  2.  How do you view incoming faxes?  Do fax boards come with the

Hi All,

Is anyone else using WinFax Pro 3 and the USRobotics Courier HST
16k8 DS FAX?

I have a problem where received faxes are slightly corrupt, in a
page a few small strips of the image are inserted above their
proper position, sometimes they are duplicated. This has got to be
some sort of buffer wrap around problem with Winfax or the HST.

The problem seems worse on fine resolution faxes but that's
probably just due to the additional amount of data. I'm using a UK
spec HST I would be interested to hear from any one with a similar
problem (or lack of problem), especially with a US spec HST as I
presume that's what Delrina would have tested (if they tested at
all).

Cheers Terry...

Sorry if this is an old and boring question but...

Is it really necessary for a modem to have FAX support built-in in order
to use it for PC-based FAX?  In other words, is there software available
the allows a standard modem to communicate with a FAX machine?

If not, then is anyone out there using a TELEBIT T3000 as a FAX?
I have a T3000 that is probably about 4 months old that I don't think
has any special FAX support (there's no mention of it in the manual).
I understand that there is an upgrade rom for the T3000 that adds FAX
capabilites.  Anyone out there used this?

Thanks in advance...

Not really, but I may be wrong - anyone care to comment?

The problem is that the initial protocol for startup involves
full-duplex synchronous error-checked transmissions at various baud
rates (this you could do), then switching to a half duplex protocol. The
standard modems do not handle half duplex.  The only modem protocol that
comes close is the V23 (1200/75) in which you can ignore the back
channel and then turn the line around so that the answerer becomes the
originator and so forth. (At least this used to be possible in sync
comms vith 1200/75 modems, I haven;t seen this mode in quite a while).

The 2400 baud basically splits the bandwidth into 2 x 2400 baud
channels, one in either direction.  Fax requires 1 channel, 2400 baud
(minimum) and up to 14.4k (now - used to be 9600), that is then swapped
from end to end.

The above msg implies to me that you want two pieces of software to access
the same device at the same time.  /TILT/.  On the other hand, there is a
product called The Complete Communicator which is able to take FAX, Modem,
_and_ voice calls, treating each differently.  Unfortunately, its modem is
still only 2400 (FAX is 9600), and the way it identifies the call type is
not completely automated (incoming callers must press a touch tone
sequence to switch to other than the default, which can be any of the
three call types).  I have mine set up to default to voice, but my voice
message (my voice) says to press 3-2-9 if you are sending a FAX.  If I have
modem software running, I can have another code to switch to it.  The software
for this board is a TSR.  This means you can run your BBS in the foreground,
with CCOM defaulting to answer to the modem.  Your voice answer would be a
quick "Press x-x-x for FAX, now, else here's the modem".  Of course, this
means that someone sending you a FAX cannot simply have their FAX call you
to send; they've got to manually hit those keys.  You could default to the
FAX, but then callers to your BBS would have to manually send tones to
switch to the modem.  And, of course, this is a single line device, so you
can't take FAX and modem calls at the same time.  Note that DV is not used
with this arrangement.  To do what you seem to describe, servicing both types
of calls at the same time, requires two comm boards and two different pieces
of software running.  They do not have to be DV aware; DV will keep them 
from interfering with each other by not letting each even know the other's
port exists.  At high baud rates, you'll want to be using a '386 or better.

Hope this information is useful.  Feel free to email if you have more
questions.  Like I said, I have a CCOM myself and like it.

I have an IBM PS/2 Model 95 running SCO Unix SVR3.2.4 that we use
as a LAN server for DOS workstations.  Communications are TCP/IP.
We will be adding Windows to the workstations soon, if that makes
any difference.

I would like to add FAX server functionality to this box, but the
only Unix FAX software I am familiar with -- Faximum -- assumes 
that the users are terminal connected, and I want to set the thing
up as a server -- workstations send it documents to go out, it
receives and routes incoming faxes to the appropriate workstation.
I am looking for unix fax software that I can configure to function
in this fashion.  Any ideas/actual experience would be appreciated.

Oh, and it'll also have to accept scanned input, and print to the
laser printer.  I'm not asking too much, am I?  :-)

"|/usr/local/lib/fax/faxmail"... unknown mailer error 1

Am I doing something stupid? It certainly runs the program.
I even modified the faxmail to echo the arguments it found and sure enough:

"|/usr/local/lib/fax/faxmail"... Connecting to baloo (prog)...

This was for h->phone, h->from, and h->return_path.

If you send the bignum with the fax then a person "bugging" you

Very easy. You build a struct with the information needed, i e files to send

Yes. No doubt about it. Fax modems are no competition, actually.
GammaFax boards beat fax modems on all sides.
If you want a comparison, tell me.

Actually you CAN use the GammaFax XP card with the API too. But you can't
use the realtime interface calls, but have to go via the queue-file. You will
probably do this anyway, so it isn't a big problem. GammaLink says that you
can't use the API with XP cards because you can't use ALL of the API.

The facts are that the fax protocol includes stuff that your mere mortal
1200 baud modem is not capable of.  The fax protocol uses a whole
different set of CCITT V. numbers (V.27, V.29) and 1200baud is not
really an option.

When a fax transmission starts, the two modems decide on the data speed
by going through a negotiation phase that determines the protocol and
speed to use.  This uses a synchronous, error checked mechanism that
works out what the highest error-free speed is available.

Then the faxes start data transfer in a completely different protocol,
that is half duplex and not error checked (usually).

Even if you get around some of the problems, most faxes have a low-speed
of 2400 baud.

What are your opinions of the fastest modem protocol for interactive
use during a zmodem transfer?

I want opinions on the fastest modem protocol for SLIP connections
when using "normal" dial-up phones lines.  Assume a moderate
amount of line noise.

And during a simple 'tip' or 'cu' data transfer?

How about large uucp transfers?

I hope your answers will focus on modem protocols as apposed to
modem manufacturers or particular transfer programs.

ISDN is (unfortunitely) not available where these modems are
being installed.

I will re-post results.

[ netfax is buggy ]

I've posted about this exact bug before.  That's what happens when I
use free software and don't have the time to debug it myself.

The authors are unresponsive.

I hope that one of the authors contacts me about a bug in one of the
programs that I distribute freely on the net just so I can ignore their
email.  (ha ha, only serious).
