 ### Interrupt Behavior
 | Value of A | Action | Energy cost | Result |
 | --- | --- | --- | --- |
-| `0` | `COMPORT_SELF_CLEAR` | `0 kJ` | Clears the console screen and the internal message buffer. |
+| `0` | `COMPORT_BUFFER_CLEAR` | `0 kJ` | Clears the internal message buffer. |
 | `1` | `COMPORT_POLL` | `4 kJ` | Copy all internal buffer messages to memory at X, sets B to the number of messages copied |
 | `2` | `COMPORT_FRONT_PORT_OUT` | `20 kJ` | Copies 8 words starting from the address in X to the object directly in front of the cubot if this object has a Universal Com Port as well. The B register is set if the operation succeeded, it is reset otherwise  |
 | `3` | `COMPORT_SELF_OUT` | `1 kJ` | Copies 8 words starting from the address in X to the internal message buffer. The B register is set if the operation succeeded, it is reset otherwise |
+| `4` | `COMPORT_CONSOLE_CLEAR` | `0 kJ` | Clears the console. |
 
 Note that a Cubot can send a message to another Cubot's internal buffer, which will be emptied into his console screen. Currently, the [Radio Tower](https://github.com/simon987/Much-Assembly-Required/wiki/Radio-Tower) is the only other object with a Com Port.
