• How do troubleshoot you a USB virtual COM port?

  Object

  Send orders of Labview to an Arduino board using the Advanced Serial write and Read.VI.

  The problem is that no orders are received by the Arduino.

  However, I can use the Serial Monitor built into the Arduino IDE to send commands to the Arduino and get the required result.

  I checked baud rate, the designation of COM port and the command is a simple as string 600,0.  The VI shows no error message.

  So, I'm looking for suggestions on how to troubleshoot a USB virtual COM port.

• How can I create a USB Virtual COM Port

  Windows XP Professional / SP3 / 2002 Version

  How do I create a virtual COM Port to USB, so I can run software applications of a Bus USB flash Drive?
  The reason why I am eager to do it, is because I use an audio sequencer and it requires 1 GB of free disk space and at least 1 GB of RAM is recommended. My machine has 0.5 GB of RAM and a total of 6.55 GB of FREE space. My machine has a 256 MB RAM module and I bought another 256 MB RAM module. The manufacturer said that 512 MB of RAM is the maximum that can have my camera.
  My goal is to buy a 4 GB Flash drive and use it to add RAM on my machine. I am also wanting to be able to run software applications that are installed in the USB Flash drive.
  My basic goal is to install the DAW in the USB Flash drive and work with the program that is in the USB Flash drive, and I hope that will release of enough memory on my laptop.

  Hello

  Unfortunately, you cannot use a USB flash as a substitute for the RAM drive.

• 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?

• virtual serial port

  I have a portable satellite wih only USB ports, now I have a GPS18USB but the Route66 programm wil only work with a gps series. I have now that it is possible to create a virtual serial port that can help me and tell me how
  email please at [email protected]

  Hello Hans,.

  I had searched the internet on installation of a virtual COM port, but I only find solutions based manufacturer. So I think that the driver or the software that generates the virtual COM port is based on the product that you (in your case, the gps system).

  The manufacuring company request a solution!

  But if they don't have a solution, I found a link on the internet that might help you! But if you want to test I will assume no responsibility for the consequences such as loss of data after a system crash.

  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.

• USB to serial port, Com port to use.

  I have Windows 7 64 bit Ultimate, evga 58 MB Intel i7 950 3.06 GHz, 6 GB ram, many locations for usb. I have a weather station "Oregon Scientific WMR968, I plugged my XP PC via a"usb to serial"cable, it worked well, giving me a com port to use for the software, but it does not work with Windows 7. It installs an input usb device, under the label HID, but not a COM port I have tried many drivers, but she finished in the same way, "peripheral usb entry" NOT a COM port I have tried to install .inf and who does not work either. I tried to update driver, and then point to the .inf and still no good. How to do this job, please. ?
  Frustrated,
  Robert

  Hi Androman,

  First of all I suggest you to check if the Oregon Scientific WMR968 is compatible with windows 7 or not.

  Check out the link given below to the windows Compatibility Center 7.
  http://www.Microsoft.com/Windows/compatibility/Windows-7/en-us/default.aspx

  If it is not compatible with Windows 7, then install the drivers in XP sp2 compatibility mode and also to contact the manufacturer for drivers that are updated that are compatible with windows 7.

  Select the option for windows XP sp2 and install the drivers.

• USB to Serial Port Adapter

  Hi, my laptop is not a serial port.

  If I want to connect to some hardware using RS-232, RS-485, CANBUS etc, will I have problems using a serial USB adapter?

  When I was programming PIC microcontrollers, we were told not to use adapters to program the PIC. I found this a little confusing because the signal from the adapter must be identical to what would come of a serial port. I don't know what is the reason.

  Are there any known issues using a serial USB with hardware adapter (specifically the sbRIO-9651 reference carrier I use and also just in general) or I would be fine to use it?

  I have a box of NI USB - 232 which will stop working.  Not sure if it's a loop of mass or something with signals through it, but... Yes, they didn't last real long in my experience.  (It was years ago, I sent a bunch of back, don't know if improvements have been made since that time.)

  IOGear GUC-232 has and from SILabs CP2102/MAX3232 work well for me. never had a problem with those.  Anything FTDI is solid, beware fake chips with this manufacturer.

  7Fh has a HID-UART chip available (CP2110), which works well on machines that have restricted permissions for driver installation.

• drivers for USB to serial port cable

  I am trying to install drivers for a USB cable to serial port on a HP Pavilion dv7 laptop (Windows 7) - I go through the download and when I plug the cable of the toolbar displays a sequence of installation but then an error of installation failed. I tried all sorts of updates and Windows says that it cannot verify the signature of the device.

  Would have been nice to know exactly what you had already tried :-)

  I do not know what adapter you are using, but I have a Trendnet TU-S9 that I use to connect my OBDII code reader to my PC, so I can save the CEL errors that I receive on different vehicles. I thought I had the drivers for it installed, but I have not (could not even find on a HARD drive). But I plugged it in just to see what happened. The message was that no local driver could be found, I wanted to try Windows Update? I said yes, and installed a "Prolific USB - to - Serial Comm Port (COM3)". Plugged the code reader, started the PC-Link software and here!, everything was good.

  You could try to uninstall anything that you have already installed, restart, then connect the adapter and see if you have the same success. I use Win7 HP x 86, but Vista should at least try to do the same thing, and who knows, it might work :-)
