/*! 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.
|
||||||
|
*
|
||||||
|
* \param timeout A serial::Timeout struct containing the inter byte
|
||||||
|
* timeout, and the read and write timeout constants and multipliers.
