Basic resets the value at $6F so you can't POKE it and then enter a command like 
DIR. The value at $6F will have been changed by the ROMs.
I did find a method for forcing the DIR routine to reset $6F by making the 
routine at $CCC5 "Send directory routine to console out" branch to code setting 
$6F and then returning to the ROM code.
So coupled with a routine using the $167 vector and testing for a device value 
of -2, DIR output will go to the printer.
