Re: [hylafax-users] mps,rtn, canon fax machines SOLVED

Hi!

I played a lot with parameters and statistics, and found the following:
Since a half year (and 962 files in the log dir) if I connect to a Cannon
fax with the v.17 modulation the transmission fails!!!
No matter if the coding is 1/2D or the speed 9600-14400 or the RTNHandling
set to Ignore.
The remote end gots nothing. I have either MPS/EOP or RTN related errors or
absolute no errors (RTNHandling=Ignore)

The NSFs here:

I modified the source a little bit so findBRCapability (in Class1.c++) not
allows the V17 modulation if the remote end is Canon.
(patch below)
The training now accures at v.33 and everything is fine!

Comments?
