+ * The very first cutom AT command has no peer. So find it by broadcasting the command
+ * over all BAT sources. A BAT source is associated with a DTI connection between PSI
+ * and ACI. A DTI connection is associated with a certain BAT Lib instance. A BAT Lib
+ * instance can be created by a third party application suite, by Bluetooth, by TCP/IP
+ * its bearer manager BEAM and others in future.
+ * After sending the very first custom command over BAT via broadcast, we wait for the
+ * very first answer. Then we know our peer and will address it directly with all 
+ * following custom commands.
+ * The following simplified MSC illustrates this.
+ * The BAT["XXX"] shall express that the string "XXX" is content of the BAT custom container.
+ * In the MSC at sequence 8 we got an answer to the custom command. Here we know our peer.
+ * Sequence 11 is neccessary to make the state machine of BAT LIB happy.
