Does anyone knows what's the meaning of serail event id 45?
I serach all the web and msdn. No any answers.
This seems a \device\serail1 error. I encountered this problem in some
brand of motherboard.
Thanks!

I think this page found easily by Google give enough information:

In addition to the ideas mentioned there i would certify that the latest
BIOS has been installed and that the BIOS settings has been reset.

Sten:
Thanks for your url hint for eventid 45. I checked the page and got
some questions to be verified.
1. According eventid.net's comment form Alex Boge : " serial port
has malfunctioned or not responded with a valid return to a query
device function call" . What's the "query device function call"
exactly?
2. Is this concerned with SetCommTimeouts()? I wonder if the read
or write timeout cause this event.

Well.. could be DeviceIoControl() but it probably means driver level
functionality in the form of the HAL functions a driver uses to query
hardware ports.

Most probably not. At most it could have something to do with buffer
sizes that driver interpret incorrectly.

What i would try before replacing the port is
a) check if the problem appears with all, some or just one serial port using
application
b) try to see if the FIFO settings in Device Manager -> Ports->com port,
Device
settings page, Advanced button has some effect.
