Hello,

I'm trying to reset the password on an MD3420 using a Serial Cable connection.

I set my terminal session to the following parameters:
Bits per second: 115200
Data bits: 8
Parity: none
Stop bits: 1
Flow control: none

I press CTRL + Break then S however nothing happens. I’m unable to see the Service Interface Main Menu. When I disconnect the module from the controller or when I reboot the controller I’m able to see text on the screen but when I try to input commands I doesn’t take them. It’s like I’m in read only mode.

Things I already attempted:

Removed modules

Removed battery from modules

Restarted controller

Please help!
