COM ports configuration

I need to connect a PDA Fijitsu Siemens Pocket Loox to the PC using the Bluetooth. I have successfully installed software for the dongle on the PC side BUT there is a problem to connect PDA to the PC using Bluettoth Serial Port. PDA Bluetooth software (Pocket PlugFree) is ALLWAYS using COM5 but this port on the PC is not available because it's occupied by Bluetooth Fax Modem installed from the dongle installation package. If I disable the modem then COM5 is still not available (niether COM6 and COM7, which are also blocked for Bluetooth Modem and Bluetooth Null Modem and also can't be reconfigured). Please, don't you know how to reconfigure COM ports for the dongle?
I use Windows XP on the PC. Both devices can communicate to each other and files can be transfered with no problem.

Hi
I had the same problem with my T61 and my HTC Touch Diamond, and found the help I needed here: http://lopsa.org/node/788
It did not work the first time, I had to do I a couple of times, but it finally worked out.
Hope you get your problem solved.
Best regards

How can I write to multiple daisy-chained network serial addresses through a single COM port?

I have a VI to write to 3 PI Mercury motor controllers using daisy chained RS232 connected via a Prolific USB-to-Serial adapter. I know that it is possible to talk to the individual controllers because the PI terminal that I have recognises the addresses of multiple controllers and designates them Device 1,2,3. The VISA resource name when configuring the port just comes up as COM5 most of time, with seemingly no way to specify an address on that COM port. Occasionally the VISA resource is ASRL5::INSTR and as this is disconnected and re-connected, this address moves up a number (e.g ASRL7::INSTR). Can anybody tell me how I can configure my serial communication to allow me to individually communicate with the different devices through a single COM port?

What does the manual say about addressing? RS-232 is not multidrop, the resource name is correct, and there is no additional configuration needed. There would have be a specific write in order to address a certain controller.

Can't run form from Form Builder 10g - Port configuration problem?

Hi,
I have installed the Database (10.2.0.1.0) and the Developer Suite (10.1.2.0.2) on two Linux machines (Red Hat Enterprise Linux ES 4 Basic).
If I enter the frmservlet-URL manually everything seems to be fine.
In one case I enter http://127.0.0.1:8890/forms/frmservlet, in the other http://127.0.0.1:8889/forms/frmservlet; in BOTH cases I get eventually a dark square and the status bar says "Applet oracle.forms.engine.Main started".
HOWEVER, if I create a simple form with Form Builder and click on the Button with the green traffic light ("Run Form"), the form runs only on the machine where frmservlet listens on port 8890.
On the other machine (frmservlet configured to listen on port 8889) Firefox pops up, the URL "http://127.0.0.1:32979/6dOrpwghCqnp8PhMT7KVT533m3IaArqFbPqPBOztZXWYSsNy" gets called, and nothing else happens. The screen displays the string "ORACLE FORMS." and the status bar says "Waiting for 127.0.0.1...", and it stays like this forever.
I assume this is a port configuration problem, but I don't have a clue where to start.
Any suggestions how I should proceed are greatly appreciated.
Thank you very much in advance!

Hi Frank,
Thank you for your reply.
I doublechecked my configuration.
In the dialog Edit --> Preferences --> Runtime the Application Server URL is set to "127.0.0.1:8889/forms/frmservlet".
However, when I attempt to run the form, the URL "http://127.0.0.1:33140/W2dwbV9eXS2fPkuKlxNhCxFWdEihwDviat2uV7ycrSotqwDN" gets called.
The screen displays the string "ORACLE FORMS." and the status bar says "Waiting for 127.0.0.1...", and that's it.
I wonder how the port number 33140 got selected. Interestingly, this time it is a different number; last time it was port 32979. In fact, the port number seems to change each time; I tried again and now it is 33189.
I will now try to set the port number for the frmservlet to 8890.
I choose Edit --> Preferences --> Runtime and set the application server URL to "127.0.0.1:8890/forms/frmservlet".
I stop the container, open /home/oracle/OraHome_1/j2ee/DevSuite/config/default-web-site.xml and change the port number to 8890:
<?xml version="1.0" standalone='yes'?>
<!DOCTYPE web-site PUBLIC "Oracle Application Server 10g XML Web-site" "http://xmlns.oracle.com/ias/dtds/web-site.dtd">



