What does the "set cons brk=xx" do ? I tried set cons brk=65 on the z80 simulator, and entered a two instruction program "loop" CTR A, or just "a" or "A" (shift A) don't stop the sim, CTR-E still does. I was hoping to use an alternate brk key for my "GDB problem" (gdb running SIMH running an OS ..... ctr-B trapped by GDB instead of SIMH) Mike
