We cannot change DOS system calls, can we?

The possibility of an interactive program to interpret Ctrl-D as EOF 
depends on how it reads its input.  If it does so with standard DOS calls 
(via `read', `getc' or other library functions which call DOS I/O), this 
isn't possible without some very painful tweaking of the program's 
original code (this is a port, remember?).  In contrast, if input is read 
via termios or other console-specific interface, the task is much easier, 
since those I/O methods bypass normal DOS calls.

So what Python does is not necessarily applicable to Perl.