<web-site port="8890" protocol="http"
display-name="Oracle Developer Suite 10g instance of Oracle Containers for J2EE Web Site">

     
     
     <default-web-app application="default" name="defaultWebApp" root="/j2ee" />

<web-app application="forms" name="formsweb" root="/forms" />


<web-app application ="reports" name="web" root="/reports" />
<web-app application = "reports" name="demo" root="/repdemo" />
     
     <access-log path="../log/default-web-access.log" />
</web-site>
I restart the container, start Form Builder, connect to the database, and open my test form.
When attempting to run the form, the URL "http://127.0.0.1:33437/Pl0n3ky9vmU5z37A7ScBnQhsGwq3jwuzJpgTAKWPMOYIzT8K" gets called (again a new port number, apparently picked radomly within a certain range) and nothing happens: "Waiting for 127.0.0.1...".
However, when I enter the URL http://127.0.0.1:8890/forms/frmservlet I do (eventually, after confirming that I trust the certificate etc.) get a darc rectangle and the status message "Applet oracle.forms.engine.Main started", which tells me that my setup can't be that far off target.

Problem removing bluetooth stack / hidden devices / COM ports not released

Hi
Having problem completely removing Toshiba Bluetooth stack / hidden devices / com ports not released
I uninstalled Toshiba BT s/w...
But:
1) Toshiba BT hidden devices still appear and I can not remove (get error)
2) COM ports occupied by Toshiba BT not released (so they cannot be used by another BT stack) and still appear in registry
ex: friendly name Toshiba BT Port (COM4) still in registry
3) These unreleased com ports do NOT appear in device manager
Thanks

It seems that you still have some configurations which were not removed during the uninstallation.
This means that the resources can not be release, because those are still necessary in case of a
new installation of the stack.
The first I would try is the following:
- Install the latest Toshiba Bluetooth stack.
- Uninstall it. Ensure that you answer all questions with "yes" ! This means also the one which asks if all configurations should be removed.
- Reboot
- Check again

Serial COM Port to TCPIP

I saw a lot of posts that deal with this, however: I have a test rack with 24 UUTs, each has a usb to Ethernet adapter. I want to use each adapter to talk to the UUT with the same IP (can't changed it it's static). I need to be able to go through a com port and communicate to a specific UUT, knowing that I am communicating through this specific com port, not any other of the 24.
I saw a few virtual drivers, that seem to do this, but has anyone done anything of this nature before? I know I can create a NI Visa resource in NI MAX but that doesn't help me, because I can't link a com port to that resource, can I?

rsmrostov wrote:
‎You wrote that you have a USB-to-Ethernet adapter. Did you mean the TRIPP-LITE extender?
yes
That is simply a USB extender, no conversion to Ethernet. - obviously
Then why did you describe it as a USB-to-ethernet adapter?
rsmrostov wrote:
Does your device speak TCP-IP or serial? -TCP-IP
Where is the USB-to-serial adapter, and what model is it? non, there's a driver that comes with the device, that must let you talk to TCP/IP
Is it integrated into the DUT? - most likely, not sure to be honest, as I am helping out one of the guys who plain just doesn't know.
What can you tell us about the DUT? - Linux based device, has a fixed IP
You showed us a screenshot of MAX, listing several COM ports. So, those COM ports somehow exist on your system. You also said that only one of them is connected to the DUT. If this is true, then the COM port must be created outside of the device (for example, a USB-to-serial adapter). However, if the device doesn't use serial communications, then it doesn't make any sense to have a USB-to-serial adapter at all, because there's no easy way to run TCP over serial.
It sounds like you need to do some research on exactly how your DUT works, what types of connections it offers, and what protocol it uses. If you absolutely need to connect to multiple devices, each of which have the same IP address, I would recommend that you get a bunch of cheap home NAT (network address translation) devices, often seen as a home/office router (allows you to connect multiple computers to a single internet connection). Assign each one a unique IP address within the same subnet, plug them all into an ethernet hub or switch, and plug one DUT into each router. Configure the router's internet address to match the subnet of the DUT, and set each router to route all incoming connections to the IP of the DUT.

