Subject: cc: Mail and Alcom DID Fax Integration
Organization: NETLAN, Inc.
Date: Tue, 8 Sep 1992 23:02:30 GMT
X-Mailer: PSILink (3.2)

I have a site where we are using the Alcom DID Inbound Router to receive 
faxes.  These faxes go to an MHS hub which in turn forwards them to a 
cc:Mail post office, thus placing them in the correct users' mailboxes.  
This works great except for one thing:

When the cc:Mail user gets the fax, the cc:Mail message header does not 
have the information that the message is a fax (PCX) and thus when the 
user attempts to view the fax item, the PCX viewer is not called, 
resulting in a garbage display.  So far, the best solution I have for 
this is to have the user save the PCX fax image to a file and use a 
separate program to view and print the file (not very user friendly).

There must be a portion of the cc:Mail header that marks the item as a 
fax - does anyone know what it is and how I can "flip the switch?"

Anyone else have experience with this?

I await the vast currents of collective knowledge to bring me an idea 
(via email, please - I'll post a summary to the list).

Many thanks,

Al

Assuming you want to use as few phone lines as possible,
and you want people with regular faxes to call your system,
wouldn't you need a smart replacement for uugetty to route
the connection to the appropriate service?

Not that I know much about getty, but I suspect that switching
to different services on the fly based on
--> incoming connection messages from the modem <--
will require much smarter serial port handling.

I know my trailblazer won't work very well with my uucp
if I have incoming status messages turned on, because
of the "babbling to itself" problem that sometimes occurs when 
the system starts mistaking modem return codes for login attempts.

I can't expect a fax machine calling in to log in to an
appropriate user account, and I'd sure like to use
a combined fax modem for bi-directional modem and fax service
at the same time.  It'd make sense not to have to pay for extra modems
or phone lines.

I don't know how netfax handles this problem, if it does.

Any thoughts out there about this?

I'm working on a FAX handler for a MultiTech MT1432 which claims to
be Class2 compatible, and have a couple of queries which I hope someone
can answer.

1) When receiving a FAX image from the remote end, the pages often terminate
   prematurely (with the expected DLE/ETX and +FPTS ...), and the handler
   gets a +FHNG:73.

   Does anyone know why I might get the correct end of page sequence - possibly
   in the middle of a document - immediately followed by a hangup ?

2) Is the T.30 timeout (FHNG:73) set by the Class2 spec or should it be configurable ?
   If the latter, any thoughts on how ?

3) Can anyone send me a complete copy of the T.30 and TR.29 specs ?

Thanks in advance for any help you can give.

The differences are significant enough that software won't work 
without modification.  Just how extensive will the modification be? 
Well, to some extent that depends on how many of the Class 2 
features you use.  The names of virtually all the commands and 
parameters were changed, but that's "just syntax".  A number of 
parameters were added, and the behavior of a few things is changed 
(error correction mode is completely different, for example).  The 
biggest change is in the fax transmission process, where different 
DLE codes are used to indicate the disposition of a page, rather 
than +FET commands.  My guess is that software can be adapted from 
pre-Class 2 to real Class 2 with less than a man-week of work, if 
you use just the basic operations.

Surprising and this might sound, I have had no problem sending
faxes to Russia, Ukraine and Norway with my Gateway 2000 Telepath.

With my setup at home, my modem will choke on a V.32bis connection
to the Gateway 2000 BBS (Cleveland to somewhere in South Dakota),
but faxes has been no problem no matter where I have sent them.

We have a Canon Fax machine at work that has problems connecting
to Russia, which was why I tried the Telepath.  I didn't expect
it to work, but it did.

    Isn't this after the login sequence? These shells are defined in
    /etc/passwd, and the decision is made which shell to use based on
    what machine/account is logging in. Like you said:

    Well, if the remote fax was smart enough to respond properly to the
    login sequence, the problem of dial-in fax machines would be moot.
    Anybody make a fax machine/modem with programmable chat scripts? 8-) 

    Seriously, the ability for (uu)getty to recognize different modem
    responses is the key to successfully negotiating the FAX/Modem
    portion of the handshake. This must happen before getty hands off 
    to the login process, as this handshake is a modem function, not a
    login function.

I would suggest that you find a fax software package you like and
ask what types of modems it supports. It's quite likely that there
is no UNIX fax software available for the Intel.

Note: I am always mentioning Class2 as the defacto Class2 or ersatz Class2
      since the standard has yet to pass!!

I have some Class2 fax software we have written and it works just fine
with the Rockwell and Sierra chipsets.  Taking into account some really
sloppy code on the part of the chip makers since they don't seem to watch
the fax carrier very well and sometimes don't return +FHNG when it
is hung up.  Oh well that is another huge story.  Does EXAR have some
sort of a difference between it and the normal Class2 from Rockwell/Sierra?

It almost always hangs up on me after the first page is sent.

PS: Any software vendors can contact me for the preliminary Fax/Modem
    command score card which will show you the variety of responses to
    certain Class2 commands.
