A couple of general questions about this (I don't know the background 
material in enough detail, so pardon if some of these are "obvious"):

1. Does this support (calibrated) sources with frequency other than
    1 Hz?
2. I assume that with the PPS line discipline loaded you can still read
    the data from the main pins on the serial port (almost always used
    for metadata?)

And a minor note: you use the term CD (Carrier Detect), but in most 
references the pin is labelled DCD (Data Carrier Detect).
