如何清除串口缓冲区? [英] How to clear the serial port buffer?

问题描述

大家好:)
我正在用C ++/CLI编写应用程序，但是串行传输有问题.在开始时，我得到了一些其他数据，这些数据不应该存在.我正在使用SerialPort类.传输开始之前，可能应清除缓冲区. DiscardOutBuffer()与C中的fflush()类似吗?

Hi All :)
I''m writing an application in C++/CLI and I have a problem with serial transmission. At the beggining, I got some additional data, which are not supposed to be there. I''m using SerialPort class. Probably buffer should be cleared before the transimission starts. Does DiscardOutBuffer() work similar to fflush() in C? Can you please give me any advice?
