Hola!!!Yesterday, I asked a question about serial port comunication, because I wanted to find a function in Labview similar to "ProcessSystem Events" in Labwindows!!
My problem is that I have written a comand through the serial port, and I doesn´t receive the answer. If I execute the programm step by step, I don´t have any problem but if the program runs i don´t get the answer!!!It is not a problem of the bytes that I write and receive, i have used the function "Visa Bytes at Serial Port"!!I have used th function "wait" but it doesn´t work!!!!i have used a Flat sequence but it hasn´t solved the problem!!so, i don´t know what i can do!!!
I attach the "different versions" that i did, maybe someone find a solution!!
Dennis, I have the problem, when
I read the last time in the program, I don´t receive the answer!thank you!!!
Gracinda

Dear Mads;
Thank you for your answer.
I don´t have a termination character but I know the number of bytes that I have to receive. I tried checking the number of bytes that I received, using "Bytes at Port", but it gets a value and it isn´t refreshed, it has a value so my program stop in the while structure that I have added. I attach the vi. I don´t know how to do that. I am starting with Labview, and it is a little difficult for me!!
In the first change that I did, I added the function "Bytes at Port" inside the While loops, but it doesn´t work either !!!
Thank you!

I am trying to ask the following question: Just updated my iPhone5 to V 7.1.2 and can no longer print to my MFC 7860W from this phone. I researched this issue on this forum and found answers from last October/November..... Wary of downloading anything that was posted that long ago. Wondering if there is anyway around this issue, with more recent information? I was able to use this printer in the past by using Brother's iPrint App.
Thanks!!
But when I hit post, I get an error message at the top - "you are not allowed to change this content" Can anyone help me?I am assuming you got that message when attempting to post an old thread. The old post is probably locked/archived.
FYI, posting on old threads usually yields no responses at all.
I have requested that this post be moved to the iPhone forum where you might get assistance.

Hello ,
I want to ask some question about ipads \
How powerful is the iPad?
How useful is it for reading books, newspaper or magazines or for surfing the web?
Can you identify any shortcomings of the device?
please help meit's less powerful than your average computer. THink of it like a netbook but with a better processor.
It'll do fine for surfing (although if you browse a lot of flash based sites you will need to get a third party browser since safari doesn't accommodate it)
You may do OK on reading books, papers or magazines, especially if they have apps, but the ipad's screen is backlit, so it doesn't work well outdoors and you may need to fiddle with the brightness so that you don't get eye strain (it's just like doing too much reading from a computer screen)
I would say the biggest short comings are data transfer. Apple's preferred work flow is that everything is done via iTunes or the internet....well people dont' always have 100% reliable always on internet access so you can find yourself in a situation where you can't get things on/off the iPad.
By and large, it's a good device for day to day stuff, but is not a computer replacement. -
I want to ask the question about phasor measurement.
I want to ask the question about phasor measurement.the first one is that how can I accomplish the sychronized sampling with GPS?The other question is that how can I adjust the sampling rate for DAQ when the system frequency alter continuously.(if I used the DFT,due to the altering of frequency,I can't get the completed waveform)"
Synchronising DAQ with GPS depends on the DAQ sampling rate. If the rate is higher than 2 Hz you can sample the 1PPS pulse of your GPS receiver together with your data.
You change the sampling rate with the AI Clock Config.vi. You cannot do this on the fly so you must stop DAQ with AI Control.vi reconfigure the sampling rate and then start it again.

i probably shouldnt say this but,okay i just recently asked a question.about my factory unlocked iphone 3gs asking how to activate it. so i got too excited of aving it and couldnt wait for my tmobile sim card to come one more day. so i "hactivated" it (i know this voids all warrenty) and i jailbroke it just so i could use it as an ipod.it worked and i was syched.
BUTTT.... it asked me if i wanted to update the software to 5.1 and i was like " oh yes id love to" and it started downloading it and it was inrecovery mode the whole time .
when the download finished. i hit restore so i can put the software on the phone but the itunes had an error and the phone went glitchy and it does a rebooting loop. it shows the apple symbol with the slash through it for about 5 seconds and shuts off for a little bit (about another 5 seconds) and it starts up then loops the process. ive managed to turn the phone off but if i start it up it loops...what should i do? any help :/
Also it does not show up in my itunes because it is turning off to fast to detect.Discussion of hacked phones is prohibited on these forums. Sorry, you'll need to go elsewhere to get support for a j'broke iPhone.

