hi
i want to send sms from gsm modem to a j2me application, for this to happen i have to send sms to a specific port in which j2me application is running.when i m trying to send sms from modem it doesnt go to application it goes to inbox.
is it related to udh settings if yes then how do i set port no in settings?if no what are the other ways.

Hi Vignesh,
Might be you can call ActiveX or DLL objects of the software installed for modem from LabVIEW, if it is unblocked.

How can I tell if my X301 has a gsm modem ?

I have recieved a X301 model and it has a place for a sim card under the battery. Does that mean that it has a gsm modem ?
I have a data sim card which I use with an external modem. How can I tell ? Or how can I connect via the sim card ?

please help me

Thanks so much; you just helped me fit together the last few pieces of this puzzle. I did a little more digging and found a [url http://support.webecs.com/KB/a375/how-do-i-configure-sql-server-express-to-allow-remote.aspx]knowledge base article that explains how to set a static TCP port. According to the article, SQL Server 2005 selects a random dynamic port on installation, and my experience bears out the fact that it does survive server reboots.
TheAvalanche wrote:
If you don't want that, make sure the SQL Server Browser service is running and connect to your SQL Server using the instance name, and not use a port in the JDBC-url.
BTW: I am not sure if jtds supports usage of the browser service, the Microsoft SQL Server JDBC drivers since version 1.2 (I think) do.It would appear that jTDS doesn't support the browser service, at least not by default, because I tried using the instance name rather than the port to connect (along with just about every other possible combination) and it didn't work. In my opinion, using a static port makes a lot more sense anyway, since you don't have to rely on the browser service, and you'll always know what port to set in your firewall exceptions. (For anyone out there wondering about firewall exceptions, in addition to the static port for the server, an exception has to be created for the browser on UDP 1434 if you're going to use it, which most programs apparently do.)
Once again, thanks for all the good information!

[SOLVED] Set up ZTE mf627 GSM Modem - almost there...

Hi eve!
I have this goddamn dongle that never worked...
I read alot of posts about it, tried installing usb_modeswitch and everything, but the device never showed up on NM.
Plus i saw a big change in the last year and logs show a very strange situation that it's not yet documented on any forum. In fact, i still can't understand how the hardware is abstracted now that HAL is deprecated... Kernel magic powder? Keel anyway, HAL was a bit junky ;-)
So when i stick it in, it first tell me
Apr 27 00:03:24 myhost kernel: usb 1-4: new high speed USB device using ehci_hcd and address 4
Apr 27 00:03:24 myhost kernel: scsi8 : usb-storage 1-4:1.0

Apr 27 00:03:35 myhost kernel: usb 1-4: USB disconnect, address 4
!! Then! The device automatically shut down and restart givin theese new messages:
Apr 27 00:03:40 myhost kernel: usb 1-4: new high speed USB device using ehci_hcd and address 5
Apr 27 00:03:40 myhost kernel: option 1-4:1.0: GSM modem (1-port) converter detected

Apr 27 00:03:45 myhost kernel: sd 9:0:0:0: [sdb] Attached SCSI removable disk
At this point one may think that HAL now see a new modem and dbusses NM to create a new connection through the frendly wizard... but it doesn't...
Plus i get a ZTE MMC Storage on my "Computer" that i can't "safely remove"
Error detaching: helper exited with exit code 1: Detaching device /dev/sdb

SYNCHRONIZE CACHE: FAILED: No such file or directory
(Continuing despite SYNCHRONIZE CACHE failure.)
STOP UNIT: FAILED: No such file or directory
So i tried usb_modeswitch with the setting i saw on http://ubuntuforums.org/showthread.php?t=1017630&page=3 and it just worsened the situation since it would only mound as an MMC once restarted.
HAL infos, gathered from the link above, made no difference...
lsusb give "Bus 001 Device 009: ID 19d2:0064 ONDA Communication S.p.A. ZTE MF627 AU" with various Interface descriptor ("bInterfaceClass 8 Mass Storage" and various "bInterfaceClass 255 Vendor Specific Class" , no modem though...)
Damn, i'm afraid that these dongles only work fine if you are a teenager with an unsure personality that needs to check her facebook profile every 5 minutes on a windlords svista...

F*#ç s>*t!!! You mean modemmanager is the opt depend for NM to bring up the modem?!!!
sorry... thought it was wvdial...
So cool! This gives ZTE mf627 full linux support out of the box ;-)
And even the MMC reader seems to work! WoW
Love you all guys!

