I'm
sure i'm off base here as I'm not in the same league on this stuff as
most. But I recall an issue with the StepIR box that the external program
being used need to poll the radio to get the propper commands sent and picked up
by the stepir interface. If there is nothing polling the SDR or making the
SDR send the sigs thru the com port then the stepir won't know anything has
changed. So either the radio has to poll automatically to a specified com
port or another program has to make it poll.
OK....now I've lost myself. Take a poll......who thinks i've gone
over the edge? DON'T ANSWER THAT!

Bob and
Bill:
I have a few more clues on the SteppIR / SDR1000
interface issue. First of all, Bob, the zero fill is ok. I
confirmed in my Kenwood TS-450S manual that any fill character except a
semicolon is legitimate at least for this transceiver. I have an old
TRS80-100 that I programmed up as a Kenwood simulator, and confirmed
this.
I had a level problem between the SteppIR box and the SDR1000
computer that I solved which allowed me to view the following:
1) The SDR will change the SteppIR box one time only when you open the
application.
2) If you change the frequency while the
SDR application is open, the SteppIR box will NOT follow.
3) If you change the frequency, close the application completely and
reopen it the SteppIR box will go to the new frequency but again only that one
time.
4) This is consistent with the portmon.log file
which shows this to be the case.
That is about all that I know how to
do. I have a feeling that this bug might spill over into other
applications besides the SteppIR app.
I hope this has been helpful and
thank you for your time.

Tom,
If the SteppIR is looking for spaces as padding for the frequency, then we
have a real problem. The Kenwood spec (used to develop the SDR-1000 CAT
parser) specifically requires any blank character in a frequency string to
be "0".
Let me know what you find.

Bill,
After looking at the portcom.log file this morning, it looks as if the
IF; command is getting through every time but a response is only being
generated once. That response is a little different from the one that
actually drives the StrppIR box correctly in that it has zeros in place
of spaces. I don't know whether this makes a difference or not, but I
will pursue it and let you know.

The CAT comm port code should work with a physical port, at least it
did at one point. Has been a while since I've run it in that mode.
Do the SteppIR docs on using a CAT controlled radio say anything about
flow control settings? I don't recall what flowcontrol we set on the
port when we open it, I do see that we don't provide a way to set it
(argh).
The error you sent me in a private email makes it look a little like
we failed to open the comm port - it seems we're attempting to close
an already closed port and I know I've seen the code get into that
error path when we failed on the initial open of the port. Is there
any chance there's another program using COM1 -- maybe a PDA sync
program or some such. Also check that the CW keyer is not set to use
COM1.
Next step is for you to download and install Portmon from
http://www.sysinternals.com/Utilities/Portmon.html and trace the
failing scenario and send me the resulting trace file. That should
give me some idea what is going in.

Tom,
Bill (KD5TFD) knows more about the serial port code than I do, maybe
he will
chime in with a real answer about whether or not it can be used in real
mode. I have no means of testing it other than with my SDR-1000.
Looking
at the code, I can't see any reason for it not to work in real mode.
Meanwhile, the CAT tester does not interface with the serial port, it
interacts with the console software directly so it is no indication
that the
port is working. Secondly, you might try changing your ID selection
on the
CAT tab to something other than "SDR-1000". I suspect the StepIR
software
doesn't know anything about an SDR-1000. Try one of the Kenwood models.

Subject: [Flexradio] CAT Control
I want to have my SteppIR follow the frequency changes on my SDR-1000.
The SteppIR sends an IF; command in the Kenwood command set every
second. I have configured the CAT Control for COM 1, 4800 baud, no
parity, 8 data bits, and 1 stop bit. The ID is TS-2000 and the IF;
command produces the correct response in the test mode. Hyperterminal
is seeing the IF; command from the SteppIR box, but there is no response
from the SDR when I enable it. Are the COM ports on the CAT Control
real or just virtual.? If just virtual, what do I do to get the CAT
Control to connect to the real COM 1?
Thanks, Tom W0IVJ
