Whether it is possible

Question

Let us say an engine is interfaced with computer. I wish to know whether it is possible write a program in C# to read engine speed, water flow rate and fuel flow rate. Let us say all these three parameters from engine have been converted into digital signal.

Long ago I wrote a program in Turbo Pascal to measure these engine parameters. Gide line was given in the manual came with the interface card (which converted engine parameters into digital signal)

If possible please write a sample program.
