"FaxBack" files in PROCOMM PLUS for Windows V. 2.x Host
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When PW2 sends a Fax, it must first convert each page of the file being sent to
a Fax graphics image.  This is done by printing/converting each page of that
file to a PW2 Fax driver as one would print to a Printer driver.  Whether you
send a Fax using PW2 from within PW2 or from another application using PW2,
each page must be printed/converted to the proprietary Fax graphics image
format used by PW2.  The output of this printing/conversion process produces
pages named [filename].001 for the first page, [filename].002 for the second
page, and so forth for all pages, and a file named [filename].FAX which is an
index to these pages, all part of [filename].  (Additional files may also be
created, but more on that later.)

Likewise when PW2 receives a Fax, the received pages are created as
[filename].001, [filename].002 et al; one for each page, and a [filename].FAX
file which is the index file to the pages making up the received Fax
[filename] is also created.

For our discussion here a "FaxBack" file is actually a "set" of files, a
"fileset" making up a single unique and complete Fax whose base filename we
will call [filename].  This "FaxBack" fileset is that group of files which are
used by the PW2 scripted Host's FaxBack function when the Caller to the Host
requests that the Host send to that Caller the specific FaxBack file listed in
Host.  The Host script actually lists as available only those files in its Fax
directory which end with the extension "FAX".  Those files, we'll call one of
them [filename].FAX, are only the index files to the pages that, with itself,
make up the full "fileset" known as the Fax [filename].  When we use this Fax
"fileset", called here the Fax [filename], as a Host FaxBack
selection it becomes for our purposes here the FaxBack fileset [filename].

Let's restate this a slightly different way so we are absolutely clear as to
what we are talking about.

A PW2 "Fax file" is not a single file.  It is a set of several files (at least
two files) all dealing with that specific Fax [filename].  There must be a
[filename].FAX file.  This is usually a 54 byte file which is the index to the
graphics "pages" of that particular Fax.  Accompanying this [filename].FAX
index file are the graphics pages of this Fax [filename]: [filename].001 and
perhaps further pages [filename].002, [filename].003, et al, one for each page.
Let's call this the "fileset" for the Fax named [filename].  At various points
in the creation of a Fax to send there are other files which may be thought of
as being, for a time, a part of this "fileset".  Files with the extension HDR
are created for the transmission.  These are the single line at the top of a
Fax page in very small type which contain the identification of the Sender, the
page number, and such.  (As set by you at Fax Options, Send Options, when you
select what will be included in the header.) A file with the extension CFG may
also be created.  In some cases a file named COVERnnn may be created as part
of this Fax "fileset".  But these and others are eventually dispensed with,
separately stored or deleted, and are not a part of the Fax fileset which makes
up what we are here calling the "FaxBack fileset".


There are several ways to create a "FaxBack fileset" or to make use of existing
files as PW2 "Faxback filesets".

If you have received a Fax with PW2, then PW2 will have created a set of files
in your \FAXRECV subdirectory which include the [filename].FAX file which is
the index to the pages of [filename], and the files for the graphics pages that
make up [faxname].  These latter, one for each page, will carry the name
[filename].001 (for the first page), [filename].002 (for the second page), and
so forth.  The [filename].FAX and [filename].001 (.002, .003, et al) make up
the Fax fileset [filename].  Just copy this Fax "fileset" to the subdirectory
which you will be using as the FaxBack directory (the directory named by you
as your Fax directory in Host's HOSTUTIL Host setrup script), and you have a
FaxBack fileset!

If you have sent a Fax from within PW2, and if you have _not selected "Delete
pages after send" at the Fax Options, Send Options dialog of Setup, then your
sent Fax (the [filename].FAX and its page(s) [filename].001 etal) has been
stored by the program in the FAXSEND\ARCHIVE subdirectory as a Fax "fileset".
Just copy this Fax "fileset" to the subdirectory which you will be using as
the FaxBack directory (the directory named by you as your Fax directory in
Host's HOSTUTIL Host setup script), and you have a FaxBack fileset!

To create a _new_ FaxBack fileset is not a difficult task. One first sends a
Fax using PW2, either from within PW2 itself, or from another application
using the PW2 Fax printer driver.

You can then select at Fax Send, Time & Options to "Send to file".  This
prevents the Fax from being sent now, but creates the "Fax fileset" we have
been discussing, and which can be used as a "Faxback fileset."

If you select instead to send the Fax at a future time and date, then the "Fax
fileset" will also be created, but the Fax will be stored as a Scheduled Fax.
You can, at the Connection Log's Scheduled Fax dialog, Delete the Fax as a
"Scheduled Fax", and what is left is the Fax "fileset" which can be used as
a "FaxBack fileset".

Yes, you can rename a Fax fileset.  All of the files which make up the Fax
"fileset", the [filename].FAX and its accompanying pages [filename].001 et al,
must be renamed, with the same extension, to a new base [filename].

I hope this clears up just what a FaxBack is, and how to create one.  If this
text file doesn't provide the answers you need, let us know where it falls
short, and we'll update it promptly.
