      <div>TTY was derived from Teletypewriter - a device originally
        used by people who are deaf to communicate.  But today
        Teletypewriters no longer exist and TTY is used to refer to a
        type of telecommunications device used by people who are deaf
        that supports Baudot (and sometimes other coding schemes) over
        analog phone lines. </div>
      <div><br>
      </div>
      <div>that however is probably too much history.     but if you are
        using Teletypewriter - that would be the \correct way to use it.</div>

    I do not see TTY as an acronym anymore.<br>
    <br>
    It is like BT that was read out British Telecom before, but is now
    just BT.<br>
    <br>
    Or AT&T was read out American Telephone and Telegraph, but is
    now just AT&T <br>
    <br>
    Wiktionary has solved it by putting (originally) after
    Teletypewriter.   <a href="http://en.wiktionary.org/wiki/TTY">http://en.wiktionary.org/wiki/TTY</a><br>
    <br>
    Following that pattern it can be:<br>
    <br>
    TTY (Teletypewriter (originally)) and other text telephones<br>
