Serial data parsing may occasionally go wrong？

[marseric]

This is really a very good project, I like it very much, thank you
But it seems Serial data parsing may occasionally go wrong？
For example, when I send 2 floats and 1 integer together：
printf("$%5.2f %5.2f %d;",ftemp1,ftemp2,int1);
It sometimes shows 4 or 5 curves at the same time.
Any suggestions? Thank you
