  • COM Ports on XP

    I'm trying to get a modem working with XP on a rebuilt PC (ASUS
    A7V8X-X).

    The machine has a swappable disks and the 'old' disk has 98se
    installed and on that the external 'standard' (i.e. not soft) modem
    work fine.

    A new disk has XP newly installed and the modem will not connect to
    the ISP. It is using XP's default 'standard' modem driver so no HCL
    issues. The error reports that the COM port is mis-configured or
    already in use. I've double and triple checked the port settings and
    they seem fine. Numerous re-installs of the drivers and a re-install
    of XP later im here :)

    Under XP the modem shows some communication is going on soon after
    booting, even before the system tray icons are shown. About once a
    second the RD/SD start flashing under XP. They dont on the working
    98se.

    I've settled on the COM 1 port being in use by something. I halted
    all the processes I can and only system process are left.

    There is no additional software installed that 'should' be using the
    COM port that I know about, no voice-ware, fax-ware, etc.

    The machine is a friends and has a few legit games installed but
    nothing running. I've run Add-Aware and ASUS PC-cillin (ASUS virus
    s/w), it also has ASUS hardware probe, but the problems occurs with
    these stopped under XP.

    Does anybody have any clues ?

    Is there anyway under XP to find out what is using the COM ports ?

    thanks in advance
