I did look at the manual page, but all I found was:

lst <bdaddr> [value]
              With no value, displays link supervision timeout for the
	      connection to the device with Bluetooth address bdaddr.  If  value
              is given,  sets the link supervision timeout for that
              connection to value slots, or to infinite if value is 0.

But this only sets the timeout for conncetions which are already
established. I would like to change the timeout for trying to establish a
conncetion, e.g. if the device can't be found within 2 sec. stop trying.

Cheers,
Phil
