flexfax: Problem with '- F' option of 'sendfax'

["Chemisov Serg" <chek@ns.sirena.ru>]

		Hi ! 
 I  use :

Sys: P-100mhz, 16Mb Ram
OS:  FreeBSD-2.2.1
Ver: hylafax-v4.0pl2, tiff3.4
Modem: ZyXEL U1496

I would like to change Tag Line on outgoing faxemiles using " -F " option
of sendfax program. 
As I see it is possible when " TagLineFormat "  variable
set as " %%j "(user-specified job tag)  in modem config  file.

When I trie use  '-F' option of 'sendfax' , there is no changes on 
outgoing faxemiles
(Example):
#sendfax -n  -d "81521756" -F "%%m"   file

And when I use " -F " before " -d " I have next error :
#sendfax -n -F "%%m"  -d "81521756" file
503 Permission denied : no write access to job parameter USETAGLINE
#

The " TagLineFormat " variable set as '%%j' .
Explain for me please where is my mistake.

Regards.
