Hi i try to send command to calc of openoffice ,i want send simple hello world in first cell, i try to call in this mode first i call
libreoffice --calc --accept="socket,host=localhost,port=2002;urp;StarOffice.ServiceManager
and after i try to connect netcat 127.0.0.1 2002 , it answer me e��'com.sun.star.bridge.XProtocolPropertiesUrpProtocolProperties.UrpProtocolPropertiesTid�H!�
but if i try to send something not answer, anyone know how to do that? thanks
You'll need to do a deep dive into the Universal Network Object protocol (UNO), which was created back in the wild days when OLE, CORBA, and other RPC-like standards were duking it out. See this for an example:
https://wiki.openoffice.org/wiki/Uno/Remote/Specifications/Uno_Remote_Protocol
There's lots more. Good luck.

I'm not even sure whether I've framed this question correctly. Let me explain my situation.
I have an Application hosted in a OpenVMS environment which is being accessed via Telnet. I'm in need to programmatically accomplish certain tasks.
So far I could send and receive messages using a C# Telnet Client. I am able to execute tasks by sending commands and receiving responses. But for one task, I have to edit a Form to change some information. The command looks like below
>modify page <page_no>
As soon as I enter the above command, the entire terminal gets loaded with this Form, I have to use page-down to go through the fields, press enter to edit the text and use Ctrl-Z to save it.
I'm not sure how to accomplish this task programmatically.
I'm not familiar with telnet or VxWorks. I'm not sure the above is a feature of Telnet or OpenVMS. Kindly help.
This should be easy to figure out thanks to the clear text of telnet :D It shouldn't matter what platform your target is running. All you have to remember is that special keys like ctrl-z or page down, are just chars in the data stream. Ctrl-z is typically 0x1a, and I am not sure what page down is off the top of my head, but here is how you can figure it out:
Get wireshark http://www.wireshark.org/ and install it if you don't already have it.
Start wireshark up and capture all traffic on your NIC that will carry the connection to the target.
Start a normal telnet session to the target and issue all of the commands (including the page downs and the ctrl-z).
Stop wireshark capture and then filter out everything except telnet communication between you and the target.
Look at the data that was sent to issue the ctrl-z, and page downs.
Put those chars in your telnet stream when you are ready to issue those commands.
Easy.
I am trying to find out how to use voice functions with a HUAWEI E173 dongle in linux.
My dongle is voice enabled (voice works with the windows application).
I can check the voice activation in linux using the AT^CVOICE? command.
This tells me how the raw audio stream should be organized.
From question How make use of the Voice API to make calls using Huawei 3g Modems? I understand that the idea is to
send commands on ttyUSB2 while passing raw audio data on ttyUSB1.
I also understand that stack overflow user https://stackoverflow.com/users/1043421/sai-chaitanya has voice working in Ubuntu in this way, so that this should indeed be the right approach.
What is completely unclear to me is how to dial out voice calls, to check if someone is calling and to answer voice calls.
Can anyone provide some clue or some pointer on this?
Thanks!
To do those, you need to use AT commands on the same interface as the one you entered the AT^CVOICE? command.
For example, dialing a certain number (+1 234 567 8888 in this case):
ATD+12345678888;
You see an incoming call on the terminal with the "ring" or "RINGING" indication. You can use 'ATH' to hang up or 'ATA' to answer.
Read more about AT commands, also called the Hayes command set here:

I have a string that I want to send to another computer that uses my software. I would like to send the string directly to the software in the other computer. Is there any way to do it?
other alternatives are to use tcp or udp broadcasts
If you need to send the string to multiple computers at once you can use a udp broadcast to 255.255.255.255 ; however with udp there is no confirmation of receipt.
Lots of examples are available if you search for them, here is one:

A standard way of achieving such task is to use Sockets. There are plenty of examples over the internet depending on the language and environment you are using.

