Keep in mind if you change the baud rate on the Cisco device you’d have to change the baud rate here just like a normal terminal. print z1serial.isopen True for opened if z1serial.isopen: while True: size z1serial.inWaiting() if size: data. The rest you can leave as I’ve configured it for Cisco’s default. As per the usual, they start counting at 0 so mine was port # 2.

In my case, my console cable was connected to COM3, which is the third port. The only thing you will need to change here is the port number, which is the first argument. The first line opens a serial port object for our use. However it presents a problem in that it will block even after there is no more # string type, which we can then properly print.ĭata = serial_port.read(bytes_to_read).decode() decode converts it from a type of ' bytes' to a # This line reads the amount of data specified by bytes_to_read in. While bytes_to_read < serial_port.inWaiting(): # command it had to iterate through the loop twice before all the data arrived. # higher value than what is in bytes_to_read we know that more data is still coming in. This loop sleeps 1 second each iteration and updates bytes_to_read. You can rate examples to help us improve the quality of examples. # 9600 baud is not very fast so if you call serial_port.inWaiting() without sleeping at all it will likely just say These are the top rated real world Python examples of extracted from open source projects. # Give the line a small amount of time to receive data # Make sure there is not any lingering input - input in this case being data waiting to be received

Serial_port = serial.Serial( 2, baudrate= 9600, timeout=None, parity=serial.PARITY_NONE, bytesize=serial.EIGHTBITS, stopbits=serial.STOPBITS_ONE, xonxoff=False)
