I want to send messages from android phone by using putty. Is that possible?
AFAIK, the telnet interface that is available for the emulator does not exist for hardware. You may be able to find a third-party SSH server or something, though that is not really in-scope for StackOverflow.

I am developing a parental kind of App in which there is a requirement to block specific urls from all the browsers in the Device. I think this is an old question but couldn't find any solution yet on stack.
Do you have any working solutions. Assumption - The device is rooted.

I have two resources for you:
Since the device is rooted you can work directly with iptables. iptables will give you very precise control over all coming and going data packets. Check out open source projects like AFWall+ on GitHub for iptables in action.
If you want to be able to run your app on unrooted devices look into creating a fake VPN. You don't send any data to an actual VPN server, you simply use the VPN API to filter all the information coming and going. Check out Disconnect (whenever they actually share their open source code...) or OpenVPN which is what Disconnect builds on.
I have a task to integrate a Bluetooth device into my application. Now my requirement is very specific. The device has a specific communication protocol which relies on certain ACKs but I figured it would make my development much easier if there was a program that let me test communication with the device.
I was wondering if there was a program for Linux, or perhaps a simple Android program which let me communicate with any Bluetooth device with a series of pings using data I enter and simply log the responses.
EDIT: I might not have been clear enough in my question.
I have a scale that I need to integrate into my application, and the scale has a protocol similar to this:
Get a specific byte string from device
Transfer data
Transfer packet for disconnection
Receive acknowledgement for disconnect packet
Disconnect
Now when I have to issue a POST request from my application, I usually build a test script online so I can test if the POST works properly.
I was wondering if there was something similar I could do with the device.
Thanks
Your question is not clear enough. To communicate with a BT device, you need to know what profile your device supports. Depending on that, you can find a way in Android or Linux or windows to communicate with the device.
The simplest way is to open an RFCOMM channel from android/PC and transfer data to and from the device. For this the device has to support the serial port profile (SPP). If you want to do this in Android, look for the BluetoothChat example from google.
If you want to use a PC/mac/linux look at the Bluez python module. It's really simple to use. There are plenty of other options too..
I was looking for something like SENA BTerm. It lets me connect to any device and send whatever data I wish.
It is an extremely useful tool for testing my code.
http://www.sena.com/download/manual_bterm/overview.html is where you can find it.
Is it possible to send SMS from Android emulator to a mobile phone via a GSM modem connected to a USB port of computer ? If it is possible how can I do that
Thanks in advance!
You could do that but android won't detect it as a native antena, in other word, all functions from android to send sms or initiate a call won't work.
If the device is visible is /dev/.. You could be able to open it and send command trough serial. Unless someone wrote a driver so android can load it for gsm communication inside the emulator, my guess is that it's pretty useless.
Anyway, the emulator does have a way to test sms sending as far as I can remember, and if you really want to send sms trough your gsm dongle, It's probably a better idea to start writing a script using python for example. There is also a library that enable sms sending from linux, it might also work on other platforms.
Sending sms from python from computer:

Checking incoming sms for emulator android:

Sending sms between emulators:
http://xjaphx.wordpress.com/2011/07/07/sending-messages-among-devices/
And then it really depends on what you need. You didn't exactly said why you wanted to do that. You didn't say if you wanted to test sms messaging or wanted to send actual sms from computer. It's not really clear why you need android and the gsm modem at the same time.
Is there any way to send request from a server to an Android phone? Actually, I want to control an application (enable or disable some features of the application) in an Android phone by a server. Can I use the IP Address of the Android device?. Can anyone guide me.
Thank you!.
Much simpler way is for phone to contact server and ask should features be enabled. You could also use something like this http://code.google.com/android/c2dm/ but I'm not sure if this is an overkill for your use case.
If the above option is not suited for your case then you can create a simple service
for your application and then attach to application.
The service can be a thread which sends requests to the server with some time intervals that you find suitable and can check if there is anything to check and to do for the application.
And also can run in background.
All push services are usually implemented as well concealed polling. Phones on 3G networks usually sit behind NAT proxies and are not visible to outside world. The same holds for most wlan networks - so either use C2DM, or write your own service polling config information from some server provided by you
I want to send and receive information between Emulators in Android.i am using two systems and i have installed android in both the systems and i have to consider one emulator as server and another as client.Now i want to send data from one to another.Anyone knows regrading this please help me with some sample code.
What sort of information do you want to send between the emulators?
You can transmit SMS messages, or simulate phone calls, from one emulator to another using the target emulator's console port number as the number to dial. The Android Developer Site describes the process in more detail under "Sending a Voice Call or SMS to Another Emulator Instance"
If you want to transmit data, unfortunately Android doesn't currently provide any P2P or Instant Messaging APIs, so there's no generic technique available through the SDK you can use.
Your best alternative is to create your own server-based solution (or your own P2P API, though that might be a little more complicated).
Take a look at Java Socket.
