Speed up your Modem
Even if your modem is apparently working well, the baud rate of your COM Port might not allow you to reach top-speed. To improve your port's speed:
1. Click Start > Settings > Control Panel > System.
2. Click the Device Manager tab, and click on the "+" sign next to Ports (COM & LPT).
3. Select the port your modem uses, click Properties, then click the Port Settings tab and set the Bits per second to 115200 bps. That way you won't have a sort of filter on the Port.
