• script to find VM with configured serial port

  I'm looking for a script powershell list all virtual machines with a configured serial port. someone has already written one? I looked at the health check and scripts of type I could find, but could not find a list of the serial ports on the inventory.

  Thank you

  Mike

  Try something like this

  Get-View -ViewType VirtualMachine | %{
       if($_.Config.Hardware.Device | where{$_.gettype().Name -eq "VirtualSerialPort"}){
            $_.Name

• Problem with the serial port and external DLL

  Hello

  I have a Platinum (innco systems CT 0500), which is connected via a USB-RS232 to PC Converter. I want to fight in LabVIEW.

  The software CD contains a DLL and a header file - I imported both in LabVIEW.

  But I am unable to get a connection via LabVIEW COM port. There is an error of the adage about function ConnectTurntable() return code 'could not open port - port address is unknown to the PC or port is used by another program.

  The demonstration of the delivered CD software works - the connection to the COM port is working with him, so there must be a mistake in my LabVIEW Code.

  Thanks in advance

  
  

• INTERNAL SERIAL PORT (RS-232, DB-9)

  I need to find a new model laptop which still has an internal serial port (RS232, DB9) for all connections of equipment we need to do.  Can someone tell me if HP still has one and which one.  We bought several units ProBook 6570 b a few months back, but they seem to not be available now.

  Louis, as requested, I write back with what I discovered.  The HP ProBook 640 G1 and G1 650 ProBook equipped with a serial port internal.  I am convinced that it is useful.  I ordered actually only a unit of i7 640 G1.

• Change Windows 7 default serial port settings

  I need help how do I change the way Windows 7 control a default serial port COM1.  I use a serial cable very easy to control the special with external hardware.  The serial cable only use the RTS and DTR, GND pin of the cable and does not require special hardware drivers.  I used the camera on several versions of Windows 95 to XP without any problem at all with serial ports.  With Windows 95 - XP serial COM1 port's RTS and DTR lines defined 'stop' by default.  I just upgraded to a new computer with Windows 7 and now have a problem with the serial port.

  For my problem, I need to have the serial port to be 'stop' default until load control software and specifically opens the serial port to turn on the external device.  Using a serial port data Tester (a lot of green and Red led) I see that as soon as Windows 7 starts, it automatically sets the lines DTR, RTS and TD to serial port as "HOT" (high voltage).  This is not acceptable because it activates the external hardware until the control software is loaded!  Similarly when the control software is closed and the serial port is released in Windows 7, the serial port DB, RTS and TD lines are again defined as "HOT" (high voltage) by Windows.

  Computer: Dell Optiplex 745
  Windows 7 Pro 64 bit with SP1 installed
  Serial port on motherboard: Intel ICH8/ICH8R LPC Interface Controller 2810
  Serial driver: Microsoft 6.1.7600.16385 (is up-to-date)

     Settings for COM1:
     -------------------
     Baud Rate:     9600
     Data Bits:     8
     Parity:        None
     Stop Bits:     1
     Flow Control:  None
  

  I spent hours looking at the Manager of devices/port settings and try to find anything online with no luck.  Is it possible that this is because of the way Windows 7 plug-n-play manages the serial port?  How can I turn it off then the port by default as if it was on XP and earlier versions of Windows is 'off '?

  Thanks, Dave

  Dave,

  I can't believe that you have not answered this question.  I had the same problem as you trying to control my radio interface.  I just came by for a Dell Optiplex over the weekend and noticed the same problem.  I was searching the Web for an answer when I found this post.  I am happy to say that I found the solution to my Optiplex and how it works for you.  I went into the BIOS and set the UART protection on.  Makes no sense to me because I'm a software guy, only an amateur on the hardware side.  I left the BIOS and the serial port works as it should like in XP.

