  • Is your terminal application set to 9600 8 N 1?

  • I can't get what you mean exactly for (terminal application). but I am using default terminal of GNS3 and I don't know what it is set to . Commented Jan 5, 2018 at 20:07
  • The baud rate seems fine, you also need to deactivate flow control (no Xon/Xoff nor RTS/CTS).

  • @KarimYousry There are a lot of other great console programs to use with configuring your network equipment. Personally i use TeraTerm, which today is free. With that you can specifically select to deactivate flow control.

I can confirm that accepting the default RAM entry will solve this issue. I was clicking finish without an idle-pc value found. After accepting the default RAM, the wizard found an idle-pc value, and then I was able to finally connect via putty.
