Well ... it will always be RS-232 in my old decrepit mind - at least I
know that I will be understood when I say RS-232.<br>
<br>
I think this falls in the same category as us hams operating CW with
our telegraph keys. <br>
<br>
<ol>
<li>It has always bothered me a little that Morse code is called CW
(Continuous Wave), when it is actually about the most NON continuous
wave I know of. </li>
<li>Of course, with CW we are referring to the characteristic of the
key down signal when no information is being transmitted. </li>
<li>However, based on that definition, AM, FM, and RTTY should all be
called CW as well. In fact, those are really the true CW modes,
because they use a 100% key down carrier, a real continuous wave,
whether they are transmitting any information or not.</li>
</ol>
