I have developed Utility which worked like Windows hyper terminal utility.
This Works very finly
HyperTerminal is a program that you can use to connect to other computers, devices and host computers.
HyperTerminal has capabilities beyond making connections to other computers and devices. It can, for example, transfer large files from a computer onto your portable computer using a serial port rather than requiring you to set up your portable computer on a network. It can help debug source code from a remote terminal. It can also communicate with many older, character-based computers.
HyperTerminal records the messages passed to and from the computer on the other end of your connection. It can therefore serve as a valuable troubleshooting tool when setting up and using your serial port. To make sure that your device is connected properly or to view your device settings, you can send commands through HyperTerminal and check the results. HyperTerminal also has scroll functionality that enables you to view received text that has scrolled off the screen.
