Telit 863-GPS SiRF Binary Format Problem

I have 863-GPS interface board and Telit EVK2.

My problem is that I can’t see SiRF Binary Format via rs-232 com port.

I have two connectors on 863-GPS interface board set in the middle like it is in manual and Telit should send SIRF Binary Format on the second rs-232 port.

I have only at command connections and python script.

By the way is it possible to use AT command to decode GPS data: almanac, ephemeris and pseudoranges?

I need to decode this information somehow and use them in python script.
