Usage of Pyserial and Pexpect in Windows












1















I have a script which functions perfectly in Ubuntu, however my desire is to get this working on a Windows machine for use in a Production environment. The general purpose of this script is to program a PCB.



I am having issues both researching and adapting this section of the code:



try: 

  fd = serial.Serial(Port, Baud) #Opens the specified port

  child = pexpect.fdpexpect.fdspawn(fd, timeout=180)

except:

  input('There has been an error making the connection, check your connections and try againnPress enter to exit')

  sys.exit()

input('Press enter to continue, then apply 24V power to the unit')


The issue being with: 



child = pexpect.fdpexpect.fdspawn(fd, timeout=180)


Any advice or modifications are much appreciated!
