vgetty/pvftormd problem
I'm using Debian 'stable' mgetty-pvftools-1.1.27-4.1 on one machine and
'testing' mgetty-pvftools-1.1.28-2 on another. On both, when I prepare
a message from a wav file it produces static like noise when my modem
answers.
My modem is a Sportster Vi 33600 Faxmodem.
It records incoming perfectly. I can take an incoming message and
play it back as the standard.rmd and it sounds great. If I take the
same message and use pvftools to make it a wav file it sounds great.
If I take that wav file and transform it back into rmd, it is only
noise.
rmdfile on incoming messages shows US_Robotics 1, 8 bit, 8000 samples.
I use wavtopvf and pvftormd US_Robotics 1 to recreate the rmd from the
wav and rmdfile shows the same information.
The same problem (noise) occurs if I use a wav from another source,
use pvfspeed to make the speed and bits correct and pvftormd to
prepare the rmd file.
Is this modem a known problem? Is there a known problem with
pvftormd, and can I work around it? If not, what modems currently
available on the US market are known to work with Debian, vgetty &
pvftools?
Thanks.
