rfcomm0: connection refused

["Virat Gohil" <virat4lug@hotpop.com>]

Hi All,

I tried connecting to GPRS using my nokia 6820 and CSR usbdongle. I am able
to start hcid, sdpd.

I am also able to l2ping my device.

I can bind the device to rfcomm0, after patching the kernel

I was able to connect to The Internet once, but after I restarted I got the
following error while connecting using pppd

rfcomm0: connection refused!

I thought may be I messed up a setting here or there, so I re-installed
RedHat 9.0 and tried again, I was able to conenct once, after I restart I
get the same problem. please help.

The following is the output of hcidump:
