GPS Data Logger Software - BT747

Hi

i'm trying to get bt747 to work on my kubuntu 9.04 with holux m241(v 1.12)

i can start bt747 (v 1.68.25)with sudo ./run_j2se.sh . connecting works only with speed 115200, otherwise it does nothing. device is /dev/ttyUSB0. click on download does nothing, but gets a lot of output in the console(see attachment).

any ideas what i could try or i do wrong?
what log could help to get to the problem?

thx for your help

I had a report recently about BT747 crashing when trying to make a connection on a Intel Core 2 Duo running "Debian GNU/Linux unstable (sid), package 6b14-1.5~pre1-3".

BT747 1.68.5 was using RxTx 2.1.7 - the currently stable version of RxTx and the crash reported:
# Problematic frame:
# C [librxtxSerial.so+0x6462] read_byte_array+0x52
