Hi All,

I have one question and one bug (? ) report

1. Question: in IOC Application Deveoper's Guide (Rel 3.13.0.beta4) 
  wrote about I/O Event Scanning, but on dbScan.c (useing SCAN_IO_EVENT)
  faild. 
  The reason is: piosl is initialized as NULL, and never updated. Where
  is my failure ?

2. Useing waveform record with a very slow hardware, I used double
  buffering and cahngeing the buffer pointer when the data is ready.
  On medm display I have seen only every second buffer. In an other 
  situation (also with the modified bptr) the old medm display displays
  wrong data but if I restart or starting a new, the correct data is 
  comeing. useing buffer copy instaed of bptr changeing helps, but 
  it costs memory and cpu time... 
  any idea ?
