Dialup baud rate indication

I am confused.
I am using XP Pro and IE6.
It seems that there are two options for how my ISP connection baud rate is
displayed.
One gives me the actual connection speed, usually between 47KB and 43KB.
The other gives me about 112KB which I gather refers to the connection from
Windows to the modem.
How can I change the latter to the former?
Thanks
Brian Tozer

it depends on the type of modem you have... usually you have to add an
init string to get it to show the right one.

from memory, the old rockwells used to need w2 added in there, and it
showed it right.

Basically these are DTE and DCE speeds. Look in your modem's
documentation for the command strings that need to be sent to the modem
to change the data. It is basically what is returned by the modem in a
response (if you turn on the modem logs you'll see the numbers come up in
the log files)

Thanks Patrick and other replyer.
Both very helpfull.
With hindsight I think I worded my query poorly.
I have two different PCs, both running XP Pro, and each giving the different
speeds that I referred to.
Both using the same type of modem.
I will look into the respective modem info in their log files etc., hoping
to spot something.
B.

That would just be the initial connect speed reported by the modem in the
task bar, which is the result of the init string.
The data transfer reported by the applications should still be the same

as in one give DCE and the other DTE?

probably different driver revisions or something.

There is no practical reason for knowing the actual connect speed of the
modem at dial time, as this speed will vary over the course of the
connection session dependant on line conditions (noise and so on). A lot of
modems will connect at a high speed and slow down to lower speeds pretty
early on in the session.

At best the only reason for knowing it is to gauge your line conditions;
little good this will do you with Telecom however, as they will insist on
their own tests.

A more reliable estimate of your line speed is to take the average transfer
rate for downloading files over a period of some days from a variety of
sites. Or perhaps from your own ISP's FTP server to eliminate slow servers
elsewhere on the net.

If you really must have the modem to isp initial connection speed, I think
you will need to look at the drivers for the modem. You can also do the
same with certain init strings in the modem properties advanced settings.
Make sure you turn on hardware flow control and error correction while you
are at it.

What will be reported is the response from the modem to a specific
command string.

Applications that do data transfer, from my experience, report an actual
rate that they have measured.

Speed changes tend to be downward only.If your ending speed is
consistantly much lower than start speed consider limiting the start
speed. Every speed change is an opportunity for dropping the connection.

We sent W2 which in the command set for this Rockwell chipset modem is
"Error correction call progress not reported. Connect XXXX message
reports DCE speed"

from
07-20-2004 19:11:28.72 - Recv: <cr><lf>CONNECT 33600/ARQ<cr><lf>

This is the reported connection speed.
