6 * generic reference clock driver for several DCF/GPS/MSF/... receivers
9 * On systems that support PPSAPI (RFC2783) PPSAPI is the
10 * preferred interface.
12 * Optionally make use of a STREAMS module for input processing where
13 * available and configured. This STREAMS module reduces the time
14 * stamp latency for serial and PPS events.
15 * Currently the STREAMS module is only available for Suns running
16 * SunOS 4.x and SunOS5.x.

56 * This driver currently provides the support for
57 * - Meinberg receiver DCF77 PZF535 (TCXO version) (DCF)
58 * - Meinberg receiver DCF77 PZF535 (OCXO version) (DCF)
59 * - Meinberg receiver DCF77 PZF509 (DCF)
60 * - Meinberg receiver DCF77 AM receivers (e.g. C51) (DCF)
63 * - Schmid clock (DCF)
64 * - Conrad DCF77 receiver module (DCF)
65 * - FAU DCF77 NTP receiver (TimeBrick) (DCF)
66 * - WHARTON 400A Series clock (DCF)
68 * - Meinberg GPS receivers (GPS)
69 * - Trimble (TSIP and TAIP protocol) (GPS)
71 * - RCC8000 MSF Receiver (MSF)
72 * - VARITEXT clock (MSF)
76 * Meinberg receivers are usually connected via a
77 * 9600/7E1 or 19200/8N1 serial line.
79 * The Meinberg GPS receivers also have a special NTP time stamp
80 * format. The firmware release is Uni-Erlangen.
82 * Meinberg generic receiver setup:
83 * output time code every second
86 * Meinberg GPS receiver setup:
87 * output time code every second
90 * This software supports the standard data formats used
91 * in Meinberg receivers.
93 * Special software versions are only sensible for the
94 * oldest GPS receiver, GPS16x. For newer receiver types
95 * the output string format can be configured at the device,
96 * and the device name is generally GPSxxx instead of GPS16x.
98 * Meinberg can be reached via: http://www.meinberg.de/

288 ** displayed. the time units for a message class will also be displayed.

4929 * This driver supports the Trimble SVee Six Plus GPS receiver module.
4930 * It should support other Trimble receivers which use the Trimble Standard
4931 * Interface Protocol (see below).
4933 * The module has a serial I/O port for command/data and a 1 pulse-per-second
4934 * output, about 1 microsecond wide. The leading edge of the pulse is
4935 * coincident with the change of the GPS second. This is the same as
4936 * the change of the UTC second +/- ~1 microsecond. Some other clocks
4937 * specifically use a feature in the data message as a timing reference, but
4938 * the SVee Six Plus does not do this. In fact there is considerable jitter
4939 * on the timing of the messages, so this driver only supports the use
4940 * of the PPS pulse for accurate timing. Where it is determined that
4941 * the offset is way off, when first starting up ntpd for example,
4942 * the timing of the data stream is used until the offset becomes low enough
4943 * (|offset| < CLOCK_MAX), at which point the pps offset is used.
4945 * It can use either option for receiving PPS information - the 'ppsclock'
4946 * stream pushed onto the serial data interface to timestamp the Carrier
4947 * Detect interrupts, where the 1PPS connects to the CD line. This only
4948 * works on SunOS 4.1.x currently. To select this, define PPSPPS in
4949 * Config.local. The other option is to use a pulse-stretcher/level-converter
4950 * to convert the PPS pulse into a RS232 start pulse & feed this into another
4951 * tty port. To use this option, define PPSCLK in Config.local. The pps input,
4952 * by whichever method, is handled in ntp_loopfilter.c
4954 * The receiver uses a serial message protocol called Trimble Standard
4955 * Interface Protocol (it can support others but this driver only supports
4956 * TSIP). Messages in this protocol have the following form:
4958 * <DLE><id> ... <data> ... <DLE><ETX>
4960 * Any bytes within the <data> portion of value 10 hex (<DLE>) are doubled
4961 * on transmission and compressed back to one on reception. Otherwise
4962 * the values of data bytes can be anything. The serial interface is RS-422
4963 * asynchronous using 9600 baud, 8 data bits with odd party (**note** 9 bits
4964 * in total!), and 1 stop bit. The protocol supports byte, integer, single,
4965 * and double datatypes. Integers are two bytes, sent most significant first.
4966 * Singles are IEEE754 single precision floating point numbers (4 byte) sent
4967 * sign & exponent first. Doubles are IEEE754 double precision floating point
4968 * numbers (8 byte) sent sign & exponent first.
4969 * The receiver supports a large set of messages, only a small subset of
4970 * which are used here. From driver to receiver the following are used:
4974 * 21 Request current time
4976 * 2C Set/Request operating parameters
4977 * 2F Request UTC info
4978 * 35 Set/Request I/O options
4980 * From receiver to driver the following are recognised:
4985 * 44 Satellite selection, PDOP, mode
4986 * 46 Receiver health
4987 * 4B Machine code/status
4988 * 4C Report operating parameters (debug only)
4989 * 4F UTC correction data (used to get leap second warnings)
4990 * 55 I/O options (debug only)
4992 * All others are accepted but ignored.
