** Parameters: scn - Service Channel Number as registered with
** the SDP (server) or obtained using SDP from
** the peer device (client).
** is_server - TRUE if requesting application is a server
** mtu - Maximum frame size the application can accept
** bd_addr - BD_ADDR of the peer (client)
** mask - specifies events to be enabled. A value
** of zero disables all events.
** p_handle - OUT pointer to the handle.

** connection up/down events.
** Notes:
**
** Server can call this function with the same scn parameter multiple times if
** it is ready to accept multiple simulteneous connections.
**
** DLCI for the connection is (scn * 2 + 1) if client originates connection on
