In all likelihood, I will simply have to eschew using these control lines on this machine. Have you tried looking in Device Manager at the properties for the serial port?

You need to login in as administrator then you will have full access or somehow your anti-virus/security software has locked you out. That ought to be fun to find.

And there is no replacement serial driver. Googling various combinations of key words turns up nothing related to this bug. Apparently this Dell RS-232 design error is so arcane relative to what virtually all laptop users use their computers for, that nobody has ever complained about it. :-) My last step is to go into the BIOS and see if there are any controls in there that live below the level of the OS. Oh well.

Re: [Elecraft] [K3] Serial port RTS problem [was: Different mode]
Bill, even if you make BIOS changes to a port it won't affect the port's operation under Windoze, since it's all controlled by a kernel mode driver. matt W6NIA On Sun, 27 Sep 2009 11:18:17 -0600, you wrote: Julian, G4ILO wrote: Have you tried looking in Device Manager at the properties for the serial port?

Re: [Elecraft] [K3] Serial port RTS problem [was: Different mode]
Thanks for that info, Matt. Did not know that. No controls in the BIOS anyway. I'll just have to live with it I guess. Fortunately, I can use VOX for TX control and don't really need to use the RS-232 control signals.

Julian, G4ILO wrote: I have never used VOX. Why would you need to? If you have a fully wired serial cable between the K3 and PC then just set WSJT to use that COM port and in the K3 menu configure PTT to use RTS. Julian et al., I have always used VOX for WSJT keying, so I tried setting it up for RTS control as you suggest above. But when I try to configure the K3 for ether PTT=RTS or PTT=DTR with NO RS232-controlling application (like WSJT) running, the rig keys up (and switches into TEST mode automatically as per the manual). If I then disconnect the serial cable at the laptop serial connector, the keyed condition disappears. My conclusion is that the laptop's serial port is asserting RTS and DTR full-time for some reason. It's a 2-year-old Dell Latitude D820, Core2 processor, 2 GHz, 2 GB RAM, running XP Home. It has one true RS232 port (COM1), the one I'm using. Flow control is set to NONE, so it should not be asserting these lines by default. Has anyone ever encountered this?

Re: [Elecraft] [K3] Serial port RTS problem [was: Different mode]
It may be a too obvious comment, but the easiest way to tell what is going on is with a serial breakout box. If you get one with LEDs you can visually watch the status of the control and data lines in real time.
