Error 37 with serial port / no with hyperterminal

I have added to my Pc a card with two serial port, I can access to them by hyperteminal or by labview but only at port 0 and 1 at the same time or 2 and 3, if not I have an error 37. What can I do?

Error 37 means that LabVIEW cannot find the appropriate serial device. This indicates that one of the following conditions exists:
LabVIEW cannot open the specified serial port;
LabVIEW cannot find the file serpdrv.
Make sure that the serial driver was installed before the board, and that the com ports appear normally in the control panel. If you cannot get it working, contact NI through either phone or email support. Since there are several potential causes, this is difficult to diagnose without more information. You can contact NI using the following webpage.

Communicating with Serial Port

Hi,
Hi I have an application that i have to communicate with serial port...
Its working perfectly if am giving all the com settings as constants(pls hav a look @ codea).
But i want to read the port number and baud reate from text file.When i changed the coding,in the serial
setting i was not even able to find the port number and baud rate.it was displaying as buffer size.I think the way i connected the port number and baudrate to the clusture may be wrong(pls refer codeb).How do i fix this problem?
Thanks in Advance....

The problem I think is that you don't have a cluster tied to the center terminal of the bundler so most of the values don't have a name. Wire the cluster from above to the center terminal on the lower bundler. BTW, it doesn't matter what values are in the cluster you wire up because they will be overwritten.

Any way to communicate with Serial PORT using JavaScript

is there any way to communicate with Serial PORT using JavaScript ??
Dont tell me to do it in java because I need to this on client side not on server side.
such as when client pressed the button, a javascript function will be called and in that function I need to communicate with the serial port of that client... That action will not go to server side.

Is there any way to send a string of bytes to the serial port from the client side ?
Just a button on the web page that sends out stuff to the comport.
I was hoping to do this using java script also ..

Use a HP 34970a with serial port

Hello,
I have labview 7.0 and I have to use a HP 34970a with serial port.
Can anyone say to me any advice to do it?
Where can I find some material?
Thanks
Vincent

Hi Vincent,
> I have labview 7.0 and I have to use a HP 34970a with serial port.
> Can anyone say to me any advice to do it?
> Where can I find some material?
Your first step should be visiting http://ni.com/idnet and search for an
instrument driver for your device (in this case I can promise you will
find one).
The "Learn" link on the same page tells you more about instrument
drivers in general which could be helpfull if this is the first time you
are working with instrument drivers.

Fastest Thinkpad with serial port

Hello!
what is the fastest thinkpad with dock station or port replication that still have the serial port that has been produced?
Is it the X60 ?
I have my faithful T30 but it is a little slow now...
Ciao

Welcome to the forum!
Although the integrated serial port died with T30 and A31p, it's still available on dock for most newer ThinkPads:

Order with Serialized PTO Item with IB reference and Serial Number

I want to get to Orders with Serialized PTO Item with IB reference and their Serial Numbers.
I would like to know how I can link sales orders to IB. I wrote the foll. sql query but I am not sure if this is accurate. I am fairly new to this.. so any help is appreciated.
SELECT DISTINCT oeh.order_number,
--oel.line_id, oel.ordered_quantity, mtl.inventory_item_id,

AND oel.header_id = oeh.header_id
AND oel.org_id = oeh.org_id
AND oeh.sold_to_org_id = cii.owner_party_account_id
AND cii.serial_number IS NOT NULL

You want instances that are at the customer site right (last transaction is shipping) or all the instances that have been shipped before no matter what the current status is. Instance could have been returned and shipped again and so on or just returned and disposed.The second question will yield more instances compared to the first one.

Problems with serial port synchronization.

