unknown signs before each line of Gcode in nanodlp windows

testing nanodlp windows with ramps and arduino,
at the start, there are printed unknown sings before each line of gcode that echo returns: unknown command. also when i send "G28" or other gcodes, it behaves the same. what is the problem? please look at end lines in the link below:

Configuration seems correct. I guess parity and other serial related setting are not correct causing issue. There are lots of extra characters at the end of each command being send or received.
