Windows 10: which COM port to connect my switch console

I was not able to connect to my switch console with COM Serial Port. I check the device manager found two : Standard Serial Over BluetoohCOM3 and Standard Serial Over BluetoohCOM4.


I tried serial connection using Putty to connect both COM3 and COM4 but it doesnt work. What is my serial port number?

good console ports?

Anything that isn't a FPS. There's too many "console ports" to list.

 

good console ports?

I would suggest Batman AA as the first console port anybody should play. That's just my opinion though.

 

How to factory reset Cisco 1700 Router

Hopefully I can help you here....its a very common thing to happen.


First, I take it you dont know the passwords for console access or telnet/ssh?

I will assume that these devices belong to you.

step 1. Plug a cisco console cable into a serial port on your pc
step 2. Plug other end into Cisco console port
step 3. Using hyperterm or putty or similar connect to the serial port
step 4. boot router, and make sure you clearly can see the output (this confirms you have good serial comms)
step 5. if this fails, adjust the comm port settings (9600, 8,1,n are the default)
step 6. now you have to do the only hard part...send the break command:

Break command list: Break Commands

Go down the list and match your OS and SW and try the sequence suggested.

If this fails several times do what I do: Install putty (free) and then to send a break so you can get into rommom just hit "ctrl-a b".
