    Hi everyone!

    I have a slight problem with my dial-up connection.

    I'm using a ZOOM modem model 2986 and Digiplus as provider.
    I'm connecting at 40,000bps instead at higher speed (115,200bps).

    Can anyone tell me how can I speed the connection using AT commands and what software to use to do that?

    Thanx! :)

    All up in your bidness
    When dealing with modems there are two different link speeds that the AT command set recognizes: the speed of the link from the computer to the modem, and the speed of the link from the modem to your ISP's modem. Because it's physically impossible for a modem to connect to another modem over the telephone line at anything higher than 56K, the 115,200bps figure has to be the speed of the link from the modem to the computer - not the speed of the USB connection (obvously that's faster) but the speed of whatever layer of legacy protocol junk the modem uses.

    In other words your modem never connected to the internet at 115,200 bps. If it connects at only 40,000 bps now, it probably always did, but you never saw that it did because your modem init string told the modem to report its modem-to-computer link speed instead of modem-to-modem link speed. Probably it's better now, because now you know the REAL speed the modem is connecting to the internet at.
