I have an IBM 2005-16B switch, and it has a male serial connector on it, and I want to use that to configure the device.
I also have a usb to male serial cable, and I have recently created a null-modem cable based on This pinout.
I connected all up, used linux cu command with 9600 baud rate (I also had to chmod 666 /dev/ttyUsb0) and I didn't get anything on the console output. (Also tried putty on windows, same results).
Do I have to use some other cable, or my switch is basicly broken?
