Hi, As I understand, the IEC958 frame incorporates not only sound sample but also other information such as user data and channel status. I could not locate in the CMIPCI driver where the user data or channel status is read/write from/to the device and where is it kept on DRAM. Many thanks. ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
