Post subject:  Reset or Reinitialte Serial Connection

Hi everyone,

Im currently communicating with a motor controller VIA the USB port of the Raspi.
For the communication I am using the CAA library.
From time to time it happens, that a com port is opened multiple times without beeing closed and that causes an error (5802 - unfortunately i never found a real documentation for the error code).

My question is if it is somehow possible to reset or reinitiate the com connection using any command so that I can open and work with the port again without disconnecting the USB plug.

Thanks for any help.
