 * Things to do:
 
-** On some systems gpsd doesn't pull DTR low when closing the GPS.
-
-Reported by Robert E. Anderson <rea@q.sr.unh.edu>.  He tells us this seems
-to have been introduced since 1.98.  The 1.98 code looked like this:
-
-void serial_close()
-{
-    if (ttyfd != -1) {
-	if (isatty(ttyfd)) {
-#if defined (USE_TERMIO)
-	    ttyset.c_cflag = CBAUD & B0;
-#else
-	    ttyset.c_ispeed = B0;
-	    ttyset.c_ospeed = B0;
-#endif
-            tcsetattr(ttyfd, TCSANOW, &ttyset);
-	}
-	/* Restore original terminal parameters */
-	/* but make sure DTR goes down */
-	ttyset_old.c_cflag |= HUPCL;
-	tcsetattr(ttyfd,TCSANOW,&ttyset_old);
-
-	close(ttyfd);
-	ttyfd = -1;
-    }
-}
-
-The new code looks like this:
-
-void gpsd_close(struct gps_session_t *session)
-{
-    if (session->gNMEAdata.gps_fd != -1) {
-	if (isatty(session->gNMEAdata.gps_fd)) {
-	    /* force hangup on close on systems that don't do HUPCL properly */
-	    cfsetispeed(&session->ttyset, (speed_t)B0);
-	    cfsetospeed(&session->ttyset, (speed_t)B0);
-	    tcsetattr(session->gNMEAdata.gps_fd, TCSANOW, &session->ttyset);
-	}
-	/* this is the clean way to do it */
-	session->ttyset_old.c_cflag |= HUPCL;
-	tcsetattr(session->gNMEAdata.gps_fd,TCSANOW,&session->ttyset_old);
-	close(session->gNMEAdata.gps_fd);
-    }
-}

-It looks as though there may be something wrong with cfsetispeed() and/or 
-cfsetospeed() in rea's environment.
+** Figure out how to probe for whether the GPS is a SiRF-II or not.
+
+Shipping $PSRF105,0*3E\r\n ought to elicit an $Ack 105 response
+from SiRF-II chipsets, but I haven't been able to make this work yet.
+We'd get several things from this, including knowing when we can change
+baud rates.
 
 ** Do the research to figure out just what the heck is going on with status bits
