How do i clear the receiver and send buffer?

I am trying to communicate with the Votsch 3050 thermal chamber, with LabVIEW as the control software via serial RS232. In sending the required ASCII strings, there was no response from the chamber, yet no error.
The manufacturers indicate clearing the receive and send buffer using the the "PurgeComm(HANDLE hFile, DWORD dwFlags)" function in C, but offer no LabVIEW support.
Does any one have any ideas on how i can do this using LabVIEW? Any Information or VIs would be greatly appreciated.

@dsbuxi I have worked with many patient monitors. They often work in a client server setup. Data is not sent before you request it. And the communication has to follow a certain protocol. Your job will be to implement this protocol in Labview. This is not too hard, but it requires some reading to understand the protocol. I am not able to send you any code, but feel free to ask if you need some help regarding the protocol
And you may have to order or make a custom cable. But you will also find this information in the protocol description. Good luck

Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

How do I clear the bookmarks and history on safari with ios 7 system?

I'm using safari on my ipad with ios 7.02 operating system. I've searched for answers in several places but no one seems to know how to clear the bookmarks and history on safari which show up below the address bar when you type in a new website address. Does anyone know how to clear this out? I've searched several places and others seem to have the same problem.

Click on the bookmark icon > Edit > Create a New Folder and call it whatever you want then
Settings > Safari > Favorites > select the new empty folder you just created.
To clear the history:
Settings > Safari > Clear History
or
In Safari click the bookmark icon > History > Clear

How do i clear the console

Hi Experts
I need to know "how do i clear the console " and
"how do position the mouse cursor in x and y coorditates in a console "
Thanks in advance

You don't. Or, it depends on the console. Depending on your point of view.
Java doesn't directly control it the same way that it controls an AWT window for example. It just sends bytes to it. If the console is capable of interpreting bytes in such a way to clear the screen, then it can.
Most consoles a person is likely to use will interpret VT100 commands. Look them up; try google. You can just output those commands and the console will do what they say, hopefully.
Sending a control-L (bye 0x0c, I think) may do it. Try that.
Or you can try the java curses library.
All this may be wrong if you mean something by "console" other than what I think you mean.

Ever since I updated my iPhone 4S and my iPad 2 to IOS 6 all my iMessages are coming to both my iPhone and my IPad. How do I stop the iMessages I send and receive on my phone from receiving on my iPad as well? I have tried going into my settings and making sure I'm only set up to receive iMessages to my cell number and not my email....but that didn't fix the problem.

Here the way to do it, for both, or for only one Go into your settings, Messages and turn on iMessage. It will then send messages that are iMessages to both your iPad and iPhone. You can also turn off this feature on the iPad if you do not want to receive messages on the iPad.

Message Driven Beans: how to receive and send in a single session?

Hello
How to receive and send JMS messages in a message driven bean using a single session?
Thanks.

Are you referring to writing code within the onMessage method itself to receive JMS messages?
If so, that is not a pattern that is recommended, especially not in the case of a blocking JMS
receieve. If you must write an explicit JMS receive within an EJB component it's best to use
a "check the queue" approach where you give a very small timeout for the receive. That way
if the message is there it will be returned but if not the call will not block.
You'll also need to take the transactional settings of the onMessage method into account.
If your are sending a message and then waiting for a response, those two actions can
not be done within the same global transaction. For that, you'll need to either use
BMT and perform each in its own transaction or just not use global transactions at all,
in which case each send and receive operation will be atomic.
