how to redirect vt100 input to stdout

dear Experts,

I want to transfer the vt100 input to the stdout console.In my application I recieve the vt100 compatible data along with escape sequence.I want to extract the information from it and tranfer it properly on the scree.If I use the printf function,cursor moves randomly and display is garbage.So it seems that cusors should according to the escape sequence.Would you please how to display vt100 to stdout ?
