Hyper Terminal

what says communications theory? - transmitting info from one person to another? OR who says what to whom in what channel with what effect. It depends on the context being used. In terms of computers it could be as simple as connecting two devices.

HyperTerminal is an application you can use in order to connect your computer to other remote systems. It comes with Windows as preinstalled. Search your programs list if you could find it (hint: Communications). It allows to connect using modem, Ethernet, or serial port. I could possibly talk only about connecting a GSM phone to Hyper Terminal, coz i never connected modem.

When we connect GSM phone over a COM port say COM1, Windows automatically detects the phone and ask for COM port to use (if using IrDA then use COM4 since IrDA is mapped to serial on COM4). Then after setting the port settings like baud rate, data bits, parity and flow control etc, we are connected to the GSM phone. Use AT commands to test if it is really connected. At Basic level type AT on the Hyper Terminal screen and hit the return key. OK means successful response. When i had connected my SE w550, the first thing i did was to transfer a game (from getjar.com) to it and i did succeded.

You could also connect to a remote PC or your friends PC and try chat with him/her. Its like sending messages using net send commands.
