Echoed from the command
If the STATUS field in the response is MPSTATUS_OK, then the request to drop the channel successfully
submitted to the lower layers of the stack.
When the channel drops, an EVT_DISCONNECT event sends to the host.
When at least one connection is active (regardless of profile) the DCD output pin remains asserted.

8.12 Set Modem Lines
Bluetooth Serial Port Profile is capable of exchanging modem signals DTR, DSR, RTS, CTS, DCD, and
RI over air.
From a host’s perspective, it can have DTR, RTS, DCD and RI as output lines.
Note: DCD and RI are outputs for modems and ‘host’ in this context can mean either a PC or a
peripheral like a modem.
Additionally UARTs are capable of sending BREAK signals. BREAK output signals are non-idle state TX
pins for a period much greater than the character width at the current baud rate setting.