Snow Leopard and GSM Modems (Vodafone)

I'm not sure if this is the proper place to post this, but I'd like to share my experience with GSM (GPRS/3G) modems and Mac OS X. The main reason for doing this is the fact that I wasn't able to find any related information for my issues on the web and I think I'm not the only one with those issues. Feel free to post any feedback here
Few months ago I started using a 3G modem with my Macbook Air. The service provider is Vodafone and the modem is incorrectly marketed by Vodafone on the web as a Huawei device (E169), but it is a ZTE K3656-Z modem (I'm not sure if the companies are different or if the hardware is, in fact, different, but the kernel module is definitely different :D).
The first thing that annoyed me is the Vodafone Mobile Connect application. The 'response time' between plugging in the modem and actually getting online is quite big, and I really wanted to get it out of my way. I'm not using any SMS functionality, so from my point of view, the application was totally pointless. When you plug in the modem, it acts as an external CD Drive. If the Vodafone Mobile Connect application is installed, it will automatically eject (unmount) the drive. Unfortunately,
this usually (not all the time, but quite often) generates a crash in diskutil (quite annoying).
But what annoyed me the most, was the fact that, when online, the Vodafone application was taking at least 35% of my CPU. Now, this is unacceptable Under normal load (Safari, Adium), this was quite acceptable. But under slightly higher load, the CPU was getting quite hot, causing the kernel_task to try to slow down the system (and cool down the CPU) by taking about 135% of CPU (according to Activity Monitor) and making the system unusable. Of course, another side effect was the cooler running at 6400 RPM, faster battery drain and generally, making the system quite unusable. My 1st Generation Macbook Air wasn't able to deal with all that
When I first saw the high CPU usage by the Vodafone application, I immediately thought of the old 56Kb WinModems Back then, it was quite a common practice to develop modems that would use the CPU to compress/decompress or process the data/sound in order to make the modem as cheap as possible, but inflicting a huge system slow down - Yes, I'm that old :P
Given that experience with those modems, I figured that the Vodafone application was somehow doing that as a 'user space module' Boy, was I wrong
So, this is what I did: First of all, you need to properly identify the GSM modem. In order to do this (no Terminal involved) is to set up connection using Vodafone Mobile Connect, then using the System Preferences, head over to Network and check the available interfaces (no, this is not a tutorial, but a guide :P ). You should see either a Huawei Modem or ZTEUSBModem/ZTEUSBATPort. Keep in mind the modem you have, then disconnect. At this point, you need to use the Vodafone application to change the PIN settings on your SIM card. Use the application (Preferences -> PIN) and disable PIN check. Now you can safely remove the Vodafone application
The second step is to install the proper modules/drivers/kexts for this. You can either get them from the web (at this point, you already know what modem you have) or you can use the packages located inside the Vodafone Mobile Connect application installer. To do this, simply use 'Show Contents' of the installer, then locate the packages (pkg) inside the Resources folder for your modem (the names are quite clear :P). Install that package and you'll have the modem drivers installed on your system.
Once the modem drivers are installed, when you connect the GSM modem, the external CD Drive will 'mount'. Eject it and wait a little bit (few seconds) until the SIM card is initialized and the modem is available. Go to System Preferences -> Network and add a new interface using ZTEUSBModem (not ZTEUSBATPort). Set it up as a Generic Modem, GPRS Modem and configure it with your provider settings (APN, username, password). Set the dial up number as *99# (you can find a lot of tutorials on the web about setting this up - the tricky part was installing the proper modules and disabling the PIN check). You may now connect.
The downside of this is the fact that you need to manually eject the drive when connecting the modem, otherwise you won't get the modem functionality, no SMS functionality and no PIN security.
The upside is a very quiet system (the fan runs at 2400 RPM as opposed to 6400 RPM), a fast one (I can't see any noticeable slow down at all) and better battery life time.
I'm not sure what is the effect on other systems, but my 1st Generation Macbook Air was totally unusable after few minutes of online time. Now it works perfectly
I really hope that this is useful for other people Feel free to ask any question, I'm aware that my 'tutorial' skills are quite poor :P

Oh, I forgot to mention: This works both on Leopard and Snow Leopard (tested on both systems). I've used the modem drivers located inside the Vodafone Mobile Connect installer (I couldn't find any ZTE modem drivers on the web).

How does airport work?

If I get an airport express, will I have a wifi network by just plugging it into the wall? How does it work?

Basically, yes. The AirPort Express Base Station (AX) is a wireless Internet router. By default, it will broadcast an unsecured wireless network with a Network Name (or SSID) of Apple Network NNNNNN. Computers, which are Wi-Fi enabled should be able to connect to this network.
To gain Internet access, the AX needs to be connected to an Internet Broadband modem via an Ethernet cable connecting the two.

