| size_t Serial::read | ( | uint8_t * | buffer, |
| size_t | size | ||
| ) |
Read a given amount of bytes from the serial port into a given buffer.
The read function will return in one of three cases: * The number of requested bytes was read. * In this case the number of bytes requested will match the size_t returned by read. * A timeout occurred, in this case the number of bytes read will not match the amount requested, but no exception will be thrown. One of two possible timeouts occurred: * The inter byte timeout expired, this means that number of milliseconds elapsed between receiving bytes from the serial port exceeded the inter byte timeout. * The total timeout expired, which is calculated by multiplying the read timeout multiplier by the number of requested bytes and then added to the read timeout constant. If that total number of milliseconds elapses after the initial call to read a timeout will occur. * An exception occurred, in this case an actual exception will be thrown.
| buffer | An uint8_t array of at least the requested size. |

Reads from the serial port until a single line has been read.

| vector< string > Serial::readlines | ( | size_t | size = 65536, |

Reads in multiple lines until the serial port times out.
This requires a timeout > 0 before it can be run. It will read until a timeout occurs and return a list of strings.

| eol | A string to match against for the EOL. |
| void Serial::sendBreak | ( | int | duration | ) |

Sets the baudrate for the serial port.
Possible baudrates depends on the system but some safe baudrates include: 110, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 56000, 57600, 115200 Some other baudrates that are supported by some comports: 128000, 153600, 230400, 256000, 460800, 921600

| void Serial::setTimeout | ( | serial::Timeout & | timeout | ) |
Sets the timeout for reads and writes using the Timeout struct.
There are two timeout conditions described here: * The inter byte timeout: * The inter_byte_timeout component of serial::Timeout defines the maximum amount of time, in milliseconds, between receiving bytes on the serial port that can pass before a timeout occurs. Setting this to zero will prevent inter byte timeouts from occurring. * Total time timeout: * The constant and multiplier component of this timeout condition, for both read and write, are defined in serial::Timeout. This timeout occurs if the total time since the read or write call was made exceeds the specified time in milliseconds. * The limit is defined by multiplying the multiplier component by the number of requested bytes and adding that product to the constant component. In this way if you want a read call, for example, to timeout after exactly one second regardless of the number of bytes you asked for then set the read_timeout_constant component of serial::Timeout to 1000 and the read_timeout_multiplier to zero. This timeout condition can be used in conjunction with the inter byte timeout condition with out any problems, timeout will simply occur when one of the two timeout conditions is met. This allows users to have maximum control over the trade-off between responsiveness and efficiency.
Read and write functions will return in one of three cases. When the reading or writing is complete, when a timeout occurs, or when an exception occurs.
A timeout of 0 enables non-blocking mode.
| timeout | A serial::Timeout struct containing the inter byte timeout, and the read and write timeout constants and multipliers. |

| void Serial::waitByteTimes | ( | size_t | count | ) |
| bool Serial::waitForChange | ( | ) |
Blocks until CTS, DSR, RI, CD changes or something interrupts it.
Can throw an exception if an error occurs while waiting. You can check the status of CTS, DSR, RI, and CD once this returns. Uses TIOCMIWAIT via ioctl if available (mostly only on Linux) with a resolution of less than +-1ms and as good as +-0.2ms. Otherwise a polling method is used which can give +-2ms.
