How to calculate checksum for frame?
For instance, we have this frame: 7E A0 0A 00 02 00 23 21 93 18 71 7E
18 71 - Checksum of this frame. But how was it calculated?
I think it calculated for this part of frame: A0 0A 00 02 00 23 21 93
But how? I tried few calculators and some codes but it didn't work...
Maybe there is some table for this...
I tried find it in the .NET gurux library, but i don't now what name of it.
