I have a Dell PowerConnect 3548P and I think the only way for me to configure it is through the console port on the back which is serial. It came with a Serial to Ethernet cable that is connected to my laptop.
I open putty with the specified settings, but I can't connect to it for some reason. I use COM1 to 5 and all come back with no connection.
What COM port should I be using after specifying serial?
