Sony Notebook Built-in Modem

Ray,

In most cases, where a V.90 modem is involved, the V.90 protocol is attempted
first, if it is properly setup.  Make sure you're using the correct INF file
and review your manual in order to make sure you haven't inadvertantly disabled
the V.90 protocol with an errant additional command.

Sincerely,
Tester98

Ray,

I can see that this is becoming a considerable irritation, but stick with me
and don't despair.  If "I" am ultimately unable to help you, I'm sure someone
in this newsgroup can.

Using the information you gave in the original post, I drew my "conclusions",
such as they were.  Irrespective of the possibility of getting a faster speed
from another computer while on the same phone line, the conclusion was that it
wasn't a "modem" problem.  That doesn't exclude the possibility that in both
cases, concerning the original computer, you may have used a similar setup
which limits the best possible connection achievable by "that" computer, no
matter what modem is in use on it.  In other words, you may have implimented a
maximum port speed which is limiting the connection and operation.  But, the
original post didn't seem to lead in that direction and I've subsequently not
gone in that direction, "yet".  If you find the following to be non productive,
we will proceed in another direction as appears to be warranted.

That notwithstanding, assuming the INIT string you presented is correct for
your modem, I think you're missunderstanding its proper implimentation.  The
most limiting factor in modem communications is dictated by the phone lines.
If the line conditions don't permit a specific speed, then it is useless to
expect the modem to be "forced" into operating at that speed, which the phone
lines will not allow.  With this in mind, you should set the modem (high end)
at slightly more (one increment) than the highest speed you appear to be
getting, and set the lowest speed at that which is the least acceptable.
Assuming that the "12" means to use V.90 the protocol and "1" means to enable
automode, you might try this:

                +ms=12,1,28800,42000

Also, don't rely on the "Connect" speed that may be indicated when you first
log online.  It is better to go into a terminal program immediately after your
online session and type "ATi6" (without the quotes) in command mode, in order
to display the parameters of that last session.  You should see a line
displaying something similar to 38000/28800, where your (actual maximum)
download speed was 38000 and the (actual maximum) upload speed was 28800.  You
should also see a line which indicates the protocol implemented.  If ATi6
doesn't display this info, then try ATi5 or ATi7.  If you have an indication
that as much as a speed of 40000 was attatined, then you might incrementally
raise the upper speed and review the subsequent data in the same manner.  Keep
in mind, that if you have a download speed greater than 33600, then you have
one of the 56K protocols which was accepted by both ends of the communication.

Please keep in mind that almost everyone on the internet uses a different setup
in one a

Ok, sounds good.

                ... <deleted>...

Have you tried this?... +ms=12,1,42000

                ... <deleted>...

That's good.  At least we won't find that we're taking readings from different
sources.  Since you do check &V1, would you mind posting the next one, along
with the &V command results?  I will assume that `all' issues previously
mentioned have continued, unless otherwise specified.

Have you gone one step further and tried the above mentioned "limited" INIT
string I suggested?  Although I do have a 56Kflex modem on another port of my
computer, I only use it on very rare ocassions and therefore, am no expert on
the Rockwell/Lucent chips.  As a matter of fact, I've been dissappointed in the
fact that I can only get from 38000 to 44000 connects with it.  Since I already
have the V.90 ability in my main modem and I would lose the 56Kflex if I
flashed the other one, I've refrained from changing it.  

But, I did notice something peculiar about my main modem which is a USRobotics.
 I wasn't able to "restrict" the range of its operation as is indicated in the
manual, much the same as you mentioned in a prior post.  Last night, I
refrained from specifying the upper limit and only designated the lower limit,
which is not a "recommended" setup by USR.  It worked in giving me a V.90
connection of 50666/31200 where before, I had only been able to achieve a
connection of 41333/26400.  It consequently occurred to me that a similar
application of the proper commands in your case may have some benefitial
effect, also.

I'm glad to hear it.  We may whip this thing, yet.

That particular INIT string was just a guess, considering something I
experienced with one of my modems.  

Your "Line Quality" leaves something to be desired, judging from the respective
line.  Also, the "RBS" line indicates far too much having to be compensated for
in the way of distortion of the signal.  You can see the results of it in the
"Rate Drop" line, which is tremendously high as well.  I've not seen it
mentioned in this newsgroup, but there is always the possibility that there is
some device introducing noise on the line.  If you can periodically hear noise
when you are on the telephone, it should be corrected.

With the V.90 protocol, you should hear two very distinct `pings' about a half
second apart, near the later part of the negotiation.  If your modem isn't
attempting to implement the V.90 protocol, one of these three things is most
likely:

1) You are experiencing line noise problems that prevent the protocol's use.
       Line noise appears to be a possible hinderance.
2) Your modem isn't attempting V.90 at all.
       a. Are you sure you have a V.90 capable modem?
       b. Do you know which register indicates the protocol?
3) The POP doesn't support V.90, yet.

That's about it for now,
