How to remove serial port driver

Hi,
I am developing test driver for serial port. I can't able to remove existing driver (su) from solaris 8.
I tried "rem_drv su" and rebooted system. system does not came up again and generates panic (core dump). Could anybody help me regarding this problem.
Thanks in advance,

Instrument drivers are in the "LabVIEW\instr.lib" folder. Each driver should be in its own folder. To delete it, just delete the folder. You may need to update the palette menu to reflect the removal of the directory.
Also, what do you mean by NI installing the driver? Are you referring to using the Help -> Find Instrument Driver? If so, what did you enter in the search criteria? Leybold isn't even in the list of manufacturers.

Missing PCI serial port driver on elitebook 2560p after faulty motherboard replacement

Hi,
I have the following issue, after a faulty motherboard replacement on my elitebook 2560p with Win XP, I find a question mark in the device manager list reporting that a PCI serial port driver is missing.
Browsing device properties I can read:
PCI serial port - PCI bus 0, device 22, function 3
and
PCI\VEN_8086&DEV_1C3D&SUBSYS_162B103C&REV_04\3&B1BFB68&0&B3
I've already tried locating driver without success in SP38312, SP45131, SP53918, unzipping the files and trying to locate manually the driver inside the folders with the windows driver update function.
can you help locating the correct driver?
thanks a lot in advance

How to remove a mapped drive

Hi all,
i created a mapping in my iMac pointing to a folder on my notebook with windows.
When I start Parallels to run a Windows VM and my notebook is not connected to the lan, the system stays popping up a message saying "The connection fails, maybe the server Notebook doesn't exists or blablabla...".
I would like to know how to remove this mapping because it doesn't appear on my Mac Desktop if my notebbok is connected to the lan, but when using Parallels, is almost impossible to work with the message popping up all the time.
TIA,
Alano.

The drive doesn't appear on the list...
That's the problem...I don't know where should I go to exclude this configuration...

How to remove a mounted drive at startup in a mobile account, using netinfo

How does one remove an mounted drive at startup in a mobile account, using netinfo?
One of the user automatically mounts a network drive on her new intel Macbook in her portable account. Trouble is that the network drive is only available on the intranet. So when she is on the road, it take the Macbook very long 3-4 minutes before it let's her log in.
Simply I thought to remove the drive on her macbook through the system preferences -> account -> login items. However the "login Item" GUI is very slow to respond and if it respond it does not let me remove the network drive. I tried this both on the intranet and off the network.
I tried to remove the mounted drive at start up through the workgroup manager, but it does not show up there.
So I thought that I try to use netinfo on the local machine. But I can't find where mounting info is stored in a mobile account. I thought it would be in the local @ localhost or should I connect to an other DB?

The login items are not stored in Netinfo, they are stored in loginwindow.plist in the users Library/Preferences. You can either remove the entries for the server or simply trash that file and let a default one get recreated.

Can't use ch340g serial port driver since upgrading to Yosemite on MacBook air

I use my MacBook air with the Arduino 1.0.6 IDE. Since upgrading ( free upgrade) to Yosemite. I can no longer acess the ch340g serial port. (does not show up in arduino ide). I tried re-installing the driver. I get no errors and am told the install was successful. This was working very nicely before the upgrade. I now have three boards I cannot use. I am at a loss as to what I should do. I suppose I could go back to Maverick but then I would have to go buy the operating system. This seems wrong to me. I was offered an upgrade that then leaves me up the creek without a paddle. Any help given would be highly appreciated.

I have the same problem, a non stable CM341 serial to tty driver on Yosemity on a MacbookPro Retina.
I followed the advice of Rsattaur, I executed the command: sudo nvram boot-args="kext-dev-mode=1" and now I have big problems with my USB-ports.
The result is a screen-of-death after connecting anything to my USB-ports!!!!

How to access serial port using servlet

I want to communicate with a microcontroller connected to the serial port of my computer.
*I am using the following:
Windows 98 operating system
Tomcat web server 4.1
*The directory structure is as given:
Tomcat 4.1/webapps/myjsp/web-inf/classes/remoteservlets.
I have placed my jsp files in my jsp folder and classfiles in remote servlets folder.
**my java program has compiled correctly.**
** my simple java application which accesses the serial port works fine.***
*when I start tomcat I am able to access the sevlet as the servlet responds with the button name i have pressed.
**** I have also tried the following
Copied file comm.jar in <JAVA_HOME>\jre\lib\ext
Copied file javax.comm.properties in <JAVA_HOME>\jre\lib
Copied file win32com.dll in <JAVA_HOME>\lib and also in c:\windows\system32 and c:\windows\system
***************which helped me do away with errors.
still I don't get any output. I dont get any errors either.
PLEASE HELP. URGENT. i am at my wits end.
Thank you.

Servlet is the one which runs in the server side...if u want to comunicate with the serial port of the server in which ur servlet is running can be done but making use of Communication api available....
U can download the Api from http://java.sun.com/products/javacomm/index.jsp
There are three levels of classes in the Java communications API:
High-level classes like CommPortIdentifier and CommPort manage access and ownership of communication ports.
Low-level classes like SerialPort and ParallelPort provide an interface to physical communications ports. The current release of the Java communications API enables access to serial (RS-232) and parallel (IEEE 1284) ports.
Driver-level classes provide an interface between the low-level classes and the underlying operating system. Driver-level classes are part of the implementation but not the Java communications API. They should not be used by application programmers.

