# Line Settings

## Baud Rate

Select the baud rate by choosing a standard baud rate from the list or typing one in. Serial allows you to use extended baud rates with devices that support it.

## Data Bits

Set the number of data bits, normally 8.

## Parity

Set the type of parity, even or odd. Parity is a single-bit error detection code.

If the parity bit is present but not used, it is referred to as mark parity (when the parity bit is always 1) or space parity (the bit is always 0). If the device supports these they will also be available as options.

## Stop Bits

Set the number of stop bits, normally 1.

## Line Delay

Insert a delay after each line ending sequence is encountered in the transmitted data stream.

## Character Delay

Insert a delay after each character transmitted.

## Flow Control

Method | Description
--- | ---
XON/XOFF | Stop transmitting data to the device whenever we receive an XOFF (Ctrl-S) character, and resume once we’ve received XON (Ctrl-Q). Serial will use hardware support where available for reduced latency.
RTS/CTS | Transmit data when CTS is active, or suspend it otherwise.
DTR/DSR | Transmit data when DSR is active, or suspend it otherwise.
