非同步資料傳送UART(Universal Asynchronous Receiver / Transmitter),既然是非同步所以RS232傳送的時候必須要有起始BIT和停止BIT,幫助接收者判斷資料已經開始或已經結束。如下圖所示RS232正式使用上方非同步的方式將一串資料傳送給接收端。

In telecommunications, RS-232, Recommended Standard 232[1] refers to a standard originally introduced in 1960[2] for serial communication transmission of data. It formally defines signals connecting between a DTE (data terminal equipment) such as a computer terminal, and a DCE (data circuit-terminating equipment or data communication
