in RTE protocol exit is not happening giving timeout error

through script I wrote a code :

below I am unable to exit from putty gives 90 timeout error, cursor blink till "sometext>" I expect exit should type here from below bottom lines

TE_type("g.ack<kReturn>");
    TE_wait_text("sometext>", 90,1,yStartPos+1,80,600,&xStartPos,&yStartPos);
    TE_wait_sync();
    lr_output_message("=================%d",yStartPos);

    TE_get_text_line(1,yStartPos-1,-1,text);
    //lr_output_message("=========##===%s",text);

        while(row<yStartPos)   //row=1
            {
                TE_get_text_line(1,row,-1,text);
                lr_output_message("##########%s",text);
                row++;
            }

    TE_type("exit<kReturn>");  //exit is not typing after exiting loop
    TE_type("exit<kReturn>");
