I remember I have seen the similar question before in
this list, but I can only get around 200 posted emails
by using email newsgroup. Appreciate if anyone can
tell me how to check all the emails.

I have a time server with 1pps output. The width of
the pulse is around 20us. I know generally people will
use a gadget box to enlarge the pulse to around 100us
to fit 1bit as 9600bps com port.   

Is it possible for me to set the bit rate to 56K? So
20us pulse can be treat as one bit width; therefore,
ntp can lock the edge of pulse?
