 ===========================================

Doug -

I just tested one of Cleo's boards (3270 SNA Remote Linkix) on 
Microport SVR4.0.4.1 - it worked fine using a UDS v.32 modem. We
had no problem talking to a mainframe.  I believe the UDS modem
has a v.32 SDLC synchronous mode.  I tried using our Telebit T-2500, but
had no success in talking to the mainframe.  I could make a connection
using the async->synch v.32 mode (dials in asynch, then goes synch
when connected) but couldn't get it to talk to the mainframe.  The
SDLC protocol might work if you had another T-2500 on the other
end - the T-2500 only has PEP mode SDLC !

I think almost any operating system will work - the Cleo board takes
care of the synchronous communications.  I think UDS modems are fairly
popular the with big iron crowd.

I have a modem (Digicom Scout Plus) with all the trimmings (V.32bis, V.42,
V.42bis, ...) too and I still get some errors during Zmodem downloads.  

Even on pure local connections I regularly get CRC errors, timeouts 
or bad subpacket errors every other second so that the data rate on 
downloads seldom climbs over 900 cps at 14400 EC, often 700..800 cps. 
The line dont seem noisy, signal strength shows -27...-24 dBm and 
signal quality shows mostly 7 or 6 on a scale of 0...7 (nice feature 
on the Scout Plus). 

That means most file transfers need about twice the time to download, 
a factor of 3 is no great improvement over my earlier 2400 (no EC) modem 
when I hoped for a 6 fold improvement. 

Or can that be a weakness of my datacom software (Telix 3.12)?

Or the missing 16550? (DTE rate 57600 or 38400, 12 MHz Compaq 286). 

Any ideas, what could be wrong?

Proctor & Associates makes a variety of exclusion modules, including
ones that divide the line into two groups (one feeding the modem, the
other feeding telephone extensions) and another kind that is just
plugged in series with each phone that you want your modem to be protected
from.

They also make a neat security device for modems, the 46300 Secured

Article-I.D.: vax1.1992Sep3.234212.1
Organization: University of Missouri - Kansas City

I just got a Twincom 14.4kbps internal Fax/Data modem.  My problem is that I
keep getting NO CARRIER while I am working on my school's VAX at 9600bps.  It
connects fine and works at what must be 9600bps (boy that's much faster than
my old 2400!).  I am using Procomm Plus 2.01 under DOS 5.0.  The software is
set for 57600bps connections, but if I issue the MODE command under DOS for 
19200 (MODE COM2:19) DOS claims that my system doesn't support that speed.
I now have it configured for 9600bps and seem to have no problems yet...

Any ideas what my problem is?

Thanks for any and all help, and thanks for all of the help so far.

I know it can be done, but I can't find it anywhere in my FM...

I need to munge up my modem settings to call one machine, and I need to
have the modem returned to its normal state at the conclusion of that
call so it can deal properly with incoming calls.

I'm using a Zyxel 1496, and surprisingly I don't see anything in the
manual about an option to force a reset after DTR drops.


Lacking that, I've heard that HDB uucp can issue a command string to the
modem on hangup, but my docs make no mention of how.

Can someone enlighten me?

Thanks...

I recI recently tested a few different fax programs. All of them were 
ently experimented with several different fax programs. All of
them for IBM PC compatibles and DOS. BitFax has the most drivers for
different printers and video cards, but its interface is clumsy. Also,
it did not always work with the faxmodem I used (a Digicom Scout+).

The next program I tried was Smith Microsoftware's Quicklink II. I did
not test it extensively, but from what I saw it appears to be a bit
clumsy, too. The fax connections I tried were a bit erratic, too. I
most likley need to do some more tests to figure out what is going on.
Finally I tested DosFax, which is now included with Scout+ modems which
I sell along with WinFax. It worked on all connections I tried, among
them faxing from California to Thailand, to Germany, across town to a
variety of fax machines known to be difficult. The downside is that
DosFax is rather slow in executing the commands. The interface is easy
and intuitive, though. I am not sure that upgrading to DosFax Pro does
much good. I prefer small simple programs without many features. You
can fax directly from within DOS applications by printing to 'capture'
and then pressing CNTRL SHIFT F (for faxing). Type in the name to whom
you want to fax and if its in the phonebook, off goes the fax. Delrina
tech support is supposed to be available, but I have given up on them.
The lines are too busy. I dont know how good the manual is, I did not
read it.

I think there is still an opportunity for a shareware fax program,
which does everything right: intuitive, fast even on slow machines and
working reliably.

Hi, all.
I have a Zoom "Turbo" V.42bis, V.32 modem.  It has a 12000bps

Our school just upgraded to Digicom 9624LR+ V.32bis modems,
but my Zoom still connects at 9600.  Anybody have any 
suggestions?  I know this has been brought up before.  Seems
like somebody mentioned a change that could be made at
the other end to let it recognize the Zoom's 12000bps mode.

Thanks for any help you can provide...

Does anybody know of any products capable of BFT (T.434)?
If not, is there any possibility of beta testing and/or
compatibility testing? As ASN.1 coding is not such easy there
is a chance for incompatibilities without testing among different
vendors.

Anyone implementing BFT should contact me by e-mail so that
we can arrange testing and discuss interpretation of T.434.

BFT will be a great thing for many users. Let's try to bring it
to the market as soon as possible!

I've got a problem with my modem.  The modem is a Nuvo 14,400 which uses the

an unexpected disconnection, the modem does not hang up and I can't reconnect.
In fact, when I go to my communication software (ProComm Plus and/or PCPlus

Date: Mon, 14 Sep 1992 05:25:57 GMT

Three times within the last few months, my computer has `frozen-
solid' after I have left my word-processor unattended.  Having
followed the discussion for the last week or two in this group, I
am beginning to suspect that the problem may be that my modem is
not hanging up correctly.  I twigged to this possibility tonight
when the phone rang while I was using the word-processor a half-
hour after I had exited my communications program: I answered the
call, and when - five minutes later - I tried typing at the
keyboard, the computer was frozen.

I am using Qmodem 4.31 and a Patriot 2400i 2400 baud internal
modem.  (I always exit from QMODEM using the Y option [drop DTR]
and never the x option [leave DTR up].)

What should I be looking for?  Should I fetch a utility from,
e.g. SIMTEL20, to display on-screen a mock set of modem LED
lights (to be run after exiting QMODEM)?  If so, what utility
should I use and what light's being on would indicate that the
modem has not disconnected properly?  And if the modem has not
disconnected properly, how do I force it to?

Or, instead, after exiting QMODEM, should I run MicroSoft's
diagnostic program MSD to report on the interrupt status, etc.?
If so, again, what should I be looking for?  And how should I
correct it?

Or, should I be doing something else?  (I could of course do a
cold reboot, but that's a bit drastic, especially since I use the
modem a dozen or more times a day.)

Please, any help would be most welcome.  Thanks.

Specifically, I am trying to determine the importance of supporting
break (and preserving the length of the break) in various protocols
that carry async data across different environments.

Do you use break?  What for?  How important is it to you? Do you
know how long a break needs to be in your application for it to be

breaks were intercepted or not transferred, you could still make 
efficient use of the application?

This is true except that there is a fair amount of work for the 
modem to do to support the T.30 error correction mode. Also you
need quite a lot more RAM (64kb?). So most current fax modems 
don't do it. So they don't do BFT.
