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

    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.

    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.

    Brian

    115200 is one of the 'standard' Serial connect speeds i.e. 75, 150,
    300...9600...14400....etc.

    I have usually found when the Serial speed is being reported and not the
    modem / modem connect speed that the wrong or incomplete drivers have been
    installed.

    Windows 'generic' drivers will allow the modem to work quite adequately,
    typically though you get the serial speed not the modem/modem speed
    reported.

    The modem command 'ATW2' usually causes the modem/modem speed to be shown,
    but like all these things 'your mileage may vary'

    I would reinstall the 'correct' drivers for the modem / Operating system
    after removing the old ones first.

    Cheers
    Paul.

    I think W2 is for Rockwell chipsets, may not work for all modems.

    The modem manual should show the correct code to use.
