Re: [Wlug] monitoring a Matrix 3000

by Bill Mills-Curran

Karl, I've done the testing you suggested... I hooked up a null modem cable to another linux box that was configured to allow serial port logins. After using minicom to configure the port (9600 bps), I was able to log in. I could also exit minicom and, using 2 terminal windows: term 1: cat > /dev/ttyS0 term 2: cat /dev/ttys0 I was able to get the login and password prompts with the above, so I have some indication that the serial port is working, although I don't know if it's right for the UPS. My next test is to scrounge a signal analyzer (and someone who knows how to use it) to see if the upsd daemon is sending signals out the port. more below...

Bill, I've had problems with serial ports in the past. Usually a really dumb reasion for it not working. Verify the BIOS has the port turned on. With the default IO address and IRQ settings. Does a mouse work on the port? If you have a null modem cable. (Switches RX and TX lines) you can hook two computers together. Run terminal programs on each (with the same baud rate settings, no flow control). You should be able to type chars between the two boxes. Have minicom installed? can it open the port without an error? If you don't have a null modem cable/connector you can pick them up at most radio shacks. Or you could try communicating with an external modem. Running a redhat default kernel? Should work fine. If you compiled your own make sure you have the serial port setup correctly in your kernel config. Try chmod 666 /dev/ttyS0 Serial HOWTO: http://tldp.org/HOWTO/Serial-HOWTO.html Serial Laplink howto: http://tldp.org/HOWTO/Serial-Laplink-HOWTO/index.html Have a DOS bootdisk? You could try running an old skool terminal program like procomm or something like that. Or hypertermainal in M$ Windowz. Good luck.

Re: [Wlug] Multiple mice on a laptop

by Nate Godin

Hmm... I did this a while back, setting up a serial trackball in addition to my PS2 mouse on my desktop... you have to load a the XInput module, and do some XF86Config tweaking... I don't have the config file I used anymore, but I recall figuring out how to do it by reading the XF86Config man page... here's an example... Here is an example of a ServerLayout section for a dual headed configuration with two mice: Section "ServerLayout" Identifier "Layout 1" Screen "MGA 1" Screen "MGA 2" RightOf "MGA 1" InputDevice "Keyboard 1" "CoreKeyboard" InputDevice "Mouse 1" "CorePointer" InputDevice "Mouse 2" "SendCoreEvents" Option "BlankTime" "5" EndSection My G4 Powerbook actually seems to be able to do this automatically, I'll go boot that over to Linux and post the XF86Config file...

Multiple mice on a laptop

by Adam Elliott

Hello, I've got a laptop that usually resides in a docking station at work, where it is connected to an ordinary wheelmouse. That works fine. When I take the laptop out of the docking station, disconnect the mouse, and start up Linux again (so using the touchpad), the pointer tends to go crazy. Now, I know the reason for this is the protocol is wrong in the XF86Config file. The wheelmouse uses IMPS/2 with 5 buttons (3+wheel), the touchpad PS/2 with 2 buttons. I can fix this by editing the XF86Config file appropriately, and the touchpad works fine. Now, my question is: Is there any way to get Linux to automatically figure out that the mouse is not attached, and so fall back on the touchpad? BTW, I've set up two "Pointer" sections in XF86Config, and just adjust the CorePointer line to reference the correct one. XFree doesn't like having two CorePointers. I'm using SuSE 7.3, XFree86 4.x if it matters. Thanks, -Adam

Re: [Wlug] monitoring a Matrix 3000

Karl, I agree that the serial port is the prime suspect. (I'm working the serial port test you suggested) Can you give any hints as to what might need to be configured? Note that this is a new installation, and I've done nothing to set up the port. Any suggestions what configuration changes or module loads I might need to enable traffic on ttyS0 and ttyS1?
