mount -o remount,ro /
dd if=/dev/mtd0 of=/tmp/flash-backup.img bs=128k
sz -b /tmp/flash-backup.img

That'll copy the contents of flash to a file on the ramdisk in /tmp  
(after remounting the / filesystem read-only so there are no writes  
happening during the dd).  The "sz" command then initiates a send  
over the serial port using the zmodem protocol.
