使用RS232串口线或者是RS232转USB的这一类的接口,会需要com口作为接口来进行输入输出调式,
写了个脚本来控制COM口,用到了Python内建的serial库
代码如下:

import serial
import time
def setTout(t):
print "Old Timeout is:[%s]" % po1.getTimeout()
po1.setTimeout(t)
print "New Timeout is:[%s]" % po1.getTimeout()
def sendShell(sp,cmd):
sp.write(cmd + "\n" )
print "send shell cmd:[%s]" % cmd
str = sp.readall()
return str
def shell_io(sp,cmd,sleepTime):
str = sendShell(sp,cmd)
print str
time.sleep(sleepTime)
po1 = serial.Serial( 'com1' , 115200 )
timeStart = time.time()
portnow = po1.portstr
print "COM port now is:[%s]" % portnow
setTout( 5 )
shell_io(po1, "ls" , 2 )
shell_io(po1, "pwd" , 2 )
shell_io(po1, "ls -l" , 2 )
po1.close()
