# Write Line
# Serial Write Line
Writes a string and a new line character (`\r\n`) to [serial](/device/serial).
Write a string to the [serial](/device/serial) port and start a new line of text
by writing `\r\n`.
```sig
serial.writeLine("");
```
### Parameters
* `line` is the [string](/reference/types/string) to write to the serial port
### Example
This program writes the word `BOFFO` to the serial port repeatedly.
```blocks
basic.forever(() => {
serial.writeLine("BOFFO");
basic.pause(5000);
});
```
### Example: streaming data
The following example constantly checks the [compass heading](/reference/input/compass-heading) and sends the direction to serial.
