   public abstract Writer startJob(String dsname)  throws IOException

This method is called for each output job. It must be callable from multiple Threads - synchronizing the implementation is an easy way to do this.

Returns:

an open Writer for the output, or null if this SNADevice is busy and another should be selected to handle the input,

   public abstract void finishJob(Writer wtr)  throws IOException

This method is called when a job is completed normally. If the Writer is closed without finishing, it is effectively aborted.

   public abstract int getMedium() 

Return the medium and subaddress handled by this SNADevice. If the subaddress if FMH_1.FM_ANY, this device will be used for any subaddress.
