VPC Serial Port Access -was it changed like the parallel port in SP1?

    The reason I ask that I have an old Microsoft 900Mhz
    phone that needs to run under 95 due to the version of
    Outlook Express required to work correctly, but in a pre-
    sp1, the phone would install, but would never be
    accessible by the phone software itself, and the phone is
    mostly run by the computer itself (at least all the
    truely useful bells and whistles)

    So I'm wondering if the serial port access wasn't
    exclusive in the same way that the parallel port access
    wasn't exclusive, causing the phone or the driver itself
    to choke on the serial port somehow.

    Ben, Microsoft must have a few MP900s lurking about
    somewhere for testing, if you get a chance, you might
    mention to someone on the dev team to try it out as an
    example of something that doesn't work with the serial
    port code correctly (persumably, since the Mp900 acts
    like a voice modem, I can't imagine why it wouldn't work
    right, but it doesn't)

    Looking forward to hearing back.

  2. Hi Clinton,

    Virtual PC has always required exclusive access to the serial port and
    this has not been changed in VPC SP1. We actually did take a fix in VPC
    SP1 specifically for external modems that may help out here.

    Nope, it doesn't work. In fact, if you change the com
    port settings, you find that VPC reports it can't get
    access to the com port the second time, so there is
    definitely something wrong.

    I suggest that someone in development break out a copy of
    Win95, a MP900 from storage (hey, its microsoft, they
    gotta have some somewhere!) and find out why it doesn't
    work right, because the idea that MICROSOFT hardware
    won't run under a microsoft OS in an MICROSOFT VIRUTAL
    MACHINE has got to be embarrasing.

    Admittedly, Microsoft's support of their hardware (legacy
    esp, but not just legacy support) has a pretty embarsing
    history, and I gotta tell you, I am GLAD I didn't buy MS
    usb speakers or a MS networking product, and I'm NEVER
    gonna buy that watch, simply because its likely to get
    cancelled and dropped like dead fish long before they get
    it right.

    <rant> Ok, I'm annoyed, but then I've bought MS joysticks
    (unsupported now), wheels (unsupported now),
    forcefeedback devices (unsupported), 900mhz phone
    (unsupported since almost the day it was made), voice
    puck (unsupported now), game pads (unsupported now),
    keyboards and mice (thank goodness those were already
    standard technology!) - Maybe, if microsoft can't be
    bothered to continue supporting some of this hardware,
    maybe they can open source their previous efforts so that
    the rest of us can continue to support them. </rant>