A question about opening ports
I have a question about opening ports with the airport. I need to open up ports UDP 88 & 3074 and port TCP 3074. I am wondering if I should open these ports for the specific IP address on my network that will be using them or if I should open the ports on the gateway IP (10.0.1.1) not sure which is the right route to take. Any help would be appreciated.
These are for running an xbox over xbox live.Typically, you will want to open these ports for the device on your local network that needs to be accessed from the Internet. In this case, it would be your Xbox 360.
Unfortunately, the AirPorts are not listed as Xbox Live-compatible routers ... so there is no guarantee doing this will get Open NAT status for Xbox Live.
The following web blog does a great job explaining the NAT issues with Xbox Live. Basically what it comes down to is that although you can get an Internet connection for the Xbox 360 with the AirPorts, you may not get the necessary NAT setting (Moderate or Open) for the Xbox Live game that you want to play. As such, Port mapping may be required to allow Xbox Live access.
The following ports must be available for Xbox Live to operate correctly:
• UDP 88
• UDP 3074
• TCP 3074
To setup port mapping on an 802.11n AirPort Extreme Base Station (AEBSn), either connect to the AEBSn's wireless network or temporarily connect directly, using an Ethernet cable, to one of the LAN port of the AEBSn, and then use the AirPort Utility, in Manual Setup, to make these settings:
1. Reserve a DHCP-provided IP address for the Xbox 360.
Internet > DHCP tab
o On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
o Description: <enter the desired description of the host device>
o Reserve address by: MAC Address
o Click Continue.
o MAC Address: <enter the MAC hardware address of the Xbox>
o IPv4 Address: <enter the desired IP address>
o Click Done.
2. Setup Port Mapping on the AEBSn.
Advanced > Port Mapping tab
o Click the "+" (Add) button
o Service: <choose the appropriate service from the Service pop-up menu>
o Public UDP Port(s): 88, 3074
o Public TCP Port(s): 3074
o Private IP Address: <enter the DHCP Reserved IP address for the Xbox you created earlier>
o Private UDP Port(s): 88, 3074
o Private TCP Port(s): 3074
o Click "Continue" -
Satellite P850 - question about Infrared port
Hi,
I have Windows 8 Pro installed onto my laptop and I've downloaded all the drivers and everything is working fine apart from the Infrared. I've searched all over the internet and I can't find a remote control to use with this laptop (including the Toshiba website).
I've installed the latest ENE CIR Driver (v4.1) as well as the Toshiba Remote Control Manager (v3.1.0.1). I looked in Program Files to open the Toshiba Remote Control Manager however when I click on the program to open it... Nothing happens (including in the notification area).
So my question is can I actually get a remote working with this laptop at all and if not then what is this Infrared port for because I can't find anything on my computer to actually use it with/for?!
Thanks for your help :pHi
Some Satellite P850 models are equipped with the remote controller and its possible to use the remote controller with Windows Media Center to play discs or videos, to view pictures and to watch recorded TV programs.
Models which dont include the a remote controller are *NOT* equipped with the an infrared receiver so the notebook cannot be operated with a remote controller.
The remote controller was not part of the package so your notebook does not support infrared receiver and therefore the installation of ENE CIR Driver and Toshiba Remote Control Manager was useless -

recently i designed a voice over ip , about 40 GW, 2 GK,all are 26 routers, i want to implement GK redundancy, i can use alternate method to config GK, but i want to use Cluster using GUP protocol, but we haven't used GUP before. i asked many person, they don't use yet.
i want to ask a question
are there any successful H.323 network using GUP.
and how about it, reliable or smooth,
thanks!
jackGUP provides the following benefits:
1) Sharing the load across several GKs
2) Any single GK in the cluster can resolve an address for another member in the cluster
3) You can cluster up to 5 GKs in a cluster to address redundancy and scaling requirements
GUP is not suitable in an environment where a large number of endpoints are registered. -
