Data terminal for communicating over a telephone circuit. |
摘要 |
<p>A data terminal which enables a craft technician to communicate through a gateway processor to other computers includes a program language support library and an operating system which can receive a condensed form applications program and supplement the received program to create a fully executable applications program. This permits convenient downloading into the terminal over a conventional telephone circuit. Also disclosed is an improved interface through which a telephone circuit can be tested to determine if it is active and idle in a substantially non-invasive manner. Respective computer protocols can be entered in the terminal in association with telephone numbers of respective computers for automatic use whenever the respective computer is called. A limited display area of the terminal is controlled so that a larger page of text can be sequentially displayed through it as if the limited display area is scanning across the larger page of text.</p> |
