| description: | |
| DTR pin specification. DTR pin when active tells that the driver that there |
| is active client on the other side of serial line. |
| The device driver does not use DTR for hardware flow control. |
| When device is connected to computer serial converter usually asserts DTR |
| line when serial port is opened and ready for communication. |
| This line can be used in Smartbond(tm) driver to detect remote client presence. |
| If client is not present the device can disable UART, allowing for |
| power system management to enter more efficient power levels. |
