the usage information does not convey that you have to do:
	tpm 1 2 3 4 5 6 7 8 9
perhaps says "<byte> [<byte> ...]" instead ?  and note that you have to 
specify at least 6 ?

also, there's a typo: ressponse -> response

this gets used in one place, and the one place where it does get used, i don't 
see a point in calling cmd_usage().  just have the one place where this is 
used call puts() instead.