• PCMCIA card as a serial port RS232 on Satellite Pro 4200

  I think to use a PCMCIA card as a serial RS232 port. The program that I need to use runs under DOS and needs two serial ports. My question is that I need to run the program and the serial port to be recognized by the system. I have a satellite pro 4200 laptop PC series.

  Thank you

  Why on Earth if you want that?
  Your laptop computer with a serial port doesn't have it?

  Well for the serial ports are standard supported on Windows. In a back box that should be no problem.

  But pure back could be a problem.
  I guess you must also BACK drivers for your PCMCIA card...

• How to transfer files from PC to PC via a serial port using labview

  I need to transfer files (.txt, .doc, .xls) from PC to PC via a serial port using LabVIEW. Is it possible to transfer files, if so how to transfer?

  Yes, it is possible to transfer files with the serial port using LabVIEW.  The files are just collections of bytes and the serial port is good enough in the expedition of the bytes from one PC to another.  You must connect the ports series with a null modem cable.

  First, take a look at the example of serial communication.   In LabVIEW, go to the Help menu and select «Find examples...» ».  From there, you can search for "serial" or navigate to hardware input and output > series.  Select «Write series base» and Read.vi  Try this example to gain confidence on the serial communication methods.

  Then it's time to learn how to read and write files.  For this, the examples might be somewhat confusing as they deal with files that are presumed to have data of a specific type in them.  I would recommend just familiarize yourself with the functions in the file e/s palette.  Specifically, familiarize yourself with the following functions.

  1. Open/create/replace file - on the side of your destination, you will need to create the copy of the file you are trying to transfer
  2. Close the file - when you're done reading or writing to a file, you must close it.  It cleans the memory used and finalizes write operations that are still floating in the write buffer.
  3. Read a binary file - is the best way to play a file when you don't really like what type of file it.  In your case, you just want to get these read bytes and sent so they can be written down instead of destination.
  4. Write to a binary file - next to the destination, is what will store the bytes in the file that you created with the number 1.
  5. Size of the file get (under the range of the advanced features of file) - you need to know how big the file is, so you know when you are finished.

  OK, so once you are able to create files byte write and read bytes from existing files, you can move forward.

  I suggest the basic method is to have the user specify a source file on the source PC, and a folder on the destination computer.  Then find the size of the source file using the number 5.  Divide this number of size by the number of bytes that you want to transfer to the times.  The series pads are usually around 32 k (if I remember correctly) in order not to exceed that.  Now start to send data by reading a number of bytes and this string output wiring to the feature of writing VISAS.  On the side of destination, you will want to monitor the serial port for bytes and read when they arrive.  This string of yarn to the writing of the function of binary file to add them to your destination file.

  This is the basic outline of how to do it.  He needs to not to overload him write and read buffers on the serial ports.  Initially, you can use delays on the side sending to make sure that the side reading has enough time to digest.  To make things faster, you can bring in a control of flow.

  If all that sounds a little intimidating, there are there Alliance member companies (such as the automation of PrimeTest) who can write this code for you and even provides a turnkey for you solution.

  Happy wiring,

• Having problem of PCI and PCI communication serial port

  Hello guys,.

  I have a problem with my serial port PCI and PCI communication, I use Windows 7 64 bit found no solution please help about this and I am very happy to thank

  B.Regards,

  Hussain SF

  Hi Hussain SF,

  Thanks for posting your query on the Microsoft Community.

  I imagine the inconvenience that you are experiencing and will certainly help you in the right direction to solve the problem. However, I would be grateful if you could answer a few questions to refine the question in order to provide you with better assistance.

  1. You get no matter what error code/message when connecting to the serial port PCI?
  2. What is the brand and model of the computer/motherboard?
  3. What card has been inserted in the PCI slot?

  PCI stands for Peripheral Component Interconnect. It's an industry standard bus to connect devices to a computer.

