• Problem removing battery bluetooth / hidden devices / unpublished COM ports

  Hello
  Having problem completely remove Toshiba Bluetooth stack / hidden devices / unpublished com ports

  I uninstalled Toshiba BT s/w...

  But:

  (1) peripheral BT Toshiba hidden appear again and I can not remove (get the error)

  (2) the COM ports occupied by Toshiba BT not out (so they cannot be used by another pile of BT) and always appear in the registry
  ex: friendly name Toshiba BT Port (COM4) always in the registry

  (3) these new com ports do NOT appear in Device Manager

  Thank you

  What COM ports are actually used (must be used) by your current system?

• USB/Virtual COM port Communication problem with ESP301/LabWindows/CVI

  Hi all

  I have gone through different threads posted in this forum for similar issues and all tried, but nothing helped.

  I'm trying to communicate to the ESP 301 training monitor via a USB port configured as a serial COM port using a CR. Have it ' command is to get the version of the controller. The "write" "ComWrt" command works fine but the read command throws and error ("-99 operation e/s timed out"). I tried all the suggessions; with delays etc... who has explained (resolved by Mr. RobertoBozzolo) in the thread posted here, which explains an issue similar to that of the mine, but the help couln t.

  The code is attached.

  I am using 2012 LabWindows/Windows7 64 bit multi-hearts

  int Get_Version () {}

  comport = 3;

  BaudRate = 9600;

  parity = 0;

  DataBits = 8;

  StopBits = 1;

  inputq = 512;

  outputq = 512;

  ctsmode = 1;

  xMode = - 1;

  Timeout = 5.0;

  com_status = 1;

  char comstring [6];

  DeviceName [] = "COM3".

  Int State = 0;

  char * error;

  int bytes_written = 0;

  char Cmnd_String [50] = "";

  char Read_String [512] = "";

  strcat (Cmnd_String, "ve?")

  strcat (Cmnd_String, '\r');  Tried to 0x0d
  strcat (Cmnd_String, '\0');

  length = strlen (Cmnd_String);

  assert (Cmnd_String [length] == you? \r\0'); Tried Cmnd_String [50] = ' VE? \r\0 ".

  DisableBreakOnLibraryErrors ();

  RS232Error = OpenComConfig (comport, devicename, baudrate, parity, stop bits, inputq, and outputq data bits) ;// tried ouputq = - 1 too

  EnableBreakOnLibraryErrors ();

  If (RS232Error == 0) {}

  com_status = SetCTSMode (comport, LWRS_HWHANDSHAKE_CTS_RTS_DTR);

  MessagePopup ("Comport verified',"CTS Mode works very well");

  com_status = SetComTime (comport, timeout);

  }

  bytes_written = ComWrt (3, Cmnd_String, (Cmnd_String) StringLength);

  If (GetOutQLen (3)! = strlen (Cmnd_String))
  ComWrt (3, Cmnd_String, strlen (Cmnd_String));
    
  status = ReturnRS232Err ();      The status is 0
  error = GetRS232ErrorString (status); / / error number

  Delay (5.0); / / trying to add the time up to 20.0

  GetInQLen (3); Returns 0

  ComRdTerm (3, Read_String, 512, 13); Read from inputQ

  status = ReturnRS232Err ();               Status to return the error code '-99 '.
  error = GetRS232ErrorString (status); Error message "e/s timed Opération" out

  return the situation;

  }

  Can anyone suggest where I am doing wrong?

  Thanking you in advance.

  Another thing you should check is baud rate.  The ESP301 by USB is expected than the baud rate to 921600.  The function for OpenComConfig() group implies that it does not support this baud rate setting, but it seems to work perfectly.

• Cannot sync. -Com port in use error

  Win7 64 bit, PalmDesk 6.6.6, IR USB dongle. Tungsten E

  Has been able to synchronize the first two times with the new IR USB organization. I ended with triple calendar entries so finally was able to remove old items out of PalmDesk and after doing a hard reset on PDA, could clean the scheduling issues so I thought everything was OK.

  Then tried another HotSync and kept getting an error on the PDA "Cannot start the HotSync operation because the port is currently in use by another application"

  Spent 2-3 hours to get here and other sites for possible solutions. Found none so tried to Soft Reset and then reset hot but neither worked. Finally I did a Hard Reset.

