Important times for a command transmission:

To ensure a safe data transfer, the time gap between two commands should
be at least 250 ms.
The circulator automatically responds to an in command with a data string
followed by a LF (Line Feed). The next command should only be sent after
10 ms.

The out commands are valid only in remote control mode.
