Doesn't read-all leave mark track recognition to software?

However, more "intelligent" controllers
do all this processing of the
mark track to identify start and end of block/tape, and all other
processing, in the controller. Can you make them read out the contents
and do the processing if you have different control codes?
The state machine implemented in hardware for all the intelligent DECtape
controllers will not recognize the 4-bit LINCtape codes at all, since the
DECtape codes are 6 bits long. You'll just get a MARK Error.
