Configuration register is 0x0

You can download either a software image or a configuration file via TFTP or via the console port, a 
ROM monitor function over the router console port. After downloading, the file is saved to the Flash 
memory.

Use console download when you do not have access to a TFTP server.

If you are using a PC to download a Cisco IOS image over the router console port at 115,200 bps, ensure 
that the PC serial port is using a 16550 universal asynchronous transmitter/receiver (UART). If the PC 
serial port is not using a 16550 UART, we recommend using a speed of 38,400 or less when downloading 
an Cisco IOS image over the console port.

Configure the PC communications port to match the router console port as follows:

9600 baud

8 data bits

no parity

1 stop bit

Follow the steps below to run Xmodem:

Move the image file to the local drive where the xmodem will execute.

Enter the xmodem command.

Following are the syntax and descriptions for the xmodem console download command:

xmodem [-ucyrx] destination_file_name
