I've been going over NTPD docos (I wish O'Reilly would publish a book on this!) and get conflicting reports about whether or not PPS (pulse per second on DCD) is supported in the linux serial driver. I have a totally accurate clock (TAC-2) from TAPR.ORG which is a GPS receiver that puts out PPS accurate to within 10usec (in addition to NMEA). The problem is that NTP doesn't seem to be syncing on the PPS signal arriving on the DCD pin. I've verified with a LED that DCD is oscillating at 1Hz. This is probably pilot error configuring NTP but thought I'd ask if the linux serial driver has built-in support or not.
