That's not necessarily true.  It is not uncommon for a sw package for
UNIX to cost $625 *per node*.  It is usuall more to get a site license
or a floating license for 'n' machines or users.

I 

I use the 3261Fast, and I can say its a super nice modem! Though they don't
come cheap at all...$3695.00 for two. They run in leased or dial lines. DTE
rates from 300-115,200 bps link rates:

  Cfast 24.0 - 21.6 - 19.2 - 16.8 - 14.4 -12.0 - and 9.6 kbps
  V.32 bis 14.4 - 12.0 - 9.6 - 7.2 - and 4.8 kbps
  V.32  9.6 - 7.2 - and 4.8 kbps
  V.22  2.4 and 1.2 kbps

One neat feature I like it it can be programmed from the from front panel
or use the AT command set. You get the heavy duty RS232 cables with it and
a special RJ-11/RJ45 cable to connect it with. It also has passwords to
prevent it from being re-programmed, call-back,Network Control Address,
and of course all the other 'goodies' we have come to expect in a good modem.

Its a real speed demon!!  I won't waste other readers time but if you still
need more information, let me know and I'll email you. BTW, I don't work
for or have any relationship with Motorola.

Reply-To: monty@info.win.tue.nl

Hi,

I own a Zoom v.32bis fax-modem. Whenever I make an ordinary
modem-connection everything works out. But when I make a
fax-connection I can hear during the wait for the other device
to pick up a intermitting high tone, besides the normal tone.
Normally this doesn't influence my connection, but when
faxing to abroad I can't make a connection: the other fax picks
up the hook but my modem doesn't recognize it doing so.

Does anyone have an answer?

Merry xmas and happy newyear,

I have a modem ZyXEL U-1496+,LCD which is used for a leased line,
4 wire (and is configured for ZyX-16800 bps asynchro).
The thing is the line sometimes breaks down and subsequently the
modem tries to handshake and then turns itself into the wait mode.
As the modem is placed in the next building I have to go there and
recover the connection manually. My modem is configured as origin.
Is there any way how to configure the modem for trying to reconnect
instead of staying in the wait mode? Thanks in advance.

I am working on a similar problem.Yet,I have found some sources for doing the
fax compression and a very old fax package for SGI systems :
The PbmPlus package  : comtains some stuff to generate fax 1D-compressed
		       files
The Tiff library     : Also source for 2D-encoding; very puzzeling
I don't have the sitemanes ready, but you can ftp these packages from
a variety of sites.

From sgi.com : the "Flexfax" package. Contains modem stuff for Class 1&2
	       modems.


But i still have a problem : My modem uses the "Sierra sendfax chipset"
but i have no documentation on how to use it for sending a fax.
Which commands do i have to use, how can I stuff  a fax-compressed file
into my modem so the fax device on the other side receives it ?

regards,

To the best of my knowledge, there is a $15 shipping/handling charge for
return repairs on the PM14400FXSA (the one I have), but the card does say
that it has to be sent insured mail, so that runs it up a little bit more.
Of course, I paid $400 for that toy, so $15 is (relatively) cheap. :)

Yes, the 'P' stands for 'Plus'

My E+ reports: U1496E V 5.04f P

And this is definitely and E+, it does have CELP compression...

Yes, well... my ROMs are also 1.15m's, and while this has helped some, it
hasn't fixed the problem entirely... just made it less annoying.

They're middle-aged T2500's with the latest ROM upgrades; our site

Actually, the only problem I had with the Zoom was the fact that it would
incorrectly accept one of the PEP hunt sequence tones as 2400 bps 
carrier.  Since these tones are interspersed with silence, the Zoom then
got confused, thinking the distant modem had dropped carrier on it.  
Weak!  I got around the problem by tacking a ';' to the dial sequence, 
waiting 30 seconds or so, and then going back online.  Klugey, but it 
worked.  Later on I discovered that Telebit T2500's can be programmed to 
put the PEP sequence after the CCITT hunt sequence, which would have 
fixed this problem in the first place.

In any case, the Zoom 2400 v.42bis was far more reliable (with that 
kluge in place) than the 4800 bps v.32 fallback modulation I am forced to 
use with my PPI.  I can use 2400 on the PPI quite reliably, though.  
C'est l'vie.

The only Telebit modems with V.32 are the T1500, the T1600, the T2500,
the T3000, and the WorldBlazer.  The T1000, TrailBlazer+, and T2000 do

Ah.  I thought you were saying that you had tried calling the Telebit
both with the ZyXEL and the Multitech and gotten 2400/MNP4 connections
both times.  In this case, I'd suggest that you look at the registers
and what-not on the ZyXEL to ensure that you haven't told it to only
connect at 2400 or something like that.  As I don't have a ZyXEL, I'm
afraid I can't be any more specific than that.

A somewhat administrative question:

As a reply to an inquiry (not an order) about their IMPALA 24/96

 [ ditto ]

Since this is the second time I hear of such behaviour regarding modem
sales from the United States to Italy, I'd like to know more about it,
especially on which side of the Atlantic Sea the problem is.  Which is
the "government" Omron is talking of ? Are there Italian regulations
I'm not aware of that forbid import of telecommunication goods ?
Is this an US policy regarding high-tech stuff ?

I will be grateful to anyone who can (and will :-) supply information,
maybe Omron could explain more but I couldn't find an E-Mail address
for them, at least not in the States...

I'm a bit upset because I can't get my ZyXEL to work.
I bought it a month ago and have since been trying to just dial

Sounds like a problem with the phone line, but I tried it at several

Probably something's not set up properly, but I tried almost

told me was that the ZyXEL is ok and the NO DIALTONE message is
correct!(?)

I believe that there's no real problem involved and I would be

Could you perhaps post the information you get when you send AT&V to the
modem?  I suspect your problem is that the S0 register happens to be
non-zero.  To keep the machine from answering, set S0 to zero.

Hi yall,

  I hope this the right group for such questions ...

+------------------
  Are there any utilities around that will let me record and
play back activity on a serial line being monitored ? The playback
must be consistent with respect to timing also.
+------------------

  I wish to record one entire interaction of an application that uses
async lines (running perhaps some protocol sometimes, but always async)
and play it back over and over again for each demo.

  I am looking for a program that will use only one com port on
the MonitoringPC, tap the Rx line from the PC-being-monitored and
record all key strokes *with* timing information.

  Additionally if it can support another com port and also record
the outgoing traffic from the PC-being-monitored, that'll be a
bonus. 

   Nothing like it, if during play back, it can wait for the char
sequence that the PC-being-monitored sent out originally to come
out the PC-being-fooled, and send to it whatever came from the modem
using what it tapped as a chat-script of sorts.

All tips and pointers sincerely appreciated, even if it can do only
a part of all the above!

Thanx in advance.
