About the Console Download Function
You can use console download, which is a ROM monitor function, to download either a software image
or a configuration file over the voice gateway console port. After download, the file is either saved to the
mini-flash memory module or to main memory for execution (image files only).
Use the console download function when you do not have access to a TFTP server.
Note If you want to download a software image or a configuration file to the voice gateway over the console
port, you must use the ROM monitor dnld command.
Note If you are using a PC to download a Cisco IOS image over the voice gateway 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 bps
or less when downloading a Cisco IOS image over the console port.
Command Description
The syntax for the xmodem console download command is xmodem [-c-y] destination_file_name.
• -c—Optional. Performs the download using 16-bit cyclic redundancy check (CRC-16) error
checking to validate packets. Default is 8-bit CRC.
• -y—Optional. Sets the voice gateway to perform the download using Ymodem protocol. The default
is Xmodem protocol. The protocols differ as follows:
–
Xmodem supports a 128-block transfer size. Ymodem supports a 1024-block transfer size.