Hello to all!
I have an oxygen analyser, the equipment has a serial port for communication, being based the communication on the AK communication protocol.
In order to request to the equipment that responds with the measured value, the following command in hexadecimal is sent: (02 78474B4FE20 03), obtaining like hexadecimal answer the following: (02 58474B4FE203220323038353030 03), in which it is included the measured value.
I need to have the measurement from equipment in a PC, using the AK protocol and the serial port. For this, I have made a (vi) that it writes the read measure command in the serial port, wait a time (150ms) and read the port, this way everything works correctly, but there is a problem and it is that the communication is very slow due to the delay between the writing and the reading.
If I eliminate the delay, the synchronization between the writing and the reading is lost, appearing readings of value 0. I think that is because the PC read the port and the analyser not yet has responded to the request from PC, and this happens in spite of using the options of synchronization of visa read and visa write vi's, (Do I/O synchronously).
I would need to design a (vi) that hoped that the equipment had sent the last data, and then it sends the reading request again, being able this way to make the communication more fast and to eliminate the erroneous readings.
I have attached two examples, first is (vi) that works well, but has the problem of being slow due to the delay, and the second analyzes the received message to know when this complete and then it writes another message of read to analyser, but it appears to me an error (ocurred AT sights read... Time out) after minutes.
I would thank any aid that somebody could offer to me.
Greetings and thanks!

I don't have a serial port connected on this machine at the moment (they are becoming rare on laptops!) but try this code as a starting place. I notice in your second example you are basing the read on receiving a specific string, in the one I've made you can set the bytes at port compare to a number equivalent in length. I haven't tried it, as I mentioned before, so I appologize for any errors in my code.

Thinkpad with serial port (RS232)

For my job I need a laptop with a serial (RS232) port.
I have the choice of the following laptops: Lenovo Thinkpad X230, X230T, T430, T530, W530.
Neither of them have a serial port, right?
I saw some mention of an adapter for the ultrabay slim bay, that would support an RS232 adapter.
Does that work for all the above mentioned models?
And if so, would the RS232 port work in the same way as the regular one? I need to program e.g. an Agilent datalogger with Labview to measure and recieve the measured data through the serial port.
Kind regards,
Rachel.

thare are two ways :
1. you can buy a usb to seial cable converter.
2. if your laptop have a Docking Station. there is a serial port in the Docking station. Put your laptop on the Docking station, the windows system will automatically recognizes the serial port.
For example, my laptop is thinkpad x61t, Itself does not have any serial port， But there is a serial port on the Docking station.
I am a volunteer, don't work for Lenovo. I am a software engineer.

Programmig with Serial ports

Iam trying to send a message from my PC to a simulator through serial ports.Does anyone help me how can i proceed?

check out the javax.comm package and documentation, it has some sample programs for sending and recieving on the serial ports. Be careful with the installation, there have been some threads about this lately, but some of the files need to be installed in c:\program files\jre or similar, you can search the forum. Hope this helps :)

Looking for 17 inch tecra with serial port

Pretty sure there are no 17" Tecra models.

Is there a Labview Chroma6310 driver that works with serial port instead of GPIB?

The driver that I have downloaded from NI site is based on GPIB, I need to run it via serial port. I don't have GPIB board. I am pretty new in NI world. How easily can I convert the GPIB driver to serial port (ASRL)? Has anybody already done this? Any help on this is highly appreciated.
Best regards,
Farsh

I haven't looked at the driver and I'm not familiar with the instrument but the conversion should be pretty simple. If it uses VISA for the GPIB communication, the conversion is already done. VISA works with both GPIB and serial - just use the name of the serial port as the VISA reference name. This would be ASRL1 or Com1. If it's an older driver with the traditional GPIB calls, then replace every instance of GPIB Write and GPIB Read with VISA Write and VISA Read. You might also have to add some line terminator like CR/LF to every write. There are a lot of instrument drivers that are compatible with both serial and GPIB. The HP34970 is one that comes to mind. You might want to look at it to see how to do it yourself.

Get Serial port description With out Visa Intrument

Hi All
How can i get the description of a serial port ? eg. Communications Port (COM14)
I currently use the VISA Instrument but there is a big over head for the release, 65mb over head.
I would like to list all the available port for the user to select.
Thanks

You may find useful resources in this code published by Martin some time ago. Original code returns only the port number, but running it step-by-step you can find the point in which the text description of the device is found and use it.
