The UART speed could be a problem on the client side too. Many CF cards
I've seen are pointlessly crippled and run at 115200 baud, instead of
about ten times faster as they should do.

The sensible ones which run faster will often do so just by tweaking the
input clock to the 16550 UART, so that it runs faster while it _thinks_
it's running at 115200 baud. Use 'pskey' to check what speed the
Bluetooth chip actually thinks it's running at.

Marcel -- it'd be useful if your hardware list would include the maximum
speed, btw.
