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 :-)
