Does anyone know offhand how to prevent windows xp/vista/7 from automatically searching all available com ports on startup for modems? Its an annoying feature at times.

    I did this once and couldn't access my 56k high speed AOL anymore :tongue:

    Why is it annoying? What problem is it causing?

    You might have to disable plug and play as a whole, you could try it temporarily to see if it solves the modem search issue.

    If the fax service is enabled that might be searching too.

    Or it could be you have a modem in your system with no driver installed and it is prompting for the driver? If that is the case you can just disable the hardware in device manager.

    The issue it causes is with end users. I have become tired of custom driver issues with modems, and have gone to ftdi converters and rs232 modems. Its a big improvement. However, windows always prompts to install drivers for these modems, which I don't want. I want to handle the modem completely through rs232, and don't want windows doing anything extra. Windows vista and 7 can do some real odd things with sound volume/mute per application and otherwise, and I have suspected there could be some relation with this.

    Another thing that can happen with xp media edition, is that it will hold open all available modems that have caller id and watch for incoming calls. You have to specifically disable this feature.

    Hmmm, it seems like you're a power user on the wrong OS lol... There's a bunch of stuff you could possibly do but keeping it really simple, something like this may go a long way - http://www.basta.com/Product.aspx?pid=13 (something like this, not reccomending this one specifically)
