Re: [PLUG] Dell Optiplex 745 video
If you/re anywhere near Vancouver I've got a DMS-59 to dual DVI cable P/N H9361 and a DMS-59 to dual VGA cable you can have.

The manual for your specific model is the ultimate authority, but I did find this for APC BE450G/550G models that mentions adjusting sensitivity without having to run their PowerChute software (windows only). I wasn't aware of it so I'm sharing with others who many not have read all their friendly manuals. Voltage Sensitivity Adjustment (optional) The Back-UPS detects and reacts to line voltage distortions by transferring to battery backup power to protect connected equipment. In situations where either the Back-UPS or the connected equipment is too sensitive for the input voltage level it is necessary to adjust the transfer voltage. 1. Connect the Back-UPS to a wall outlet. The Back-UPS will be in Standby mode, no indicators will be illuminated. 2. Press and hold the ON/OFF button for 10 seconds. The OnLine LED will illuminate alternately green-amber-red, to indicate that the Back-UPS is in Program mode. 3. The Power On/Replace Battery LED will flash either green, amber, or red to indicate the current sensitivity level. Refer to the table for an explanation of the transfer voltage sensitivity levels. 4. To select LOW sensitivity, press and hold the ON/OFF button until the LED flashes green. 5. To select MEDIUM sensitivity, press and hold the ON/OFF button until the LED flashes red. 6. To select HIGH sensitivity, press and hold the ON/OFF button until the LED flashes amber. 7. To exit Program mode wait five seconds and all LED indicators will extinguish. Program mode is no longer active. Also, startup current for a motor can cause quite a dip in line voltage. Anything longer than 1 cycle should be picked up by the UPS but you might not notice the flicker. Do you have a fridge and/or freezer?

And unless you have a reay good reason not to, use the same SSID and passphrase for all the routers/APs sharing the same subnet for simplicity's sake. Set each router/AP to a separate and fixed channel, one of 1, 6 or 11, instead of using the Auto setting. Hopefully there isn't a nearby router or RFI source on more than one channel. May require futzing with to find the best combination. NealS ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

So ideally the program you're talking to the port with would be the one setting the baud rate and bits so there's no chance for unintended consequences. I've lost track of how you're doing it. Ideas?

Only if you have a USB sniffer/protocol analyzer. There's a LOT of stuff going on at the bus level that would be way too much work to sort out without one.

If you're only running 600 baud it will be more than fast enough. All you need is a resistor or two to scale the input signal: https://rayshobby.net/reverse-engineer-wireless-temperature-humidity-rain-sensors-part-1/ Enjoy!

Re: [PLUG] com port in guest to usb in host (virtual box)
Denis, I believe "-parenb" means no parity, as shown in your stty -a output, looks good to me. I'm just guessing, not having anything serial or scope-ial to hook up to my linux box at the moment. The cooked/raw/echo/xyzzy settings are way beyond my scope of experience. NealS ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

I applaud your efforts in doing this Just Because, intellectual curiosity, comfort food for the programming soul, etc. Richard. Just Because I was curious I ran 'apt install basic256' and got this: 0 upgraded, 43 newly installed, 0 to remove and 11 not upgraded. Need to get 21.0 MB of archives. After this operation, 60.3 MB of additional disk space will be used. Do you want to continue? [Y/n] y Hmmm, pot, kettle corpulent is in the eye of the dependency, etc. :-) I'm no expert but several of the extras seem to be qt4 related. I don't grok qt4, just guessing based on console output. This was on a Ubuntu Server 16.04.1 LTS box used mostly for Samba and WeeWx purposes, with little else added from the base non-GUI install.

Re: [PLUG] com port in guest to usb in host (virtual box)
Is the USB-RS232 adapter known to work? Several years back I had a no-name adapter. Couldn't get it to work. Found out it had a fake Prolific chip in it. No wonder it had such an attractive price. Try looping it back to itself and see if it works before you go too far down a rabbit hole. Possible complications with modem control lines are beyond my Linux experience.

Re: [PLUG] Need to use DBus...
Ken's post reminded me of a thought I had on the subject. How about copy the print/plot/data file to the destination machine, and then create a separate link that the printing/plotting process actually looks for. That way no partial file exists at any point from the consumer perspective. NealS ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
