I find this quite annoying also.  Prior to the availability of OpenDOS 
source, I worked around it by patching DOS.  For example, in DR-DOS
6.0, a dissassembly of IBMDOS.COM reveals

1CC1:0736 3C10          CMP     AL,10
1CC1:0738 750F          JNZ     0749

Changing the JNZ to JMP eliminates the Ctrl-P problem forever.  You
could probably find the same check in other versions of DR-DOS or 
OpenDOS.  (If you've built OpenDOS from source, it's at line 519 ofcio.a86 :-)
