    Answers:

    If you can figure out how to send characters to the device at all , it's easy enough to send escape sequences. In ASCII, the ESC code is 033 (27 decimal), so code like
    fprintf(ofd, "33[J");
    sends the sequence ESC [ J .
    Some programmers prefer to parameterize the ESC code, like this:
    #define ESC 033
    fprintf(ofd, "%c[J", ESC);