Error On access gsm modem using smslib.jar

Hi,
I had a GSM Modem.

However, i need to use another java application to read the sms from the modem.
I encounter the message below when i run the application,

Hello,
I have a Huawei E398 GSM Modem running on the latest Arch linux.
Kernel 3.8.10, modemmanager 0.7.990-4, usb_modeswitch 1.2.5-1, usbutils 006-1.

Thanks for any help.

I had very similar or maybe the same problem.
My error was:
localhost dbus[324]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.ModemManager1.service': Unit dbus-org.freedesktop.ModemManager1.service failed to load: No such file or directory. See system logs and 'systemctl status dbus-org.freedesktop.ModemManager1.service' for details.
I enabled ModemManager.service
systemctl enable ModemManager.service
and started it
systemctl start ModemManager.service
That solved the problem.

Send SMS through GSM modem

Hello,
We have a requirement of sending SMS after PGI . Could anybody please help me on how to use GSM Modem to send SMS through SAP?

Hey, I can give you another tip. I am using a very reliable integration program. Its name is Ozeki NG SMS Gateway. I hope they dont cut my tip out, because this software is very useful and stable. You are also able to add this message sending function to different clients for example HP Openview or Sharepoint etc.
Sorry again, I did not intend to advertise or something like that.

Sony Ericsson GM29 GSM modem - RS232

Hi all,
I have "Sony Ericsson GM29 GSM modem" connected to my PC with RS232 cable.
please tell me if someone know the port setting to use with Windows HyperTerminal ?
if it works in Windows HyperTerminal i can finish my LabView application immidiatelly.
any help appriciated.
Regards
Mor

Thanks all for your messages.
until now (3 days) i can:
* read first SMS from my GM29 gsm modem
* i figured that i need to read all "Bytes in Port" after the Write Command.
i do that in While loop, each iteration i re-query the "Bytes in Port" and
read the port until "Bytes in Port" equals to ZERO...
its work fine ONLY IF i put "Wait Until Next ms Multiple" (1000ms) inside the while loop
if i dont do that i read again the same string from the port, its "too fast" , i dont know why its behave like this.
now the problem is :
the SMS message have some format like this -
+CMGR: "REC READ","+657577575757",,"05/09/30,10:59:44+12",145,4,57,8,"+6748480032",145,64
05E605D205DD00E805D52005DE0505205DD002005DE0505E805D705D5
0205DD002005DE051002005E205DD002005DE0D4205DD0020055D505DE05D4
i gues that its UNICODE ...
so i need to convert this UNICODE to real String .....
again any help is appriciated
back to work......
Thanks.

How do I work with FK in a data profile?

Hello People:
I am new in OWB tools and I have many doubts. Therefore, I would like to know if anyone can guide me a bit with the theme of FK and profiles.
How do I work with FK in a data profile?
If I have a table that has a FK to most of the tables, because it is like a parent table. What should I do to have that FK in the profile?
e.g.
- Table 1 FK Table 2
- Table 1 FK Table 3
- Table 1 FK Table 4
- Table 1 FK Table 5
- Table 1 FK Table 6
- Table 2 FK Table 7
- Table 2 FK Table 8
- Table 8 FK Table 9
You should have a data profile with each table or a data profile for all related tables?
If I am all in a single profile, that it would have no problem but I would only slow every time that I have to add a new table, but if I got separated, I can not use the FK? What is the solution that will give this problem?
e.g. PROFILE GENERAL
- Table 1
- Table 2
- Table 3
- Table 4
- Table 5
- Table 6
- Table 7
- Table 8
- Table 9
OR
PROFILE 1 -> - Table 1
PROFILE 2 -> - Table 2
PROFILE 3 -> - Table 3
PROFILE 4 -> - Table 4
PROFILE 5 -> - Table 5
PROFILE 6 -> - Table 6
PROFILE 7 -> - Table 7
PROFILE 8 -> - Table 8
PROFILE 9 -> - Table 9
OR
PROFILE R -> Table 1 / Table 2
PROFILE S -> Table 1 / Table 3
PROFILE T -> Table 1 / Table 4
PROFILE U -> Table 1 / Table 5
PROFILE V -> Table 1 / Table 6
PROFILE W -> Table 2 / Table 7
PROFILE X -> Table 2 / Table 8
PROFILE Z -> Table 8 / Table 9
Thank you very much for your help!
Best regard!

Any idea, please?
