Hi,

I'm trying to work with the Data Translation DT2821 in streaming AD mode.
For a first test I tried the cmd example from comedilib. That seems to work,
but  there are two problems:

a) For larger scan counts, every 16th block the cmd example prints out
contains only "0"s instead of the sample values.

b) At least for higher sample rates (>= 10kHz) the system crashs after a few
blocks.

I'm using SuSE Linux 8.1 Pro with Kernel 2.4.20 + RTAI 24.1.11. comedi and
comedilib cvs snapshot (30.8.2003).

It would be nice, if any one could help me - thanks in advance

Carsten
