python调用串口，写入数据

#!/usr/bin/python3
 
import serial
 
def serialTest():
 try:
 port = "COM3"
 bps = 115200
 timeO = 5
 ser = serial.Serial(port, bps, timeout = timeO)
 result = ser.write("python invoke serial".encode("gbk"))
 print("write data: ", result)
 ser.close()
 except Exception as e:
 print("ERROR: ", e)
 
if __name__ == "__main__":
 serialTest()
