Tell it the people who force me to use it. ;-)
BTW: The Windows kernel debugger works this way, even with 115200 bps,
and it is really reliable.

Yes, I know. Although I am not an electrician, I have a basic
understanding of electronics, having started with this before I got into
the "computer business" (does anyone here in germany remember these
"Kosmos Elektronik" parts? ;-))

No, I've never seen one of these. But *now* I know why the IEC port of
the C64 had a diode - mine did not, and this was really fun whenever the
floppy was not powered and you powered the monitor on or off, or someone
was powering a light bulb in the near... :-(

I know, and the people who did it there knew it, too. Anyway, it
happened nonetheless.

Same as above.

No problem, this is what I'm using currently (no, not for my C64).

Yes, I know.
