Feb 15, 2015 Hello, I am trying to use Putty to connect to a Cisco router via a serial connection. This is to configure the router out of the box. Security is not a problem until it is connected to a network. Then it will be confgured with SSH. Serial line: /dev/ttyUSB0 Baud rate: 9600 Data bits 8 stop bits 1 Using a Cisco USB serial cable. Hi, I’m attempting to use putty to get a serial window working. I’ve followed the tutorial in Docs and downloaded the patch etc. Solved Using PuTTY as a serial connection. But I can’t start another debug session because I get the same “Unable to open connection to COM3 Unable to open serial port”.message.
Cannot Open Serial Port
I wanted to create a serial Connection in putty with my raspberry pi 3.I don't know what I have done wrong. But I get Always the same error message that my serial port can not be open.I'm sure that the Settings are Right. My PI has 2 usb ports. I tried both of them but None worked.Thanks!!