Switch port configuration for 3500i AP

Hi,
We are due to install a brand new enterprise WLAN based on the WiSM2 platform, 3502i AP and WCS. The APs will be plugged into the 2960S-24TPS-L.
I have scanned over all documentation and cannot for the life of me find a recommended switch port configuration for connecting the AP to the switch in terms of speed / duplex etc. For example, should I just configure the port to auto detect, or is forcing the speed / duplex the way to go. I could also do with knowing other best practice configurations for AP connectivity.
Any help would be greatly appreciated.
Chris.

The AP comes online with just auto detect, but I want to know if there are any benefits to forcing this to 1Gbps / Full duplex, or even if this is the right way to go. I suspect auto detect is the best method.

HTML DB and Serial(COM) Port

Hi, everyone,
Is there any way that HTML DB can communicate with Serial Port (COM Port) directly? I searched the forum, and saw someone mentioned "Visual Baisc", "Javascript", "ActiveX", or "DLL". Could anyone give an example for it if you had successful experiences about it?
My problem is I'm working on a HTML DB project which will read data from barcode scanner. And request I have is the HTML DB can monintor the Serial Port and read the data from there if there is one. That means some programs need to be embedded in or called in HTML DB page. I known there are some commerial software developed for this purpose on the market, but I am wondering if it can be done by HTML DB itself?
Thank you. And Regards,
Ran

> Is there any way that HTML DB can communicate with Serial Port (COM Port)
directly?
There seems to be a misunderstanding or lack of understanding about what APEX/HTMLDB is ito client-server architecture.
APEX is a server side application. It resides entirely in Oracle as PL/SQL software. It is executed by Oracle server processes that are servicing requests from a web (i.e. Apache) server.
APEX does not "run" on the client. APEX streams, via the web server, data to the client browser. These MIME streams can be anything from HTML, XML, plain text (like CSV data), to images and so on.
The browser receives this data stream, and depending on the browser configuration, does something with it - e.g. it renders a HTML data stream, it starts Flash Player plugin for a Flash graph, etc.
The browser interacts with the client. With the user, the mouse, the keyboard, the printer and any other peripherals the client may have - like a barcode scanner.
Can HTMDBL use a COM port? The more correct question is, Can PL/SQL in the Oracle Server Process access the COM port of the Oracle Server Platform?. The answer to that is yes - it can be done.
But in the context of client interaction and the COM port being that of the client platform - no. PL/SQL is a server-side language. It does not execute on the client in the client browser.
It is important to understand the web client-server architecture - as it is a lot more complex and inflexible and slower than the "traditional" client-server architecture. It is stateless. It uses a very "primitive" client, the web browser. It is bound to W3C standards which is the lowest common denominator. Forget about smooth and slick client GUIs using and supporting the latest desktop GUIs standards and controls. Forget about easily interfacing with the client platform's file system and peripherals and so on.

Wrong Com Port order with PXI - 8422 in a Win2k system

While using my PXI-8422 on WinNT4.0 and NI serial driver ver 1.44 Ports were assigned com numbers top to down. ie Port1-COM1 , Port2-COM2 , ...
However on win2k and NI serial driver ver 1.45 ports were assigned com numbers in the reverse order. ie Port1-COM4 , Port2-Com3 ,...
And when i try to change com assignments the sytem hangs while trying to access the ports.
Any idea how to solve it?

Topcu,
We have seen the reverse order behavior before for serial devices in Windows 2000.
The first thing is to make sure that you tried to change the com assignments properly. If you only tried to change them in Measurement and Automation Explorer, it may not work. Here is the proper way:
1. Select Start>Settings>Control Panel and double-click on the
System icon.
2. Click on the Hardware tab and click on the Device Manager button.
3. Double-click on the Ports (COM & LPT) icon.
4. Double-click on the port you want to configure.
5. Click on the Port Settings tab.
6. Click on the Advanced button. The Advanced Settings dialog box
should pop up.
7. Change the COM number in the COM Port Number field. (You can
use a COM number that is designated as in
use, as long as no hardware
is actually using that COM number.)
If this is how you tried to reassign your ports and your system still hangs, please go to www.ni.com/support and click on Request Support in the black panel to let us know.

