Warmpoll
While checking how to use printer port, I encountered a new word "Warmpoll". It comes with/since Windows XP. Here's some note.
It seems Warmpoll supervises printer port some how to detect some signal changes. Then it try to interact with the device at printer port.
If the device is marked 'unknown', Warmpoll keep checking for 1 minute.
then it give up and keep silent until XP shutdown.
In the registry
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Parport\Parameters]
, creating a new key with non-zero value.
DisableWarmPoll"=dword:00000001
, then reboot!
This may disable the WarmPoll.
It seems Warmpoll is driven by parport.sys.
It seems trying to detect IEEE1284 devices.