  Was able to do a HotSync.  It took 6:30, but it does not seem complete.  Note that my memory is only half full

  Now, the real problem.  I wanted to see if I could do a HotSync and did not take hours to complete.  But still, I get the port in use message.

  The message comes even if the PDA is not connected to the PC by IR isn't something in the PDA.  He was going to install dbFix, but since I can't synchronize I can't install it.

  I note that after the Hard Reset did only 3 options under connections now, I have 6. There is an IR to a PC/handheld, but the details show that it uses really Cradel/cable. There is an infrared for GSM phone but I can not remove or change it. Also of IR to PC with a speed of 28.8 by default.

  Solutions, ideas or even wild guess appreciated.

  WyreNut

  Thanks for the reply, but you are not the first to suggest not correctly the problem was in the PC.

  I have finally resolved and am posting the investigation and the resolution here in the hope that others can solve the problems of strange synchronization they could find out by doing a similar detailed investigation.

  The error message not being able to sync because the com port has been used pop up would immediately after recording HotSync. I without having to be connected or even close to a PC to get this error message. I have confirmed that being in front of PC with IR, equipped of Vista 32 bit, so it wasn't a problem with Win 7 64 bit either as I had been able to synchronize PC Win 7 approximately 4 weeks earlier.

  I had 4 chat sessions with Palm TREES, where they provided a number of suggestions essentially to tell me that the problem was Win 7 based or 64 - bit based or that I did a Hard Reset if fixed (none of which were correct).

  I tried a number of sweet, hot and hard resets. The only time wherever I could sync was after doing a Hard Reset and synchronization takes then 3.5 HOURS to complete. I could never do a second Hot Sync that I always get the error message.

  I finally discovered that the list of connections is changing and the individual setting for one of the original connections was changed when I did the sync.

  After a Hard Reset, there are three connection options:

  PC Via cable/home station, Modem Via station home/cable and IR for PC/handheld Via infrared

  When I ran the Hot Sync more than two connections have been added to the list

  IR for GSM and GSM BUT phone serial

  The surprise that took a few moments to discover that the PC/handheld Via IR computer had its details changed to home/IR obviously cable station, I could use this connection to synchronize this is to create a custom connection which was the PC Via IR.

  The dropdown under HotSync would present the old PC/Pocket PC Via IR, but it does not work because he didn't was more IR I would choose the custom, but he made the mistake of com Port conflict

  The SOLUTION was to delete all backup and archiving files, install the PC off, do a Hard Reset of the PDA and then do a HotSync.

  This time sync took only 5 minutes, the connection list has not been changed and the settings in detail for PC/handheld Via IR were not changed.

  I don't know when the commands of GSM phone has been added to the list of options on the PDA, I never used the PDA as a phone. I'm not even sure who's App adding the GSM phone files. He could have been there for years I never had problems with synchronization with USB port and a XP machine. Even the first synchronization IR on Win7 64 bit machine worked so I thought everything was OK.

  Thanks for the suggestion anyway.

• The COM Ports on Satellite P10 do not work after the conversion to the WXP Pro

  I have a P10 (PSP13E-0372V) that I have upgraded from XP Home to XP Pro. Everything went very well and then I discovered that I don't have a COM port or at least Device Manager shows no COM port.

  If I try to dial, I get "Error 633 the modem is in use or not configured properly". Back to Bishop device to watch the modem which, it says, works very well. If I query the modem (Diagnostics) told me 'port that the modem is attached could not be opened. "
  Also, it is said it is attached to COM3 but I can choose any port and get the same result. (When I change the port I get the message "the port has been opened by another application. Renaming the port may have an unpredictable effect on the other applications")
  I tried to remove the modem and restart but no change.

  If anyone any ideas how I can get the modem to work.
  TFAI

  So any ideas on how

  Hello

  Usually WXP Home, Pro should work without any problem because all the drivers, tools and utilities can be used for the two operating systems. I just hope that you have preinstalled all things in order of good facilities.

  Have you installed the driver chipset from Toshiba download page right?

  The modem uses a virtual com port. It s not a real port.
  I wonder why it usually happens after the installation of the new operating system, you must install drivers Toshiba together in the right order
  Installing the chipset utility is important

  The modem driver should do the work and you n t need to activate com ports
  Please choose the right side of the page of the Toshiba driver modem driver after installing the OS correctly. I think that's the key

• How to change the settings of the BT COM port with the Toshiba BT stack?