[865PE/G Neo2 Series] How to correct "Parallel port driver service failed to start"?

I recently disabled the parallel port in the BIOS (I wasn't using it anyway) to try and free up an IRQ or some system resources, when I installed a firewire controller (which I wanted to have its own IRQ if possible). Then I periodically started getting this error "The Parallel port driver service failed to start due to the following error:
The service cannot be started, either because it is disabled or because it has no enabled devices associated with it." I Googled this, but any info I found either was not applicable or was in incomprehensible techspeak. I couldn't figure out how to prevent the error from occurring, so for the time being I re-enabled the parallel port in the BIOS--disabling it didn't free up any IRQ's anyway. I would like to know more about this, however. Is there a proper way to go about disabling the parallel port so that this error does not occur?
Should it be done before installing Windows? What are the advantages and disadvantages of disabling the parallel port, other than freeing up IRQ's (as I said, it didn't--unless this also happens only upon Windows install?). Gurus, please respond!

That was the first thing I tried. There is nothing called "parallel port service", nor is there any mention of the parallel port in any of the services listed. I don't know if it is even using any system resources, anyway. The ECP Printer Port always had a box checked that said "never use an interrupt" anyway. It has no conflicts or sharing. Maybe I should leave it alone. It's just that people always mention disabling it in order to free resources.

How to empty Serial port buffer ???

Hi!
I am having problems with serial port. I want to clear i
serial ports buffer, but i dont know how to do this. I am receiving NMEA data through that port and every now and then i need to clear it because there are too much data and i dont need them all. Could someone please help me?

Hi,
Take a look at this link.
http://www.sc-systems.com/JavaDoc/Serialio.SerOutputStream.html
flush
public void flush() throws IOException
Causes any buffered data on the output stream to be written. Note: when using txDrain be advised that some OS's (like WinNT) do not provide a timeout on the OS level drain/flush call. In this case if handshake (flow control) is disabled from the far end your txDrain call will block until drain can complete. (i.e. until the handshake state changes). Because of this the default mechanism for flush is to watch the txBuffer. This will allow you to abort a stalled OutputStream since your code will not be locked up at the native level.
Throws: IOException
if an error occurs. Overrides:
flush in class OutputStream
However the above function and the class defining this is not provided by SUN.
I hope this helped.

How to abort serial port VISA from wating.

Hello All
How can I abort serial port VISA while wating for a byte to arrive.
Lets say I have timeout set for 3 min. but I want to cancel it before that , how to do it programatically?
I tried to set timeout to 0 while wating for data, and it works, but I do not like this method.
Thanks in advance
Pawel

Hi again
I have made some investigations, and here is what I found:
None of Serial Port Brake nor Set Time out work while the "VISA read" is active. All property node can access VISA class only when the "VISA read" is finished.
Therefore, it looks like there is nothing I can do when VISA is active. The only solution is not to allow VISA read.vi to activate. I think I can use your idea and monitor the amount of bytes at the port.
I wanted to avoid it.
Thank you for your help

How to read serial port only when new data has been sent to it

I've written this very simple vi to read the serial port whenever the MKS Helium Detector sends a new value. The timing of new data is controlled directly from the front panel of the MKS instrument. I thought it was as simple as looking at the "bytes at port", and reading the port only if the value is not zero. The problem I'm having is that the read function is occuring whether I want it to or not. Consequently, the "Scan from String" function is returning an error (0) once in a while, because it's reading the serial port as it's being updated (I think). Apparently, when the port is in the process of being updated, it is not zero. Anyway, I'm assuming there is a simple fix, but I'm having no luck finding the Easter egg. Any help would be, as always, very much appreciated.

You can approach your problem in a couple of ways. The way you've got it written now, as soon as the number of bytes is non-zero, you read and convert. This means that when a partial string is there, you conversion is nor correct. One way is to wait until non-zero bytes like you do now, and then in another loop, read until the byte count is equal to zero and then do the conversion. You can also read until the cr\lf is detected and then do the conversion on the string. You can also enable the termination character for the read but then you'll have to increase the number of bytes to read to something other than just the number of bytes first available. If the instrument always returns the same number of bytes, you can use that as a constant for the VISA Read. Then the read will terminate whenever the byte count OR the termination character is detected.
I modified your VI to show you how you might put it in a loop and what for the CR/LF to be detected. You would want to add a timeout to this so that if the character does not show up, the loop will not run infinitely

Satellite Pro 4260: How to remove the DVD drive?

I have a Satellite Pro 4260 and it appears that the DVD drive is broken and I want to replace it. I cannot figure out how to remove the old one.
Does anyone know how? Is there a manual available showing how?
Thanks

Hi
This notebook is not know to me but a checked some sites in the net and it seems that the top cover must be removed.
Then lift up the CD-ROM/DVD-ROM drive to disconnect PJ700 on the CD-ROM/DVD board from PJ15 on the system board.
Remove two screws securing the CD-ROM/DVD-ROM connector board.
Separate the CD-ROM/DVD-ROM connector board and CD-ROM/DVD-ROM connector brace from the CD-ROM/DVD-ROM drive
Well, I think its not easy for someone with no experience.
Therefore if you dont know how to do it and you have no much experience you should ask someone how knows what to do ;)
