Deleting Characters from Terminal Screen

Deleting Characters from Terminal Screen

Q – Why can’t I delete characters from the terminal screen?

A – The host you are connected to has control of the characters displayed on your terminal screen. The host is expecting the cursor to be at particular positions on the screen based on the data that it has already sent to the screen. If you alter that screen locally, you potentially disrupt the interaction between you and your host in ways that the host can’t predict or control. That’s why you can’t delete characters from the screen. By the way, the same thing is true of most clients displaying information from servers. For example, you’ll find that you can’t delete characters on Netscape Navigator or Microsoft’s Internet Explorer.
