     305The argument <font color=red>name</font> may contain path information in addition

     336Defines whether wave_serverV should purge all asynchronous trace buffer  
     337packet data on startup. If the argument <font color=red>U</font> = 1 then the 
     338packet data is deleted on startup. If it is 0 then packet data is not purged on  
     339startup. Note that packet data is purged periodically during the operation of

     292Wave_serverV can now be configured to deal with asynchronous data. Data packets that  
     293overlap in the data stream can be buffered to a database file. As data is supplied to  
     294client applications this data can be resynchronized into the stream. There are a few configuration  
     295commands that can be used to control this behavior. To turn on this processing set  
     296<A HREF="../cmd/wave_serverV_cmd.html#UsePacketSyncDb">UsePacketSyncDb</A> to 1. The 
     297database name defaults to TB2PACKETS.SL3DB but path and filename may be specified with the 
     298<A HREF="../cmd/wave_serverV_cmd.html#PacketSyncDbFile">PacketSyncDbFile</A> setting. The  
     299packet database is purged occasionally during runtime, deleting any packets older than  
     300the oldest packet in the tanks. The <A HREF="../cmd/wave_serverV_cmd.html#PurgePacketSyncDb">PurgePacketSyncDb</A> 
     301may be used to tell wave_serverV to purge the database on startup. These settings may be 
     302modified in the configuration file followed by restarting wave_serverV.
