COM port on PC(Win 8.1 pro) - reset

[PerranOak]

Occasionally, I have an error on a COM port that is resolved by rebooting the machine.

Is there a convenient way to reset/reinitialise without resorting to a reboot?

Cheers.

You can go to:
Device manager -> Ports -> Properties of the com port -> Port Settings tab -> Advanced -> Change port number
then try disable and re-enable it.

The downside is number has now changed.
If you are not using USB COM port already, try that, then it can possibly be unplugged an replugged.
