serial port with aleready existing active connection

[benzaouia]

I have issue with my SSH service in VM, I try to fix it using serial port connection, I can take this connection but every time I want to reconnect by serial port I have to restart the VM, because the last connection is still active.

I tried in vain send  “~." to serail port input and desabling than ennabling.

My question is How to end active connection and began new one or take over this active connection.

thank you.
