Hi,

I just wrote a wrapper script for /usr/bin/fax that will automatically
convert incoming faxes to multi-page compressed postscript files and e-mail
them to postmaster (or whoever you specify as MAILTO in /etc/efax.rc).

I find it pretty handy... and wow, efix is a great program!  Converting G3
to postscript in just 36k :)

You need the "metamail" package installed in order to send the
MIME-encapsulated mail with my script.

Maybe this can go into a later version of the Debian package.  You just need
to run the script in place of "fax answer" in /etc/inittab.

Have fun,

Avery

Ed,

Here is a script which Avery contributed. I'll put it into the next Debian
revision of efax. I just thought I should seek your input on what to name it.
Any suggestions?  Maybe faxreceive ?  That choice would be compatible with
the currently used commands (see the list of what Debian already has below).

Regards, Dirk

Hi Avery,

Here's what Ed wrote regarding your wrapper script. It might be best to
proceed along the lines he suggested as the values needed are easily
available from within efax.

Regards, Dirk

Hi guys,

I've re-written my fax-to-multipage-postscript-email conversion script to
use the NOTIFY features in the 'fax' script.  In doing so, I found some
problems with the NOTIFY feature itself -- it doesn't work if I use the "fax
receive" command, but only with "fax answer", and even then, only the _next_
time I run "fax answer" after receiving a fax!

This is pretty weird.  Below, I'm including a patch for the fax script that
makes it run NOTIFY even for fax receive, so it will work in my setup (where
I can't use fax answer... long story).

I also include my new and improved efax.convert script, which takes $REMID
$FILES on the command line.

Have fun,

Avery
