在Python中COM口的调用方法

import serialimport timet = serial.Serial('com6', 115200) #USB COM number on your PC and the transfer bit rate of the COM port.print t.portstr #Display the working UART port number on your PC.n = t.write('logcat -c /r')n = t.write('ampclient_samples 2 -O 3 /mnt/media_rw/B278-E25A/video_google_clips/New_Webm/bunny_1080P.webm /r')time.sleep(3)print "Does the stream output normally? Yes=1 or No=2"Input = int(raw_input())if Input == 1:  print "Pass!!!"  n = t.write(chr(0x03)) #Call for Ctrl+C command in UART port  n = t.write('logcat -c /r')else:  print "Fail!!!"  n = t.write(chr(0x03))  #n = t.write('logcat -v threadtime /r')
