Change 135218 by rrs@rrs-mips2-jnpr-2 on 2008/02/11 20:13:45

	Work around (option) for the Cavium emulator.
	The telnet console to the emulator runs in cooked (line input) mode, this causes
	ddb to get confused about its character inputs. This change flushes the input line
	after single-character input (the pager) and tosses '\r' input.
