- * This driver supports the PSTI 1010 and Traconex 1020 WWV/WWVH
- * Receivers. No specific claim of accuracy is made for these receiver,
- * but actual experience suggests that 10 ms would be a conservative
- * assumption.
- * 
- * The DIPswitches should be set for 9600 bps line speed, 24-hour day-
- * of-year format and UTC time zone. Automatic correction for DST should
- * be disabled. It is very important that the year be set correctly in
- * the DIPswitches; otherwise, the day of year will be incorrect after
- * 28 April of a normal or leap year. The propagation delay DIPswitches
- * should be set according to the distance from the transmitter for both
- * WWV and WWVH, as described in the instructions. While the delay can
- * be set only to within 11 ms, the fudge time1 parameter can be used
- * for vernier corrections.
- *
- * Using the poll sequence QTQDQM, the response timecode is in three
- * sections totalling 50 ASCII printing characters, as concatenated by
- * the driver, in the following format:
- *
- * ahh:mm:ss.fffs<cr> yy/dd/mm/ddd<cr> frdzycchhSSFTttttuuxx<cr>
- *
- *	on-time = first <cr>
- *	hh:mm:ss.fff = hours, minutes, seconds, milliseconds
- *	a = AM/PM indicator (' ' for 24-hour mode)
- *	yy = year (from internal switches)
- *	dd/mm/ddd = day of month, month, day of year
- *	s = daylight-saving indicator (' ' for 24-hour mode)
- *	f = frequency enable (O = all frequencies enabled)
- *	r = baud rate (3 = 1200, 6 = 9600)
- *	d = features indicator (@ = month/day display enabled)
- *	z = time zone (0 = UTC)
- *	y = year (5 = 91)
- *	cc = WWV propagation delay (52 = 22 ms)
- *	hh = WWVH propagation delay (81 = 33 ms)
- *	SS = status (80 or 82 = operating correctly)
- *	F = current receive frequency (4 = 15 MHz)
- *	T = transmitter (C = WWV, H = WWVH)
- *	tttt = time since last update (0000 = minutes)
- *	uu = flush character (03 = ^c)
- *	xx = 94 (unknown)
- *
- * The alarm condition is indicated by other than '8' at A, which occurs
- * during initial synchronization and when received signal is lost for
- * an extended period; unlock condition is indicated by other than
- * "0000" in the tttt subfield at Q.
- *
- * Fudge Factors
- *
- * There are no special fudge factors other than the generic.
