It's safe with ISDN. However, the modem is probably still sitting behind
a device which fakes a phone line -- which makes this unsafe unless you
can monitor the ISDN line for incoming calls.

You really want either something which sits directly on ISDN and speaks
64 or 56 kBit/sec (if ISDN), or separate lines for dialin and dialout
(if POTS). Ask your PBX manufacturer or your telco. ;-)

I was not aware they were supplying HST with their v.32bis only smaller
footprint modems!  I know for a FACT that if you have the older, larger
HST, and even maybe the newer HST, that it lacks the v.32bis DSP.  I would
like to hear about this AT command.  I have the v.small DS, and have found
only one secret command: ATUSR.  Shows you info about it's designers. 
I've managed to get a copy of the ROMs in a file, and upon examining, I do
not see the commands directly in memory.  But I see alot of text that
might be part of an elaborate test the modem can carry out, but only with
a command I do not know.

[discussion of Digicom soft modem deleted]

I don't know why I'm defending AT&T, but here goes... :-)

The model which PC Magazine reviewed (March 17, 1992) was the Comsphere 3810.
This is one AT&T's high end modems.  It is better compared with the Digicom
9624E+.  It has 4 wire leased line capability, an LCD front panel, and other
high end features (like automatic upgrades through downloads over the phone
line).  The review gives a list price of $1595.  This was the only modem in
the review which "worked for us every time over every line and with every
other modem".

Here are some prices I wrote
down, though unfortunately I can't remember the name of the company:

	Comsphere 3810	$1195
	Comsphere 3820	 $995	no 4 wire
	Comsphere 3830	 $795	no lcd front, no 4 wire

It is possible that these are new list prices, given that the review is a
year old.  If anyone wants more info on AT&T modems, they should call
800-482-3333.  They can also send info on the AT&T Dataport series.

Another possible reason for the high cost is the high demand for flash eproms.
Not too long ago they were on allocation.


Now a couple of questions for you Wolfgang,

Can you please confirm that the Scout+ will not operate over 2 wire leased
lines.

Is the 9264LE+ FCC Class B approved?

Thanks,
Galen Seitz

There was just a thread about this last month in this group, if I recall.
To sum up:
If you use pulse dialing rather than tone you need to set the pulse
make/break ratio to match the country you are in.
The pattern for incoming ringing may confuse the modem, but of course
if your calling is all outbound who cares.
You will need an adapter cable or plug for each country.
Some countries say you can use only "approved" modems, but that is only
for protectionism and not electrical safety.  A modem that has US FCC
approval will be safe anywhere.

  There's no absolute security, you just start at a locked room with
armed guards, isolated power supply, magnetic shielding, and retinal
print ID of users entering the room. Then you work down the scale until
you get to something cost effective for your application.

  Callback makes it *harder* to get access to a system, not impossible.
It keeps the person who gets a number and password from getting in. It
means the cracker needs more info and expertise to get access. Rejecting
something because it's not perfect is not something I recommend, unless
you can get something better which is still cost effective. Doil-out

Another way around the call back problem would be to put the modems
behind an ACD (Automatic Call Distribution).  This is a little bit more
sophisticated than just a hunt group in that every incoming call goes to
the next available line in sequence.  It's virtually impossible to be
able to dial back in to the same modem just as it is about to dial out.

Ummmm, I agree this is a problem, but I don't think it has much to do with
Silent Answer.  Silent Answer is where the Supra picks up the phone (kinda)
when your answering machine does, and listens for Fax tones.  If it hears them,
it fully goes off-hook and into fax reception mode.  This should make most
answering machines stop (they assume that a human must have picked up, and
should shut themselves off).  I believe it also sends a few fake RINGs to the
Fax software, and then gives a fax connection message.

Serial port arbitration comes in when you've set +FAA=1, so that the modem
will answer as either a fax or a modem, and will return the appropriate code
depending on what connection was established.  At this point, it's quite
difficult for the program that currently controls the serial port to pass it
off to another program.

There's a demo copy of LineShare on sumex-aim.stanford.edu, which reportedly
will handle this for you (arbitrating who gets the call...).  I haven't had
a chance to try it out, only having one line untill I move to a new apartment.

I just got a ZyXEL U-1496E which for the most part I like, but I have had
one problem.  If I interrupt the computer during a transfer, preventing
it from taking the data in the modem's buffer, the buffer fills and the
modem drops DTR.  However, this only happens under certain circumstances.
9600/v42bis zmodem transfer do not have this problem.  When my computer is
interrupted, the modem gets the message and the other end stops sending.
14.4k zmodem transfers do not work.  Neither does sending strait ascii
at 9600/v42bis rapidly (ie, running yes)

Is this a correctable problem, and if so how do I correct it?

Hi Wolfgang,
 do you know how the software/the modem distinguishes between
 voice and fax ? Does the voice caller hear any carrier beeping ?
 Or does the software simply check for the fax calling tone ?

On the ZyXEL U-1496E (as on many external modems) there is a light called
HS.  On modems generally it lights up if you are at your highest speed.
On my ZyXEL U-1496E it lights up if I am at 9600, 14400, or 16800.

Nothing about the light tells you which of those three is the case.

I realize from your post that you cannot easily go into command mode 
because of the application you are running.  Too bad.  As I'm sure
you know, if only you could get a chance to see the "connect" message,
you would be able to get the answer.
Or if you could escape with +++ and then type ATO, you would again
get the connect message with the answer.

One of the ZyXELs has an LCD display.  Maybe it shows the data rate
on the display?  Does anybody know?  The user manual I have 
suggests that the U-1496 (with no letter at the end) is the one
with the LCD, and that the display shows both the DCE data rate 
and the phone-line data rate.

I have one, but would not recommend it to anyone.

The KERMIT problem has been worked around in the current MS-KERMIT patch file.

I have seen mentioned in this group the current card includes a daughter-board.
It is possible that this card fixes a lot of the firmware/Rockwell problems
with this modem.  The board is completely surface mount without any way
to upgrade the ROMS. 

The Gateway BBS is useless for locating patches or known problems with the
modem.  Support sucks.  The "technical" staff doesn't know a lot about
modems (BREAK? What's a break?  Why do you want to send one?).  

To their credit, Gateway <WILL> take the modem back, but they won't fix
the problems.  Save yourself the trouble.  Buy something else.

Therefore, the job defaults to the modem.

IMHO, a good modem should have the following option: If the remote system
disconnects, assume that DTR is low (which usually implies not answering the
phone) until DTR _really_ goes down, or until an AT command is sent.

This would mean that a panic'ed system would answer at most one phone call
per modem. That's not a perfect solution, but it's simple and it works.

Hi!

I have a modem and a PC. That's it. No cable, no documents, nothing.
I have access to ftp, so can get hold of shareware/PD. I can't afford 
anything expensive at the moment - probably can't even afford the phone
bill if I do get it working!

So what I would like to know, sorry if this should be in a FAQ, but
I can't find one...

Do you need to have the technical specs of a modem to use it - or
are they all pretty similar things stuck on the end of a serial port.
If so, will I have to find some kind of device driver particular to this
modem?

It has a 25 pin D socket on the back. Somebody told me to connect this
to the 9 pin serial socket on my PC - is this correct? Can someone 
give me a list of the pinouts so that I can make the cable up? (To make 
it will cost me about $2 ... to buy it, I have only seen it in one shop
and that was $15) Of course, I am not keen to buy a lead only to find out
that the modem does not work! (That's right, I don't even know if it works.)

So PLEASE PLEASE PLEASE, will some guru out there send me some advice?

Thanks
