Microsoft serial mouse driver initialization

I have an application where I need a PC running Win2K to recognize a
serial mouse and work with it even if it is disconnected when the PC
originally boots up (this is after the driver has been installed and
the mouse is working fine and the PC is then rebooted). I have tried
setting the following in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Sermouse\Parameters
OverrideHardwareBitstring REG_DWORD (Set to 1 for COM1)

The above supposedly specifies that regardless of whether it was
actually detected, a serial mouse is present on the system.

But after bootup when I connect the serial mouse, it is not detected.
The only way I can get it to work at this point is to go into Device
Manager and have it scan for newly added PNP hardware.

Any suggestions would be appreciated.

Click to expand...

Well, the obvious workaround is to use a USB mouse
instead of serial... I'm not aware of any way to make
Win2K autodetect a serial device.
