I guess I should have read all the mail before asking my question.
Thanks, Dudley and Tom, for the tip on the USB ports.
On the other hand, there seem to be conflicting explanations and
experiences here: some people don't see the lag while others do, and
Carl says that the lag is not port speed dependent, implying that moving
to a USB port should not improve matters. In order to minimize the lag
problem in my shack, I am using a desense setting of 11 on the remote
pod, which helps somewhat. However, if I want to make a large change in
frequency, the pod moves too slowly, and I usually wind up using the
mouse and Fast A key on the display. Nevertheless, I have a spare USB
port and a serial adapter here. I'll try it and see what happens.
As far as my comments regarding the N4PY keyboard are concerned, I
should have said that I was using W98 on a 450 MHz machine at the time,
and that I was quite unfamiliar with the program and did not spend any
time trying to improve the keying. Perhaps if I had worked at it, the
problem might have been solved. I should also add that I minimize the
number of applications running, even on the 2.2 GHz machine, so that the
amount of CPU resources devoted to generating CW, transceiver needs, and
other ham software applications are maximized. The only problem I've
noted with the DX4WIN keyboard is that if I save the log while it's
sending, there might be a slight, one time momentary delay.

Tom has a good point, since I have been using a USB2.0 serial to USB
adapter, the lack has been non-existent. Right now I am running with
6 serial to USB adapters to my 1.8 ghz computer.

Just a small observation...the speed of the CPU has very little, if
anything to do with the speed of the serial port. If your need faster
I/O speeds, it's probably best to look at using USB 2.0 ports instead
of serial ports.

Jerome, I've observed this same problem with the O(rion control
software. It's sometimes difficult to fine tune a station because
one tends to overtune or overshoot the signal. Carl has said that
it's because of the speed bewteen the radio and the computer serial
port. I recently upgraded from a 450 MHz to a 2.2 GHz machine and
there was little, if any, improvement, suggesting that Carl's
assessment is probably accurate.

Hmmm... sounds like a computer rather than the control software
problem. I've used the Pegasus software on four different computers
from a P100 up to a P4/3gig machine and never noticed that kind of
a lag.
I have noticed, using Task Manager, that large frequency excursions
tend to be the most cpu resource intensive --
sometimes up to 80% for a split second, but I never could correlate
that with a visible/audible lag. It's interesting that HRD behaves
exactly the same with a large change in vfo frequency.
I would bet that a 486 might show the kind of behaviour you describe.

Hi Ron,
Unless you are using an Orion what you want is the Pegasus
software from
N4PY. I use it and it works fine with one exception. Because of a
port
speed issue tuning the radio lags the screen display on the computer.
However, if yu are into cw, the keyboard keying is great and also the
ability to scan a range of frequencies.
