GT-730FL-S doesn't work after changing baud-rate to 9600

[Google Code Exporter]

I have a GT-730FL-S, Debian 2.6.32-5-686
I'm using skytrack-datalogger recompiled with -DDEBUG_ALL flag

I have changed the baud-rate to 9600 with --set-baud-rate and --permanent
Now the baud-rate is 9600 but i can´t connect to the GPS.

the output:

# ./skytraq  --info
testing for 9600 baud-rate
timeout hit
len=90
current ascii output: 
received 90 bytes
buffer as ascii contains: �
found needle at offset 50
NMEA detection succeeded
detected speed is 9600
>>> 
Waiting for ACK with msg id 0x17
skytraq_read_next_package
skytraq_read_next_package
skytraq_read_next_package
No response from datalogger.


Any Ideas to solve the Problem?

I tried to use the original Windows Software, but there is also a connection 
problem
