Yes. I'm using Putty with the following settings:
9600 - 8 - N - 1 - N
Flow Control - None.
While the controller is in the process of booting, nothing displays on the console session. Once boot is complete I can press CTL-G and it displays the SP console. If I press CTL-D to go back to the console session, nothing displays, and I get no response from the keyboard.
The fas2240-4 has been off for a while, so I was thinking it may be related to a low NVRAM battery. It's been charging for about 15 hours now, but I still can't get the session output.
I also tried another console cable, and got the same results. What's weird is that I can get into the SP console via the serial console with the CTL-G and it displays and works via the serial console, but when I press CTL-D to go back to the seriel console, nothing is displayed.
