• virtual serial port? Vista 64-bit, usb, palm 755 p verizon dongle

  I have a new Vista 64 bit operating system and I'm having problems that everyone else is still.  Can't hotsync using the cable.  I bought the dongle bluetooth (Kensington) that many have said works.  My phone recognizes the PC.  My instructions on the phone that warm using bluetooth synchronization tells me to set up a virtual serial port.  The instructions are not very clear.  This is where it falls apart for me.  Can someone explain how to configure this virtual serial port?  Thank you.

  Well, I'm pleased to announce a successful solution.  On the recommendation of some other son that I left and piece and ioGear GBU321 Bluetooth USB key and Setup was a snap and it works (although SLOOOWLY compared to a connection cable, a while and plug your treo during your first sync).

  To setup you do the following (and this can also work for your Kensington):

  • Insert the driver CD
  • Insert the dongle when asked.
  • Install the drivers
  • Pair your device.  Basically, go to the configuration Bluetooth on the Palm screen and select "Trusted Devices".  You will find the bluetooth adapter, select it, and then the Palm or PC will provide or ask a pairing code.  The instructions will guide you through, but basically, you'll want to make sure that the same numbers are registered on both screens (this prevents you from accidentally pairing with some random near the computer)
  • This will actually set up your virtual port for you.
  • You can go to the hotsync Manager and click on "serial" and select the port created in the pairing process.
  • If you don't know which port has been created "Control Panels" and select "Phone and Modem" (assuming that you are in "Classic view").
  • Click on the modem tag and you will see something like 'Standard Modem over Bluetooth link' and next to that it will be the assigned port.

  I hope this helps.  I know that I was relieved not to have to trash my Palm or my PC (although when the Pre or iPhone with a physical keyboard comes out all bets are open)

• virtual serial port (offered by a USB device) may not be reopened once the device has been lost and reconnected

  To connect to a virtual serial port offered by a USB device.
  -Physically disconnect the device (disappears from the entry in Device Manager)
  -Reconnect the device. (It reappears in the Manager of input devices)
  -Close the file handle
  -Reopen the virtual serial port. --> the CreateFile() call always fails with "ERROR_FILE_NOT_FOUND".
  -After dis - / reconnect the USB device once, the serial port can be reopened

  Even the true return of GetDefaultCommConfig there yet in CreateFile().

  It is clearly bad habits, because in our case the disconnection/reconnection occurs due to a restart of the device; and it's quite embarrassing to explain buyer for the disconnect/reconnect the device.

  Is there another workaround solution to clean the window's internal data structures or show me how to open the port?

• How to access a host USB Virtual Serial Port from a VM Application?

  I have a Linux VM running under VMware Player 5.0.2 on a Linux host machine.   I have a development system running on the computer, virtual trying to download the code on an external device connected via a virtual serial port USB host (ttyACM0).   Anyone doing programming Arduino device will be familiar with my software/hardware config.  Dev VM system does not directly hear the ttyACM0 port I need to establish some sort of connection bridge between "ttyACM0" host port and the port of VM-configured "ttySx"?   Someone did something like this with a VM Player?

  FYI, I found the answer to my own question in an old post on a similar topic. Here's a response provided by the user 'Worker' in the former post office that was the solution to my problem.  I followed its general approach and mounted my own virtual *.vmx machine configuration file to change the serial port set of ' / dev/ttyS1 "to" / dev/ttyACM0 ' I can now download code on my device directly from the Arduino IDE running on the guest VM system.

  Worker (1 positions since November 23, 2010) November 23, 2010 12:56 am (in response to AnthonySowden)

  A bit of an old thread here, but I wanted to say that I was able to do exactly this yesterday using VMware Server 2.

  It wasn't easy, but I managed to hack in there.  I guess that this trick works also on VM WS but I have not yet tested.

  Here are the steps:

  Start your VM turned off.

  Add a serial port of your virtual machine through the normal interface. -J' I just let it use/dev/ttyS0.

  Go to your virtual machine folder and edit the .vmx config file.

  Find the line:

  Serial0.filename = ' / dev/ttyS0 ".

