There's no way to do this with full-duplex modems (that transmit 
their carriers continuously); they will always interfere with each 
other.

What you could do is put the two terminals on some kind of sharing 
device on the EIA-232 side of a SINGLE modem.  But that would mean 
running an EIA-232 cable from one to the other, which might not be 
possible within the building.

The other suggestion would be to figure out some way to bump the 
other station off the line, if you find you gone home and left the 
office computer connected, or vice-versa.  I find that oftentime 
simply going off-hook with a telephone and mashing a few touch-tones 
will confuse one modem or the other enough to cause them to think 
they've lost carrier and hang up.  Another alternative would be get 
Call Waiting on the modem phone line, and set your S10 register a 
little bit lower; then, to cause a disconnect, just call the modem 
line from another phone, which will cause a Call Waiting beep and 
thus a disconnection.

Another thing you could do is set up some kind of "inactivity timer" 
so that if the link sits unused for more than a few minutes that it 
will be automatically disconnected.  This is a feature of many 
modems, but you could also set it up on the host side or in your PC 
software (some packages).  I know, for example, that our Vax here 
will log you off if you don't type anything for several minutes (it 
warns you first).

But, of course, the easiest thing (and the safest, from a security 
point of view) is to just always remember to log off whenever you 
leave your office or home.

I will be moving to Paris this October, and want to buy
a high speed modem to dial back into networks here in the
US, and wonder what features I should pay attention to
in a modem that can handle the lines from France (and later
Germany) to the US.

My brother just tried to call some modems in the US with
his new Zyxel from Germany, and despite that the lines
sound pretty good acoustically, the effective speed he got
was more like 300 baud.
What's the problem there?
Does anyone have experience and advise? Thanks!

But there is no "modem tax."  Compuserve is yelling because they don't

I've recently called Paradyne about their modems.  This is what
I've been able to find out.

They currently have 3 models, the Comsphere 3810, 3820 and the 3830.
They all have V.32bis, V.42 and V.42bis (including downward compati-
bility with V.32, V.22bis, V.22, MNP4 and MNP5).  They negotiate 
downward and upward (in V.32bis), and was found the most reliable
modem by PC Mag.
 
The 3810 is the most expensive, at $1195 retail.  It also has the most
features, including 2 or 4 line leased line and ATT network protocol
built in.  It also has flash ROM, so ROM upgrades can be done over the
phone.    

The 3820 is a dial only modem, at $995 retail. It also has flash ROM,
like the 3010.  

The 3830 is also a dial only modem, and at $795 retail, is also
the cheapest of the three.  It's virtually identical with the 3820, 
but instead of flash ROM, it has EPROMS, so for any ROM upgrade, you
must send the unit back to ATT.
  
I don't currently have a list of vendors for the ATT modems, so I
can`t provide you with one.  
  
Hope this helps.  Also, you can reach ATT Paradyne at (800)482-3333.

Hi there!

    I am looking to buy an external V32bis fax/modem.

I got a great price for a USR sportster (409$CDN).

The thing is... the salescritter told me that if I buy one
for my PC, it won't work on a mac.

I suppose (he didn't tell me this- he didn't seem to know that much)
that it's because of the difference between the two type of serial ports
(422 on the mac and RS232 on PCs).

I currently own a PC but I might eventually want to buy (in 1,2,3??? years)
something else (Mac, Next, Indigo??). The thing is, Mac and Indigo have only
RS 422??

That is the reason I initially wanted to buy an external modem: so I
wouldn't have to buy a new one when I sell my computer!

Is this a problem? 
Are there any trivial/passive/cheap converters for RS232<->RS422???
Are there any modems that take both???

Thanks

Sebastien

DAK sells these modules that you plug your phone into that keep other
phones from being able to pick up the line.  Theyre like $6-7 a piece,
but you need one for each phone, including the modem line.

that's about what you'd expect.  somewhere between 1650 and 1700 cps.

don't rely on that.  try downloading plain text files.  granted, these
can be hard to find other than, perhaps, file listings for the BBS.

also, keep in mind that if the board has their serial port set at 19.2,
you won't see much difference, because their serial port speed is the
bottleneck.

and, as far as the 4:1 compression, don't count on it....  when I grab
text files off of a BBS (V.32bis/V.42/V.42bis, serial port set at
38.4 on both ends, and a 16550AFN in both serial cards), I normally
see around 2550 cps to 2800 cps.

if you see V.42/V.42bis (or something along those lines....some modems

message, you know it's there.  if the other side isn't using V.42bis,
neither are you.....  :-)

John;

Since you have v.42, you should use a speed higher than the modems
will be talking to each other so you can take advantage of the 
compression they are providing.  Depending on what kind of information
is flowing through the link, the modems are capable of something like
a 4:1 compression allowing you to see effective throughput rates higher
than 14,400.  So, run your serial port at say, 19,200 and you'll get
somewhere between 14,400 and 19,200 bps.  (This is only true when you're
talking to another modem that supports v.42.)

Since a v32bis modem supports data compression and can send data to the
computer at higher than the connect rate, you will want to set your baud rate
at least at 19200 if not higher. In order for this to work you will also have
to enable rts/cts and have a cable with the handshaking lines connected (which
is most of them).

I've tried the V.32bis and seem to be getting significantly better

22kb modulation, while V.32bis is only 14.4kb. Is the fact that
PEP is half-duplex hurting UUCP that badly?

Indeed, that is the case.  As per a note I received from
Donald.Stoye@eng.sun.com (Donald Stoye who questioned PPI and got the
following response:

   I fear that there is some misunderstanding about the &T19 command.
   This is NOT a command which can be used from the command line and
   given directly to the modem by manually typing. It is a time
   sensitive situation and MUST have software support. The only
   communications program which currently supports this test is
   SmartCom Exec from Hayes. This command requires software support
   and it works properly when that software support is available.

			   and

   As I noted to you in a prior reply the "AT&T19 error" is not an
   error at all. The &T19 test requires software support. This is not
   clear from the documentation, but that is the case. It cannot be
   used from the command line manually.

However, there have been reports as well that say PPI is aware of this

We are having problems getting a 'SMART ONE traveler 9624FP' fax modem to
operate.
We have set it up for CCITT V.22 but it will not connect, we keep getting 
error message 'No dialtone'. We have tried it at 300 and 2400 baud but no
success. We have tried it on an external line as well as through the local
exchange.
