Hi Manjunath,

the link manager has a list of packet types it is able to use and it
will use them. There exists a command to change the packet types of an
already created connection and this command will also create an event
that informs you that the packet types have changed. Besides this you
can only guess from the size of ACL data packets what packet type the
link manager is using and this is not an exact science.

No, because DM1 is always allowed.
