GPS Data Logger Software - BT747

Hi,

I am happily using bt747 with my Holux m-241 logger for quite a while now.
Since I just startet using bt747 more often I have the following three questions / feature requests:

1.: When I use the Holux m-241 .bin file (containing several tracks) as input and convert it to a GPX then the GPX-file contains only a single big track. The several tracks are combined to one big one.
Is there a way to conserve the division into several tracks in the GPX file?

I have a Holux M-241, and Ubuntu 9.04 I have set up my rfcomm0 config to connect to the GPS, so I can definatly connect...I think however when I try to connect using /dev/rfcomm4 I get 23984 - Classgps.connection.GPSRxTxPort and nothing else happns.. can you help?
