ＳＴＣ单片机的串口模块可以采用Ｔ１定时器作为它的波特率发生器，同时其内部也集成了一个独立波特率发生器作为串口的波特率发生器，本例子采用的是常用的Ｔ１定时器作为它的波特率发生器-STC microcontroller serial port T1 timer module can be used as its baud rate generator, while its interior also incorporates an independent Baud Rate Generator as the baud rate generator, is used in this example uses the T1 timer device as its baud rate generator
