Hello to all
I am trying to set up a SCO connection between 2 PCs, one with kernel 2.6.1=
8 and one with kernel 2.6.17. After several tries with sco-sockets I tried =
the scotest program with which I have the same problems as with my own sock=
et-program. The data seems to be sent (according to the output of hcidump -=
X -V), but it is not received. I have two Bluegiga Dongles with a CSR Bluec=
ore 4 External chip connected via USB to a USB2.0 PCI-Card in each PC.
output of "hciconfig -a" (same with both PCs):

If I use scotest on the sending PC appears the following:
debian:/home/christian# ./scotest -s 00:07:80:81:A9:XX

on the receiving PC I get the following output:

the output of "hcidump -X -V for the sender:

it seems as if now and then the data is sent, but the only data I see on th=
e receiver with "hcidump -X -V is:

it seems as if the data that was sent is not received.
Do I maybe need a kernel patch like the "patch-2.6.18-mh8.gz" or is there a=
nother problem. I am stuck with this since two weeks and don't know what to=
do. But maybe that's because I started with Linux only 2 months ago^^. I w=
ould be glad if someone could help me with this.
Regards
Chris
