Are you certain the electrical connection is correct, correct RS232 voltages
and correct polarity.  The polarity of the serial data and the control
signals is  reversed from each other.   Can you place a scope on the PPS
signal at the serial port.  You problem looks to me as if either (1) there
is not PPS signal) or (2) there is no interrupt handler (deriver) catching
the PPS.
