Sorry to return back to this topic, but I still have some small problems
with mgetty/sendfax.
I am using the ACEEX 1496 faxmodem under Linux .99.8 and mgetty/sendfax
0.13. After enforcing the hardware flow control (mapping the ioctl calls to
tc{get,set}attr), sending faxes is working perfectly. The only problem is
faxrec. The received faxes are legible (somehow), but many lines are corrupted;
even g3topbm reports a problem of premature EOF, so I had to hack it in order
to get something at least. I fear the problem might still be the flow control,
but dunno...
Another surprising fact is that sending a fax at 14400 bps sendfax consumes
only about 10% CPU (80386, 33 MHz), whereas receiving at 9600 mgetty consumes
something in the region 70-95 % CPU !! I seem to have noticed that even during
the fax receive, OPOST and OCRNL are active; is it quite OK?
Would appreciate any hint, thanks in advance,
Tom
