10:25:48.14: [ 1970]: SEND file "docq/doc12.ps;31"
Jun 24 10:25:48.14: [ 1970]: REJECT: Document is not in a Group 3-compatible
format (compression 4)
..........
My questions are: "Is it anything else I can change in order to increase fax
rate?" and "Is it possible to fix reject error for tiff4 or it depends on
remote faxmachine?".

Best regards,
Vlad Shalamov
