hi all,

i am relatively new to c++ programming.

would like to ask is it possible to write a program to invoke the hyper terminal?

in the sense the program will allow user to enter phone number(maybe plus some others parameters like data bits,baud rate) before it invoke hyperterminal?

plus can the program also input command to the hyperterminal which is connected to a modem to do some function?

pls help.
thanks.

Yes. It is possible. It is not overtly simple. In order to invoke Hyperterminal (a piece of junk, as terminal emulators go) you would:


In order to pass HT parameters, you would want to check to see if it takes commandline arguments, which I don't know and I don't have it on my Macbook, so I couldn't test it or tell you.

However, you could create and save a configuration file and then look at the contents of it so that you could produce your own configuration file and then invoke HT with the configuration file as a startup parameter, I think.

To send a running instance of HT some "commands," you would use FindWindow and SendMessage or PostMessage.

Better might be to simply control the UART yourself using Win32 directly. It involves a lot more coding, but you have much more granular control over what you want to do.

Perhaps better still would be to find/download a better terminal emulator that has a better API for programmer's use. There are freely available, open source terminal emulators such as Tera Term and modify the source code directly.

You could easily hack it to create a server socket that listens on a particular port and then performs the desired commands sent from your application.

There isn't much that you can't do with C++. It is incredibly powerful. However, with great power comes great responsibility.
