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