I am not sure, but maybe you need to change the state of one of the serial lines from Girder?

When i remove the usb to rs232 adapter,and replug it ,the serial reciever can wakeup computer only once again

i think com port may be used by girder4 Serial plugin, COM Port been occupied without the release of Serial plugin, not to awaken again, how to use G4 Serial Plugin write LUA Script to close COM port while computer standby, and automatically Open COM Port while computer wakeup?
