V.32bis modems will fall back to V.32.  I'm not sure if this is a
_requirement_ in the spec, but they'd be stupid not to do it, and I
have never seen a V.32bis modem that wouldn't do it.

This is terrible.  Using a ZyXEL 1496E I get over 1600 cps while having
multiple login sessions over a single serial line, through a gateway,
into a heavily used UNIX server at school (I'm reading news and
other stuff in my other login windows simultaneously), and get over 1700

Another similar situation here, also... My system did communicate with the
Intel 14.4EX, until an electrical storm FRIED mine too.  I am in the process
of getting warranty work/replacement, and have had NO problems with tech
support or service.  I have actually been impressed with the product and 
service, and as far as installation - couldn't have been simpler.

By the way, if anyone else out there has one of the Intel 14.4EX's, please
tell me your ideas on a good initialization string for the modem..  I am using
default settings from TELIX ver 3.15, and would like to hear some opinions
on initialization strings..

It's been a while, but I last look at (had a couple actually) the Courier HST
modems.  I was rather dissatisfied with them.  I found the Telebit Trailblazer
Plus modems much more reliable.  I'm all for speed (otherwise I wouldn't be
looking at these modems) but I also want something I can really rely on.
Maybe USR has improved things but the quality and features on the HST did
not impress me.

I'm getting some vibes from this.  This phrase has significant negative

there more particular reasons for this, or is the 10-15% throughput and
more money significant motivators?!

Organization: ka2qhd - Ocean NJ

I just purchased a new USR Dual Standard 14.4 with v.32bis/v.42bis ans ASL.
This is the external model with the voice/data switch on the front panel.
My question:
Could someone on the net who has the same modem confirm or deny I have a
problem.  I noticed immediately after hooking up the modem that when it
goes off hook I get I high pitch tone (which is audible above the dial
tone) and its volume is constant independent of the volume control.  If I
just issue the ATO command it can be clearly heard.  I called USR right
away and was told by a support person that they never heard of this problem
and he issued me an RMA#.  After waiting 20 days for the modem to be
repaired it arrived the other day with a repair form from USR just saying
that it was a pleasure to serve me.  No findings, and worse off they never
fixed the problem.  I would venture to say that the tone is around 2Khz.
The tone is very annoying and never experienced it with the HST 14.4 I
external I used to own but sold in order to get the Dual.  
Your feedback is appreciated.

 Hi Folks:
  I have a problem using tip on my SPARC ELC with a Telebit T2500
modem. When I *bring* files over from the remote site the transfer
is quite fast. While the transfer is being done tip displays the
number of lines trasnsfred till now. The speed is something like
20 lines (with >= 70 chars in a line)  in a second.
 However when I *put* files (using the ~p or ~>) command the 
transfer is painfully slow. tip also does not display lines but the
number of *bytes* transfered till now (every 100 bytes). The speed
now is something like 80 bytes in a second.
 Can anybody explain why this happens? And is there any way to fix it?
Is there some environment variable that I need to send?

  Your software sends the 8 bit byte ("octet") from memory to the UART
chip.  The UART adds a start bit and stop bit as it transforms the
octet to serial format.  The serialized bits, all 10 of them, travel to
the modem.  If running MNP4 or V.42 the modem removes the start and
stop bits to recover the original octet, applies MNP5 or V.42bis
compression if compression is active, then sends the (possibly
transformed bits) down the communictions line.  In the absence of error
correction or compression your local modem simply transfers all 10 bits
to the remote modem.

  You apparently assumed the data path between your computer and the
serial device, i.e., your modem, transferred only 8 bits per character. 
You also assumed a modem without error correction (MNP or V.42)
transferred 8 bits per character.  This assumption is incorrect.

  So, 14,400 bits per second on the telephone line translates to 1,440
characters per second out the serial port in the absence of error
correction.  With MNP4 or V.42 the start and stop bits are not sent
down the phone line, resulting in 14,400 * (10/8) or 18,000 bits per
second, which translates to 1,800 characters per second at your
computer's serial port.

  Technically the modems avoid transferring the
start and stop bits by switching from asynchronous to synchronous
modulation, if they both agree to do so.  Async data transfer uses the
start and stop bits to figure out the character boundaries, while sync
relies on the bits arriving regularly enough to use a clock to figure
out the character boundaries.

the V(dot)(something) numbers are references to CITT standards for
communications, but don't get confused by the fact since they all begin
with V(dot), that they are all related.

V.22bis specification describes a modulation scheme that sends 2400 bits
per second.

V.42 is a specification of a protocol (like ZMODEM is a protocol) to
provide error correction to a data stream.

V.42bis is a enhancement to v.42 that allows the data stream to be
compressed (like PKZIP is compression) as well as being corrected for
transmision errors.

So a v.42bis modem connection is analogous to you running your data thru
PKZIP for compression, then ZMODEM for error correction.

You can also say that V.42 is analgous to MNP levels 1-4 and V.42bis is
analogous to MNP Level 5.

If you get a 2400 BPS modem, it will almost definitely be a V.22bis modem.
It may have v.42bis as well, which means that compression might give you
speeds approaching 9600 BPS.  But both modems in the connection must 
support v42bis or you can't use compression.

Oh, did I forget to say that Supra included a free screwdriver with the

I'm not presently using their modem on a BBS and the "Fun in the sun..."
thing was open to everyone who bought Supra peripherals this summer, but I

	What I really need to do is get Vistacom too dial out through this 
internal modem.  But when I set the modem port to COM3, Vistacom still does 
not recognize that there is modem there.  How do I get Vistacom to recognize
the modem??? Is there dome DOS command or driver needed, or some DIP switches
set??   HELP!!!

	(note: when I attach a modem to COM1, everything works fine.  But I
NEED to use the 9600 interal through Vistacom though)
