Dear Eric, Paul, and Charles

I realy appreciate your enlightment.
I tried to use gpsfeed+ and SOCAT (to create virtual tty)
Unfortunately SOCAT strip out any cr/lf of each sentence ... so my twisted-python can not detect of incoming sentence

Now I use gpsfake .... and fortunately I have a "real" gps log onhand

Again .. I really appreciate your enlightment.

in addition to gpsfake, there's an old tcl script floating around the
net called gpsfeed+.  it's a bit primitive, but i've used it in the
past when testing RoadMap.  ah, here:

an advantage over gpsfake (i think) is that you don't need logfiles
from a "real" gps unit -- gpsfeed can create GPS data from scratch,
and simulate travel in a few shapes -- circle, square, etc.  it's a
handy tool for some kinds of testing.
gpsfeed is rather inflexible in what it can generate, however.  Someday
I'll find somebody who can turn satellite ephemerdes into sky positions
in Python - themn gpssim will work and be much, much better.