Blackberry hijacked my serial com port!

Hello! I'm new to blackberries! When I tried to sync up my old palm device, it wouldn't connect. Checking into my serial com ports, I saw that the Palm M100 (aka old) was configured for com port 4. Looking on my device manager, I noticed that my Curve took over serial com ports 3 and 4. I intend to still use the palm device. How do I get the computer to recognize it without having to uninstall or reinstall anything?

change the USB port on which you connect your BlackBerry device.

COM-port problem with MSI BToes USB Dongle

I´ve had problem to get my Sony Ericsson T610 to work with my MSI BToes USB Dongle, so I tried to update my drivers. Now I have Microstar Bluetooth Software 1.4.2 build 10 but can´t get my Serial Port service to work. In Advanced configuration / Client Applications under "Bluetooth Serial Port" / "Properties", the only serial port I can choose is com0. Does anyone know how to fix this problem?
/Peter

Well, I think i´ve solved the problem. To get the com-ports to work I installed the software. Then I had a problem to get the phone to communicate with Sony Ericssons synk-software and outlook, but suddenly it worked and has worked since then. I have no idea what the problem was but now it works and I´m satisfied.

Com Port problem running XP

I am trying to communicate with a RidgeSoft IntelliBrain-Bot robot via an installed Radio Shack Serial to USB cable.
The XP system Device Manager shows the active port for the cable is COM3 and that it is working properly.
I have activated the "computer to computer by cable" modem and that is working properly.
With the bot Serial connected to my MacBook Pro USB and the bot turned on, the RidgeSoft program on XP will not start, stating it is an invalid com port.
I am working with RidgeSoft on this but wonder if any similar Serial to USB situations have occured which hopefully were solved?
P.S. I'm far more knowledgeable with a Mac than I am with a Windows machine.

OpenComConfig fails if the port is already open by some other process. Com ports don't have sharing semantics in Windows as far as I know.
The first question is what other process wants to use the same port? Configure the processes so they don't contend for the same port.
The locked port will release (it's a resource to the process) if the owning process terminates for any reason, even if it doesn't release the port. Windows will clean up resources that were held by a terminated process.
So you can release the port by terminating the process holding it, but the situaution shouldn't be happening in the first place.
I get caught by this sometimes when I have the port open using a terminal emulator (e.g. hyperterminal or terminal) and try to run a CVI app that then wants the port. It can be confusing.

Java is not coming up because of wrong port configuration

Hello guys
It is a ABAP+ JAVA system ,ABAP is system is up but java is not coming up because of wrong port configuration.
getting error as ....service could not start because of missing or wrong port configuration
also tell me how to change this parameter in configtool??
com.sap.aii.connect.integrationserver.r3.mshost

Hi,
Please attach std_server0.out file too. Also, on the Abap side, ensure the HTTP port is set. This can checked by tcode smicm->Goto-> Services. The HTTP entry must be enabled and the port number should be displayed.
If it isnt enabled, then activate the http port in the instance profile using RZ10 Tcode.
Also, AFAIK, the parameter com.sap.aii.connect.integrationserver.r3.mshost is maintained in the exchange profile.

Solaris com port

i want to talk to solaris machine's COM port through java which talks 64-bit and the sun machine talks 32-bit, so i need a library that convert from 64 to 32-bit.
If any one can help i'll appreaciate it.
Thanks

i want to talk to solaris machine's COM port through

32-bit, so i need a library that convert from 64 to
32-bit.
If any one can help i'll appreaciate it.This doesn't make a lot of sense. If by "COM" port you mean a tty port, then it doesn't talk 32-bit - it talks anywhere between 5 and 11 bits depending on how you've configured it.
Try explaining much more clearly what you are trying to do.
