Right Click on This PC or My Comptuter or whatever it is called on your
desktop. Click on Properties, Select Device Manager
Double Click on PORTS
Look at the list of COM ports used
Double click on the one you think you are using
Click on Port Settings
Make sure these are all the same as you have your radio setup to use.
Then, there is one more thing hidden here.... if you think COM3 or COM4
could be used by something else, click on Advanced and change the COM
port to anything else that did not appear in the original list (ie, an
unused COM port).
Close everything and reboot the computer. (Not really necessary to
reboot but windows does weird things sometimes and this is the safest
way to know if it works or not).

One more update - this is what it says in my manual - The FT450 D has
a built-in level converter, allowing direct connection from the rear
panel CAT jack to the serial port of your computer without the need of
any external boxes. You will need a serial cable for connection to the
RS-232C (serial or COM port) connector on your computer. Purchase a
standard serial cable (not the so-called null modem type) ensuring it
has the correct gender and number of pins (some serial COM port
connectors use a 9-pin rather than 25-pin configuration). If your
computer uses a custom connector you may have to construct the cable.
in this case, refer to the technical documentation supplied with your
computer for correct data connection. ----- The reason I am trying to
get the cat cable to work is that all rare DX now uses fox/hound to
operate digital modes and without a cat cable I am unable to work any
DX. Considering DXing was why I got into the hobby, that is why I am
trying so hard to make this work.

Updated message on the com port issue. Ok, so I went back to the
original usb to db9 serial cable and plugged it in. On Windows
Device Manager, there is NO com4 port showing a Prolific device.
So I unplugged it and plugged in the NEW cable I got through
Amazon. In Windows Device Manager it shows Prolific com 3 and
Prolific on com 4. Com 3 is the line to the NOMIC. Com 4 should be
the CAT CABLE from the Yaesu 450d to the computer. I am using PCC
450d software as stated earlier. When I open the software I first
have to select the com. Com 4 is in red and is the ONLY com port
showing in red. I click on it and it takes. Then I have to click
on a com button so it will connect to the port. It always fails. I
did install the driver that came with the cable I bought. It says
Prolific USB to Serial Comm Port 4 on device manager (and the
other on com 3). I don't think I have the tools to measure
continuity on pins. Could I have a bad RS232 port on the Yaesu? I
think the problem is in the computer somewhere. Why would a device
show up in device manager for one cable and not the other? And if
the device is showing on com 4 in device manager, I am wondering
why I cannot connect. I don't know if I can attach files here, so
I will explain the two graphics and the messages I get - select
com 4, enter, then click on com and get "connecting the com port
now" and this is always followed by "failed to connect the com
port." Is my computer damaged inside? Hope this update helps. I
really can't afford a new computer desktop right now.

I am trying to get my Yaesu 450d to work with a Cat Cable to
the usb port on the computer. When I plug in the cable I hear
clicks on the radio and the TX is flashing. But when I try to
use the PCC 450d software I set the com port to 4 and then
click on com. It tries to connect, but then always tells me
there is an error connecting to the com port. It shows com 4
as red saying that is the one to use. Com 3 is already in use.
I guess I need someone who could physically come look at the
computer or at the least get with me on team viewer. Com 3 is
being used for the Nomic serial cable. I can be contacted here
or call me at 713-305-2148. I really would like to be able to
control the Yaesu RIG from the software. Folks on the internet
said I probably bought the wrong cable. I disagree but I need
help. Thanks. Marty, AG5T
