Re: comport conflict

Many thanks guys
I have tried every combination of setups between N1mm, radio, COM 3 winkey and COM 6, the virtual COMport of the rs232 to usb lead and find that  by opening the device manager it can be seen that if the COM 6 lead is inserted first it shows on device manager, then when COM 3 lead is inserted, COM 6 is shunted off and only COM 3 shows, also chaos reigns, freezing ,etc. So com 3 always first.
This could explain why N1mm worked flawlessly in the IARU contest a while ago, and why it always worked well before, when I used a serial lead. I set up a contest on a dummy load and all ok, so  I’ll know on Saturday if this is the answer.
I use a half G5RV antenna with 100 watts max and  only use CW. I have never had  rfi issues
This begs the question why a good serial lead should fail and also a new replacement lead on both PC’s
Two duff leads is stretching it a bit but not impossible I suppose.  Do they need drivers ?
Also  I get a lot of background noise on 10 , 14, 24 , 28 Mhz which seem to increase when I plug in the RS232 lead. Is it coming from the radio into the PC and back thru winkey?
Would a toroidal ring wound into the  input coax be the answer or ferrite rings somewhere?
Thanks for  your advice, if things run smoothly in the SAC contest it may benefit someone on the forum.
I’ll let you know anyway.

You said "If another prog was running using com 5 would it not appear on device manager before I plugged in winkey and radio". No, device manager does not report whether an application program is using a port, it merely reports that the port exists in your system, regardless of whether it is currently in use or not. If some other program is using COM5 before N1MM+ starts up, N1MM+ will be unable to open COM5 and will tell you so at startup. If N1MM+ is able to open and use COM5, then there is no other program using it at that time.

If N1MM+ is able to open COM5 and use it to communicate with the radio initially, and subsequently it starts issuing error messages related to COM5, something is going seriously wrong inside the computer. If the start of the problems coincides with the beginning of transmitting, or perhaps with the beginning of transmitting on a particular band or a particular mode or with a particular antenna, that is a very strong clue as to the cause of the problems.

In your first message, you said, in part: "..."N1MM+ tunes all freqs, all bands ... When I start a contest and start to key, ..." and then problems start to happen. This is a classic description of an RFI problem. Peripheral devices (keyboards, mice, almost anything using USB) are particularly susceptible to RFI, and coupling of RF from a nearby transmitter onto the wires connecting these devices to the computer can introduce all sorts of spurious signals into the computer that can result in all kinds of crazy behaviour, including generating error messages that have nothing to do with the actual cause of the problem. Do the problems still happen if you reduce transmitted power to a very low level and/or use a dummy load?

Sorry, it's not a tuner, I mean the radio which is "tuned" by the digimaster.
Another message received is "This action cannot be completed because the other application is busy. Choose “switch to “ to activate the busy application and correct the problem
Switch to        retry"
This locks up everything and I have to switch off at the wall
It doesnt say what program it  is and pressing   switch to   or    reset
does nothing. This appears with N1MM classic which I've used for years and never a hitch.
The first sign of trouble was when the radio ceased communicating with  N1MM.   I was told it was probably the catlead altho why a good lead should rupture I don't know but I bought a new serial lead and that didn't work either so I got a serial to usb  Digimaster with an ftdi chip and that works fine, all freqs, all bands.
If another prog was running using com 5 would it not appear on device manager before I plugged in winkey and radio.
Using two PC's, com 3 always defaults to winkeyer  and the others are virtual comports from Digimaster.
This N1mmsocket 13064 seem to be a messaging device but in config-broadcast data nothing is ticked.
I tried tuning/testing the radio using a laptop with win 7 and that worked but I haven't tried it in a contest yet, and that's when it happens, although in the IARU contest it ran continuously.

Subject: [N1MM+] comport conflict
I think there may be an incorrect config entry in my program
. I only use CW with win XP, Winkeyer USB and Digimaster serial to USB using a virtual comport.
Displaying device manager shows ;
comport COM 1
Comport COM 2
printer port LPT 1
Plugging in Winkeyer - USB serial port com 4
Plugging in Digimaster - USB serial port COM 5
N1MM+ tunes all freqs, all bands and keys them.
When I start a contest and start to key, the tuner freezes and the following message appears-
"Receiving UDP N1MMsocket 13064 is already in use. COM 5 is in use by another program but the port is also configured in N1MM Logger.  The comport will not work in N1MM Logger until this is corrected"
My Config readings are
Com 5 FT 450 9600 n 8 2 DTR always on  RTS always on  1 radio polling rate normal  ticked
Com 4 CW tick DTR always on  RTS always off  VFO 1 ptt 30  Winkey ticked
Radio yaesu ft 450 catrate 9600 same as program
In config - broadcast data nothing is ticked.  Is it possible that a setting in digi or other section could be interfering with the CW ?
I had a similar problem on another PC
Would appreciate your advice.
