Thanks for the input, Mike. It was VERY relevant!
Based on Mike's suggestion, I disabled rig control (No Rig in all serial
port slots) and set the frequency and mode manually. With that setup, the
Belkin F5U409 SENT SERIAL PORT DTR CW PERFECTLY, either from the Alt-k
dialog box or from the F key memories.
That is a very important result, since it shows that of the two problems
that I originally described (no rig control and no DTR CW), the CW problem
is nothing but a direct consequence of the rig control problem. Now that
serial port DTR CW is solved, I will try to focus on why rig control doesn't
work.
I don't use a rig interface box, since Yaesu FT1kMP has a true RS-232 serial
port on the back. There is a Maxim MAX232CWE chip on the control PCB in the
FT1kMP, so the signal levels on TxD and RxD are perfectly compatible with
PCB serial ports.
Thanks again for the tip, Mike. That's just the kind of information that
makes working with a large and knowledgeable user group successful.
73, Jim, W8WTS.

One thing that I have noticed is that WriteLog memories via the F keys are
dependent on the mode read from the rig. If the mode is not CW, the Fx keys
don't work. That is true for RTTY also.
What type of rig interface are you using? I have found that W1GEE
interfaces don't work with USB cables that use the Prolific PL-2302 chips.
Must have something to do with deriving power from the serial port, but I
never did look real close at it. A standard Kenwood IF-232 has no problem
with it. These chips also don't do FSK RTTY properly. I have found them
used in the RocketPort II and USBGear dongle cables.
I have a Silicon Labs CP2102 development board coming in a few days that,
from the data sheet, might be programmed to work properly.
You might be better off getting one of the USB rig interface boxes.
They are more expensive, but at least they are designed to work with
WriteLog and the various rigs.
