>(interrupt handler code)

Eli has told you what to do. But if you still need to use printf, try this
code (untested - it may need slight modification).

      void timer_handler()
      {
	char str[100];
	char *ptr = str;
	unsigned offset = 0xb8000;

	sprintf(str, "Tics passed: %d", ++tics);
	while (*ptr) {
		_farpokeb(_dos_ds, offset++, *ptr++);
		offset++;
	}
      }

I'm under the impression that sprintf should work even in an interrupt
handler. So, if the code still fails, it should be due to sprintf.
