cout is buffered by default. it is not a good idea to intermix conio 
functions with the standard library routines.

ch is unitialized in this test.

try the following:

#include <conio.h>
#include <dpmi.h>

int main(void) 
{
	int c;
	while((c = getch()) != 27)
	{
		if(c == ' ')
		{
			putch('\a');
			__dpmi_yield();
		}
	}

	return 0;
}
