* 2000-03-18 Jim Van Zandt: Fix polling.
* Eliminate dtlk_timer_active flag and separate dtlk_stop_timer
* function. Don't restart timer in dtlk_timer_tick. Restart timer
* in dtlk_poll after every poll. dtlk_poll returns mask (duh).
* Eliminate unused function dtlk_write_byte. Misc. code cleanups.
