  5. HISTORY
    
     Version 1.0.2
     -------------

     August 01, 2001 -- First customer ship

     o Added a read notification check to PortSetReadCallback
     o Added open, close and transmit timeouts to avoid locking 
       the system when affected by a hardware conflict with the 
       Viper driver
     o Implemented the low latency feature
     o Changed the low latency feature user interface from a 
       checkbox to a drop-down menu and moved to global options
     o Implemented a selective transmission pause to prevent 
       the print driver from corrupting the data stream
     o Modified the configuration handler to assign interrupt 
       request (IRQ) resources to the board's ports to coerce
       Serenum to poll for Plug and Play modems on boot
     o Implemented a sync delay when asked to drop DTR to 
       prevent the print driver from truncating the data stream
     o Implemented a workaround to the shutdown stall failure
       by modifying the polling thread to check the system 
       initialization state during each poll iteration