  Replace:

  Serial0.filename = "/ dev/ttyUSB0 '.

  and off you go.  The guest operating system sees it as a real physical serial port and is fortunately out my system through series console!

  Hope that helps other people.

  Hi David,

  The error is because you don't have to specify the 'fileOperation' in the VirtualDeviceConfigSpec to add serial ports. The virtual machine correctly, reconfigure if you remove the following line:

  > fileOperation = > $fileOp,

  In addition, properties "pipeName" and "end point" of "VirtualSerialPortPipeBackingInfo" are strings. Thus, instead of

  > my $endPoint = VirtualSerialPortEndPoint-> new ('server');

  > my $vdpName = VirtualDevicePipeBackingInfo-> new (pipeName = > $pipeName);

  You simply do:

  > my $endPoint = "server."

  > my $vdpName = $pipeName;

  Hope the above helps you to resolve the error.

• Virtual serial port: no bytes to the serial port before you read visa

  Hi I want to use LabView for data acquisition in real time from my dc servo motors. I'm new to LabView, so I will try to do the same thing with virtual port. I am writing some data (a sinusoidal wave) to the virtual port and can read and display it on the chart. the writing part just works that we see in the hyper terminal. but he's not reading anything. the number of bytes to port is zero. I tried to put the number of bytes in visa read manually, but it does not work. I have attached my code below. any comment is appreciated. Thanks in advance

  This is just the basics of how communication works series. To do a reading without any instrument, you loopback (short) the transmission line to the receiving line. For a connector 9 pins, you short-circuit pins 2 and 3. If you have not done this, I do not understand where you thought you could do a reading of.

  In any case, if you have servos that are controllable of RS - 232, it isn't likely that the series is even close to what you do a closure won't tell you much more that the converter is functional. When you have a real instrument connected, you still need to debug settings com (baud, parity, handshake), type of cable (null-modem or directly through) and the actual orders that you send to the instrument and its answers.

• Tecra M11 - 17V - identify the serial port on the docking station

  I have a laptop Toshiba Tecra M11 - 17V, which I often use with the docking station that accompanies it.
  There is a DB9 serial port at the back of the docking station, but I don't know what COM Port.

  I use Windows 7.

  In the device, COM9 Manager - COM22 are identified as Port BT (bluetooth). Com7 - COM8 are RIM Virtual Serial Port v2, COM17 is Prolific USB-to-Serial Comm Port and COM18 is USB-Serial CH340.

  I thought that COM17 or COM18 were the most likely candidates, but have not been able to get to answer using one of them.

  I connect a Psion 5 (Comms app) to him and have developed ports and the Psion 8bits, 19200 baud, no parity, 1 stop bit.

  Hello

  > There is a serial port DB9 on the back of the docking station, but I don't know what COM Port, it is

  I think you have misunderstood something wrong
  COM ports in Device Manager are virtual com ports
  There is no link between a serial port and a virtual com port.

  I have a question: what docking station you have exactly?

  I had an express port replicator and this device required an additional serial port driver installation.

• VISA from read/write to serial port - unable to implements several orders of writing!

  Hello

  I'm new to Labview and I'm reading from a pressure through a virtual serial port USB sensor. I am able to read the port when you use HyperTerminal

  The code sequence that I should write to the port in order to obtain measurements using hyperterminal is the following:

  ' *' (2A hex)-online start and the responses of the port by asking 'Command', I should then enter

  FF-online measurement select the port must ask the 'mode', so I should enter

  0 has-online measurement of high resolution mode and it was then that I should start receiving action.

  The port is always answer by errors when I write the start command or the FF one. I tried to establish a sequence stacked to write the three commands then read the port, I added some delay between the three of them, but it does not work.

  Now I made really simple and removed the stacked sequence and just put the three commands one after the other and try to remedy not to not on the code.

