Barry, I think we've already forgotten what Wayne posted just 4 days ago.
Get a WKUSB, you wont be sorry, it works better, allows for paddle input
interruption of the CW string, doesn't jitter, can be used for remote, is
fully supported, is cheap, is fun to build, etc.. anyway here it is again:

Yes, you'll need something. WriteLog has supported sending CW on the RTS
line of an RS-232 interface since its very early versions in the late 80's.
But.....
I really don't like trying to support that any more. Sending CW that way
requires the OS to give WriteLog response times on the order of
1 msec, else your CW will be garbled. All Windows versions are actually
capable of this, but most of us have all kinds of "stuff" installed on our
machines now taking up cycles, so I would trust only the most PC savvy (or
those running the oldest machines with their original OS installed) to be
sure they actually have found and disabled all the drivers, virus checkers,
malware, browser plug-in's, etc. etc. etc. that compete for CPU cycles just
at the critical time that turns a dit into a dah. You might be surprised at
what kind of supposedly useful software can do this (network drivers, IDE
CDROM drivers, USB hub drivers, virus checkers, etc. etc. etc.)
There are a number of devices on the market that can do this (google
"winkey" for example). We used to sell one just for WriteLog, but the
MK-1100 is out of production now.
