I am by no means an expert on RSX but it is my recollection also that 
this was the way to break in.  A judicious ^C during startup at the 
console, particularly in V3.2 and prior, would let you in.  Not sure 
about V4.0 and later; that issue may have been addressed.

Might need to do an ATL to see the active tasks and an ABO of one or 
more tasks once at the MCR prompt.
