flexfax: help: received blank fax sheet

["David Zhu" <david@mezasu.com>]

Hi There,

 

I installed hylafax software(binary).
But When I send a fax, I got a blank sheet.

 

Message:
#sendfax -l ttyS1 FAXNO. /root/testfile
Trying fax device '/dev/ttyS1' ... OK
Dialing FAXNO. ... OK
Sending '/root/testfile' ...
WARNING: are you sure that this is a G3 fax file? Doesn't seem to be...

 

environment:
hylafax-i386-linux-v4.0pl2-1.tar.gz under linux (RedHat 6.0); 3Com U.S. Robotics model 0701.

 

Could you tell me why?

 

Best regards,

 

David