  A serial port is a serial communication physical through transfers of information inside or outside a bit at a time. The term "serial port" usually identifies hardware more or less conforms to the RS-232 standard, designed to interface with a modem or a similar communication device. The serial port used to be widely used to connect to a variety of devices external and is essentially a two-way communication port. There are still devices using a serial port connection. These are often marked as RS232 and would include devices such as TELEVISION receiver cable boxes.

  The PCI of Simple Communications controller is a generic label given by Windows for PCI cards installed in a PC when the drivers for the device are not installed.

  You probably received this error because you have not installed the driver for your PCI device.

  If your computer came with a motherboard driver disc, put the CD in and install the chipset drivers from Device Manager browse the CD. This would update the drivers for those devices.

  Steps to follow:

  a. right click on the entry in the Device Manager and select Properties.

  b. in the driver tab updated some drivers.

  c. Select Browse my computer for driver software.

  d. click on browse and look for DVD player option.

  e. follow the instructions on the screen and restart the computer after installing the drivers.

  If you don't have the motherboard drivers CD then please download and install the drivers for the chipset of the manufacturer's Web site and see if it helps.

  Get back to us with all the information and results of proposed suggestion. We will be happy to help you.

  Kind regards

• serial port

  Hello
  I have a HP (DL 380) with a serial port server. I would like to know if it is possible, use the serial port when I make a virtual machine with vmware vsphere 5. So if this virtual port is Port Pass Through... So the question is: is it possible to use a physical serial port on the virtual machine with vphere 5?

  Thank you

  That's right, the old versions of ESXi does not support physical series (http://kb.vmware.com/kb/1003129) connections. Anyway, ESXi 5.0 is not mentioned in this article.

• Physical serial ports are supported in ESXi?

  Physical serial ports are supported in ESXi?  I install Windows 2008 SBS on a HP Proliant ML350 G6 ESXi (version of stick USB HP) running. The server comes with a serial port on board.  I was hoping that connect an external modem and expose it to the virtual server, Windows SBS 2008 to serve as a network fax.  Is this possible? Alternatives if not supported?

  It would be a no.

  There are TCP/IP USB devices, do not know if there are similar devices for the series, but NO physical devices, sound cards, usb, parallel, series can be transmitted to a virtual machine.  That's because ESX uses vmotion, and it was designed to let the virtual machine move between machines, so allowing physical connections so would interfere with this operation.

• Portege M200: serial port does not work with port replicator

  Hello
  I have a Tablet m200 and the top mentioned dock/replication PA3314-1PRP port.
  As the M200 has no serial port (rs232), I want to use the one on the docking station, but it is not recognized as a device on my tablet.

  Thew network connections and usb ports all work fine and the lpt port is shown in Device Manager. I have restored the Tablet and it still does not recognize the serial port.
  How can I get this port recognized so that I can use it.

  Thank you very much
  Lee

  Hello Lee

  I just, I can confirm that when you use the Replicator port advanced III with Portege M200 several ports do not work. Problem is that Portege M200 does not support these interfaces.

  This is a technical limitation and the port of mouse PS/2 port keyboard PS/2, serial port, I.Link (Firewire) port and DVI port will not be supported when Portege M200 is anchored on the Advanced Port Replicator III. :(

• Serialize the data into several messages from serial port

  Hello

  My current LabVIEW project, I want to read data from the serial port and store the (transformed) response in a file.

  Since my design model is based arround the Manager of messages queued waiting my serial communication is also build around that. (see this post for my original question).

  But now I have the following problem:

  In the loop 1 I put several messages in the queue of loop 2.

  Loop 2 processes these messages and sends them to the print queue of loop 1.

  Loop 1 gets several messages that need to be combined into 1 string and (with other data) in a file.

  Just to clarify:

  Loop 1, I have send 3 messages for each connected device. Even though I have a separate file for each device, the response to the messages must be in 1 result string.

  

  (Note on the picture: there are other loops running at the same time you will also need to access the serial port for the port for loop 1 is not an option)

  Hope you can help.
