描述
get_serial_paramget_serial_paramGetSerialParamGetSerialParamGetSerialParamget_serial_param returns the current parameter settings of
the serial device passed in SerialHandleSerialHandleSerialHandleSerialHandleserialHandleserial_handle. For a
description of the parameters of a serial device, see

执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
此算子修改后续输入参数的状态：
在执行此算子时，若该参数值需在多个线程间使用，则必须对其访问进行同步。

结果
If the parameters are correct and the parameters of the device could
be read, the operator get_serial_paramget_serial_paramGetSerialParamGetSerialParamGetSerialParamget_serial_param 返回值 2 ( H_MSG_TRUE )。否则将抛出异常。