I'm writing a GUI-based app in VB.net that talks to a LambdaMOO server via telnet, sends commands to display the object hierarchy, then parses the output and creates a visual representation of the object hierarchy.
So my question is: is there some kind of "telnet client" class for .NET to simplify the sending and receiving of data, or do I have to write my own using the socket API?
Does Mono have something like this?
Barring an easy solution, does anyone have a good tutorial they can point to for telnet client programming in VB.net?
Ok, I had a similar issue and ignoring all security complications and the like, wanted to TELNET from a VB initiated connection to a remote device and do stuff. I concur that the whole negotiation process is a hellish thing to do but once you've worked it out it's actually pretty simple to implement. I decided not to stop because I kept reading things that said it couldn't be done when it clearly can be done if you can write and read 1's and 0's into/from a network stream.
The code in the link below will initiate the connection and get you through to actually exchanging clear text information over TELNET. Given the example of sending a username and password combo shows how to read and write to the connection.
Big tips - initially have a nice big textbox or something to trap everything that comes into the buffer (variable returndata). This will help you diagnose problems. Also check on my blog there how to do this without the textbox blinking like a flashing thing. Once you've done all that and you know your script is reliable, trun off any screen updates and it will whizz through rather than take an age.
Apologies for the really dirty code and the crappy website layout.

The telnet protocol is basically just the usual TCP protocol, with a bunch of optional stuff that you probably won't need to implement. So you'd open a socket and start sending and receiving data with the socket stream interface.
Give it a try with the regular socket API, you'll probably find that it's quite straightforward.
just a suggestion. you may try to program your vb application to execute an existing telnet application in batch mode.
here is the link for your reference. refer to 7.3 Using Plink in batch files and scripts. Hope it helps.
You can grab one of any number of libraries to use. Here's one library:

For others try googling something along the lines of: library telnet mud .NET
Lastly, there are any number of opensource MUD/MOO/MUSH projects open at any time who are willing the share ideas and looking for people to help with projects.
I had my trials with telnet. You've to use tools like wireshark in conjuntion to figure out what commands needs to be initiated. I did find communicating with my unix box quite a challenge. For one thing you must know your telnet instructions. You might find it difficult to determined the state of the application - whether it is logged in or not innately. You'd have to formulate your own logic for it.
Another thing you'd have to do is parse the bytes returned by telnet into commands or instruction data i.e. you have to know if the bytes received is an instruction or some other thing it is trying to send you. Here is a ref that would come in handy.
First I suggest you start using the wireshark tool and get the communications send to and fro manually as well as via application.
From the LambdaMOO end of things, if you have wizard access or are friends with someone who does, you can have the MOO give you the data over another protocol that you might be able to work with more readily, such as HTTP. All you need is an object on the MOO with a do_login_command() set to handle requests, and then use the listen() builtin to get that object to listen on a given port. As long as a protocol doesn't require anything complex SSL, it's fairly easy to code up on the MOO end. So that might be worthwhile if VB.net has easier handling for HTTP etc.
im trying to read the current position of GPS Device...using N95 from Nokia.
I read tht i will need my device to return the NMEA lines to the serialport and then i will parse/split it to get things I want but all along I dont know what to write to the serialport to make device return the NMEA ?
Like There are other commands of AT for messaging etc...Is there any specific command to send to serialport to get NMEA ???
I found this site site which seems to guide you through everything you need to do.
I am not sure how it works in the N95, but in my HTC phone you cannot send commands to the GPS device to have it behave in a certain manner. Once I am connected to the serial port that the GPS device uses I can read a stream of data coming from it, which happens to be NMEA data. There is no way that I have found to send commands to the device to tell it how to behave.
I haven't used that specific GPS device before, but for mine, I just have to open the port and I start receiving the NMEA data immediately.
I have an N82, and as far as I know it doesn't speak NMEA directly. I use a script from this page - specifically one the titled "# Turn your S60 phone with an internal GPS (eg your N95) into a Bluetooth GPS" - to get NMEA strings.
Ahh oki so I need to run some script.Oki I think i should buy a specific GPS Device for it.
Which device will do my job in cheapest manner ?
I've never worked specifically with the N95, but most GPS devices will just start spitting out NMEA as soon as they're powered up, regardless of whether or not they have a lock. I don't know how the N95 is designed, but I'll bet it probably wasn't designed to give you access to the raw NMEA data from the GPS. You'll probably need some pretty fancy trickery to get it to do that.
If you don't need to use the N95, you might find it easier to just get a GPS module and use that instead. I've always purchased mine from SparkFun. They have some good evaluation boards boards and tutorials to help you get started.
A great way of doing this in Java ME is to use JSR 179: the Location API. Your app needs to create an implementation of LocationListener, then set it on the default LocationProvider. When your listener's locationUpdated method gets called, call:
location.getExtraInfo("application/X-jsr179-location-nmea");
This will provide access to the NMEA sentences.
You can send this over a serial port by using the Java ME commports mechanism (use:
System.getProperty("microedition.commports");
as described here).
Hope this helps,
