ser.open() ：打开端⼝‘。ser.close()：关闭端⼝。ser.read()：从端⼝读字节数据。默认1个字节。ser.read_all():从端⼝接收全部数据。ser.write("hello")：向端⼝写数据。ser.readline()：读⼀⾏数据。ser.readlines()：读多⾏数据。in_waiting()：返回接收缓存中的字节数。flush()：等待...

运行cmd:输入pip install pyserial,安装pyserial模块。这里已经安装过该模块,如下: 实现的功能:开1M波特率打印串口接收到的信息。运行脚本之前,将USB转串口工具插入PC USB口;打开设备管理器,查看需要设置哪个COM口;脚本中增加脚本参数解析,运行脚本时指定串口号,波特率默认1M,也可以参数指定波特率,按Ctr+C退出脚本运行。
此外,您正在从端口读取两次;你可能想要做的是: i=0 for modem in PortList: for port in modem: try: ser = serial.Serial(port, 9600, timeout=1) ser.close() ser.open() ser. write("ati") time.sleep(3) read_val = ser.read(size=64) print read_val if read_val is not '': print ...
