i use a motorola GPS card as my server, and the driver i choose is the 
oncore driver(type 30). my linux version is 2.4.20 with pps patch, and the 
ntp version is 4.1.2. after ntpd configured the card, it was most likely 
just stay at some position to wait for the some condition to be satisfied. 
in the log file 'clockstats' it print the following sentences time and time 
again. 52857 53939.486 127.127.30.0 Resetting timing to Assert.
52857 53939.486 127.127.30.0 HARDPPS Set.
52857 53966.208 127.127.30.0 Resetting timing to Assert.
52857 53966.208 127.127.30.0 HARDPPS Set.

in the ntpq, i try cl command, and it prints below where the 'noreply' 
always equals to 'poll'-2.
status=0101 clk_noreply, last_clk_noreply,
device="Motorola Oncore GPS Receiver", timecode=, poll=948, noreply=946,
badformat=0, baddata=0, fudgetime1=0.000, stratum=0, refid=GPS, flags=4

anybody knows what the ntpd is waiting for? i am very sure that the pps and 
the serial signal have been received by the PC.