  I have a Tecra S11 with Windows7 64 bit and I need to connect via Bluetooth to a remote the BT series device. I want to use the BT interface on board.

  The BT remote appliance 38400,8, N-2 (stop to the most common place 1 2 bits). Problem: I find nowhere to change local BT Com port settings.

  The physical port HW parameters can be changed. See:
  HW COM1 with the port settings: http://i42.tinypic.com/epg5qr.jpg

  But I don't get the same tab for the port of BT:
  BT COM40 without port settings: http://i40.tinypic.com/24mcduw.jpg

  Not even the BACK order 'mode' allows me to modify the ports of BT

  Curiously, if I have the COM40 to a virtual machine on the same S11-tunnel (virtualbox), the machine virtual XP * can * change settings and communicate correctly with the remote device. How is that?

  Can _How Yes, I change the port COM BT with the Toshiba BT stack settings? _ my version is 8.00.12 (T), which should be the most recent available. I also updated the BIOS.

  Thank you
  Paolo

  Additional details.

  I tried to run the application as Administrator: still does not work.

  I crossed Win registry with regedit and gave all permissions to all users: still does not work.

  With the registry editor, I forced the port in 38400,8, N, 2 in 'HKEY_LOCAL_MACHINE NT\CurrentVersion\Ports': still does not work.

  Note that not only the application target complains, but also does not work the PuTTY used as a terminal series.

  The Toshiba BT application see the remote device were undetermined, serial port, Dev.B. No provider.

  I'm lost and stuck. Advice greatly appreciated.

• Toshiba BT stack steals the puppetmaster COM port

  Hello

  I'm trying to connect my phone with the party program on my computer (master of puppets or perplexed) and 3D for who built a new server com port com3
  When my phone connects to his departure from the transition of data but not with the puppetmaster program so it must be with battery Toshiba BT.

  I reinstall windows, drivers, puppet master and all of a sudden it works but after reboot, it will have the same problem again.

  I found a thread about BT stack who steals the focus to another program, but with no information on how to solve this problem in the forum.

  Do I miss...

  Hello

  Master of puppets - the server is unknown to me but I found some practical information and it seems that you can assign different ports in the preferences-> the device selection

  Try to change that and check if it works with a battery of Toshiba BT.

  Good luck

• Re: How to connect to the mobile phone via the com port

  Hello
  I have problem with connecting my Nokia n82 (s60) phone to bt via COM port. I want to connect mobiola webcam and need it. Can U help please?

  Hello

  Satellite A300 Vista preinstalled
  Battery Bluetooth version 6.10.07
  Motorola Razor V3 mobile phone

  Not the same mobile phone, but the principle is the same.
  Without doing anything special, I connected my phone to the laptop in a minute.

  Allow BT using FN + F8
  Open Bluetooth settings, click the BT symbol in the taskbar
  Click on new connection
  Select the Express Mode > mode activate Visible on laptop > click OK
  On the new connection wizard, choose phone list and click OK
  When offered choose security PIN (for example, 1234)
  Check connection on mobile phone and enter PIN security
  After the PIN CPM40 control port will be enabled

  Then now is your phone connected to your laptop and you can, for example, transfer files from the phone to the laptop.

  By the way: what model of laptop do you have and which version of battery Bluetooth?

• VISA does not open COM port

  Hello, I made a simple VI which gets data from the PC com port.

  It works well on my desktop but today for the first time I ran it on my new laptop and it does not show the COM port. I see the COM port in Device Manager, but it does not appear in the drop-down list in my VI. Can someone please? I have attached my VI.

  Thank you

  You use a labview 2013? I had a similar problem and I had to install NI-VISA so that it displays. Not sure if you have installed that, but if not, then that should solve your problem.

• Name of the resource does not COM port number

  Hello

  When I connect computer Board, I use

  ResourceManager.GetLocalManager (). FindResources("?*")

  to get resource name ("ASRL11::INSTR") and use that name that I invoke

  A session = ResourceManager.GetLocalManager (). Open (Name);

  to get the session and get the value of the property HardwareInterfaceName of the session.

  The problem is that the COM port number in the property ("Com10") of HardwareInterfaceName does not match name the resource. The COM port number is correct, that it is the same, as noted in the Windows Device Manager. But why the name of the resource 'ASRL11::INSTR', it should be "ASRL10::INSTR".

  Does anyone have an idea?

  Thank you
