Sometimes it is and sometimes it isn't.  It's been a while since I  
verified this, but as I recall, the auto CR/LF thingee in the stunt box  
ignores CR and executes a CR & LF on receipt of LF (and automatically  at 
the end of the line).  For pictures with overstrike, that's a  MAJOR 
problem.  It's been a while since I had them on the air, but my  3 M28s 
are all set up different.  Between them, normally at least one  will 
receive correctly.  The three are (if I remember which is  which):

Machine  Unshift on space  Auto CR/LF
M28ASR   Yes                No       Has secondary reperf
M28KSR     No                No   Has 3 speed transmission
M28RO     No                 Yes      In soundproof cabinet



You probably want to enable unshift on space on each machine.  It  generally 
just a screwdriver adjustment on the right side of the stunt box (when  you 
are facing the keyboard) and under the paper roll.  I have detailed  
instructions if anyone needs them.
 
Auto CR/LF is accomplished in two parts. 
 
The first part is technically called non-overline. This is done by  
exchanging the universal code bars in the stunt box in slots 5 and 38.   It's easy as 
no new parts are needed.  But, it does mess up some RTTY  Art.  
 
The second part is called auto CR-LF needs a "zero" code bar,  mod kit is 
157514, and a couple of uncoded universal code bars.  

It's great when unshift on space, non-overline and auto CR/LF  are installed. 
 If you are on-the-air copying or working stations,  especially DX, and 
signal levels are low or there is QSB.
