    Abstract: A data entry apparatus is described in which tabbing can be performed normally in one mode to enter tables row by row or vertically in another mode to enter tables column by column. In the particular embodiment described, data to be displayed on a CRT screen are held in a recirculating memory (80) used to refresh the screen. Tab stops are held in a shift register (102) driven in synchronism with the recirculating memory. When the tab key on a keyboard (1) is depressed, the cursor is displayed at the next tab stop to the right on the same line. When a coded tab key is depressed, the cursor is displayed on the next line at the nearest tab stop to the left. A tab character is displayed whenever the tab key (normal or coded) is operated.

    Abstract: The appts. includes circuits for receiving signals between the data processing equipment and the communications network. A digital processing circuit (12) controls the operation of the transmitting/receiving circuits in accordance with control code stored in a control store (24). A circuit (4) couples the equipment to the network. The appts. includes common hardware for a range of different network standards. The coupling circuit contains a circuit for identifying which network is to be connected to the equipment. The appts. is configured to the standard of a particular network when the coupling device is connected to the appts. A coupler for connecting data processing equipment to a communications network has a plug for connecting it to a standard communications socket and a connector for attaching the coupler to the data processing equipment. The coupler includes a standard identifier code corresponding to the communications socket for configuring the equipment to comply with that particular standard.

    Abstract: Keyboard apparatus is described in which a keyboard having dead-keys to enable accented characters to be entered is claimed. A storage means, preferably of read only type, is divided into a number of sections; each section contains character codes representing accented or non-accented characters associated with that section. When a given dead key is activated, this addresses a section of the store associated with that dead-key to access the section containing the characters which are accented with the accents associated with that dead key. Activation of the next character key causes accessing of the code for an accented character within that section. Different accents for the same or other characters can be associated with different dead keys. Optionally the store can be arranged to store only validly-accented characters, thus avoiding the entry of invalidly-accented characters. Non-accented characters are normally accessed from a single section of the store. Common accented characters do not require dead-key operation.
