Hello, it wanted to know how I can extract of a dates frame the values peaks according to an interval that I establish. For example if dates are: 1 23 2 4 3 56 4 7 5 99 6 33 extract the date i wanted to divide into intervals of 2 an d to take alone the numbers 23, 56 and 99 of those 3 intervals. Thanks Ruben

Accessing the parallel port through wine is extremly inefficient: I have heard of people with 2 Ghz CPUs were the speed of the parallel port was still a lot slower than on windows. I have tried on an old Pentium 233 MMX and an AMD K6-2+ 500. Parallel port access is slow, CPU usage is at 100%. Parallel port access speed scales with CPU speed. I'm using the parallel port for an EPROM burner.
