+## Redirect Serial Output to File in VMware
+
+To change the serial port settings the VM needs to be shut down. Then edit the VM settings and add a new serial device by clicking "ADD NEW DEVICE" on top right and there select "Serial Port".

+
+The serial port should then be connected to a file on the datastore `serial_console`:

+
+These files then can be accessed over `lxsup00.psi.ch:/data/serial_console`.
