Hi all,

I'm trying to do something really simple in the bluetooth environment.
I attached a USB bluetooth module (from A7 engineering) to a Linx PC,
and I attached a serial module to a windows PC.  This serial module has
the complete stack, and I just interface to it with ASCII commands over
a serial port profile.  I want to simply send ASCII text across a
bluetooth serial connection between the two computers.

I have been able to do this successfully with a windows host.  Here are
the steps I'm taking:

*	On the Windows side, I connect to the serial bluetooth module,
configure the baud rate to 9600, no HW flow control, etc.
*	On the Linux side I start the hcid and sdpd services.
*	Then I search for the remote bluetooth device using "hcitool
inq" and I see it.
*	I establish a connection using "hcitool cc <bt address>".
*	Finally I use rfcomm to make a serial connection:  "rfcomm
connect 0 <bt address> 1".

The windows side recognizes a connection is made, but I am unable to get
data across.

I have found no way to establish baud rate.  Is that necessary across
bluetooth?  

I am expecting to just type into a window and see the characters show up
in the external window.  This works when both sides are Windows machines
using hyperterm.

Instead, when I type on the windows hyperterm, I get the ascii
characters repeated (is the Linux side bouncing the characters back?).
On the Linux side, when I type in the window, nothing really happens.

Any help/advice would be helpful.

Thanks in advance.