  I'm really stuck at this point, could someone help me please? I read a lot fo articles on the forum, but I can't solve this problem

  Thank you

  I have attached my VI and the SCP1000 documentation (I can provide other versions of my demo if necessary)

  The reason for your problem is a frequent misunderstanding even among experienced programmers. Take a look at this thread

  http://forums.NI.com/NI/board/message?board.ID=170&thread.ID=417750

  In your data sheet, then they return codes like 0xFF or 0x0A so has a single byte of average value. Then you in your-active code constant writing FF\n is so this equal to values in format hexadecimal 46460A and your instrument do not understand. But it will include FF0A. In order to solve your problem, you would type in \FF\n in your '-' chain helped codes. Remember too, if you type in \32 it will be converted to character 2 this being 0 x 32 50 decimals and code ASCII 50 is equal 2

  Take the time and change the display format of string between '-' display and Hex display and you will see the difference

  Hope this helps

• enable/disable serial port

  Hi all

  I'm using Labview to communicate with a virtual serial port to PIC de Microchip. Occasionally the comms set is lost. To retrieve the connection I open Device Manager then right click the defective comm port, then select Disable (a red cross appears on the icon). Then right click the port again, and then select activate. The port now is successfully again.

  Is there a way to use the Exec System to control this behavior automatically once it occurs a failure or another method for drive C: using the methods and properties?

  Thank you very much

  Chris

  There is a command line tool called "devcon" which offers the same functionality as the Device Manager, only from the command line.

• Virtual Com ports never get reused after UN-installing of software that use

  I have install and uninstall the bluetooth drivers (Microsoft, broadcom and bluesoliel) in order to obtain different devices to work. When I started this exercise, used by bluetooth comm ports were low numbers (com 4 and 5 for example). If I uninstall the bluetooth drivers, then reinstall the or some other driver, the com port numbers used become com 6 and com 7).  Old ports com can never get reused and there seems to be any place where I can find them (and I hope that free them from their State of limbo).

  Now that I've got things nearby work properly, I get to com 25.

  This also happens with the bluetooth drivers not as my GPS through a series of USB converter. or my palm for synchronization software.

  That is to say the problem is not just with bluetooth. It's with any program that uses a serial port.

  I'm afraid I might run out of com ports, and perhaps these unused com ports consume resources (are they built during startup?)     Hmmmm... Looks like I ran out of space... Al

  Hi again
  Well, I made a variation on your theme
  1 turned on or plugged in devices that could use a virtual serial port - 3 of them
  com 26 2 with one of them, I have attributed it to 25, then 24, etc. all the way up to 3 comm
  That unlocks (disabled the use in indication) for all of the unused ports.

  reassigned the 2 remaining ports to com 4 and 5

  Thanks for the help

• Data NMEA which are received on the serial port, when the system starts causes windows 7 to interpret these data as a serial ballpoint mouse and moves the cursor jumping around.

  I know this question was asked several times before, but the solutions proposed, such as changin the registry does not help. It changes by itself. In the configuration that I have in my boat, the stream of NMEA data is directly injected into the COM port so no driver is necessary. It's a problem easily solved in windows XP, why is it so difficult in W7? There must be a way to permanently disable the plug-and-play driver load. I found this program that works only for Vista, if I understand correctly: http://www.stentec.com/en/download-freeware COM port plug & play blocker. If something similar could be provided by MS for W7, it would be very good...

  It turns out that the program at the port of Stentec COM (freeware) http://www.stentec.com/en/download-freeware care & play blocker, also works in W7. I don't know how it works, but it does, and it's good for me! It also works for the virtual serial ports.

• Windows XP does not allow applications to use the virtual serial (COM) Ports

  Operating system: Windows XP Professional version 2002 Service Pack 3

  I want to use some applications to control virtual serial (COM) on a device of PEARL IOLAN STS8 D/TruePort ports in Windows XP Professional SP3. When I configure the IOLAN/TruePort I see the COM ports in the Windows Device Manager and I am able to configure my applications to use ports.  However, when applications try to open the serial ports, I get an error saying that the port is already in use or does not exist.

  I tried various alternatives to remove/re-add the ports 'in use' in Windows before you configure IOLAN/TruePort and applications. This (sometimes) allows me to use the ports but if the PC is turned off later and rebooted the problem reappears.

  Is there a reliable way to create and use virtual COM ports in Windows XP?
