What's your terminal and cable look like.
It should be null-modem rs232.
The DEC 11/34 uses Xon/Xoff flow control -- not dtr/dsr or cts/rts so those
need to be looped back on the pc if you're using
one as a vt100.
Transmit should go to receive and receive to transmit.  A straight through
cable won't do it.

 I have, what I now know for a fact is the correct lines set up on the
 serial
 console on my 11/34.  the correct signals are coming out according to my
 tester box.  However, I cannot respond to the prompt.
 I started with the diagnostic on the front panel, which says if I hit CLR
 173024 LAD EXA I should get 173000.  I don't.  I get 127777.  According to
 the manual there is something wrong with the M9301 or the switches are set
 wrong, and all the switches are ON.  Do you guys know of anything else
 that
 could be the case?  I do get different results whether or not I hook up
 the
 faston tabs going to the front panel or not - I get 177777 if I don't hook
 them up at address 173024.
 Any help would be much appreciated, as always.
