^P should toggle the console mode between talking to the 11/44 serial port

comes back with a >>> prompt then as Jay said something is funky with your
MFM module. IIRC if you put the front panel switch to the locked position
if forces 'program' mode and ^P is ignored, all characters go to the 11/44.
I tried the suggestion from Don with the M9302 in
the last slot of the
11/44 backplane. To my surprise, when you hit ^P, the system prints a
new "(Program)" line and the cursor (_) moves to the next line.
So, now I am thinking ... a wrong/dead terminator on the RL02 drive,
can it have such an effect that through the RL11 controller the bus
hangs?!
IF you changed the dipswitches on the UBI board as I mentioned in my
previous email, AND you get the same response as above (^P gives
another (program) display)... then I bet your front panel board (slot
1AB) or your MFM board is toasty.
