This driver supports the Ultralink Model 320 RS-232 powered WWVB receiver. While the unit may support them, this driver does nothing with leap seconds, quality codes, etc. Any mistakes are mine.
Any improvements are welcome.
DST STD transition indicators Note that this driver does not do anything with the L or T flags. The M320 also has a 'U' command which returns UT1 correction information. It is not used in this driver.
