BD parameter to vary from the sent parameter. Sending ATBD without an associated parameter value
returns the value actually stored in the device’s BD register.
The following table provides the parameters sent versus the parameters stored.

CS (DO2 Configuration)
Sets or displays the behavior of the DO2 pin signal. This output can provide RS-232 flow control and
controls the TX enable signal for RS-485 or RS-422 operations.
By default, DO2 provides RS-232 Clear-to-Send (CTS ) flow control.
