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. -- dwmw2
