Abstract

PURPOSE:To realize the display of an under-communication state with no addition of hardware by performing the blinking display of a cursor during communication. CONSTITUTION:A character processor contains a data communication means A to perform the transfer of data to other character processors. When a communication interruption is applied under such conditions, the means A gives an instruction to a cursor blinking means C to blink a cursor and starts the data communication processing. The means C blinks the cursor on a display device via a cursor display means B to show an under-communication state of data to an operator. When the data communication is over, the means A gives an instruction to the means C to discontinue the blinking of the cursor.

Description

[Detailed description of the invention] [Industrial Application Field J The present invention relates to a character processing device having a communication function.

[Prior Art] Generally, a character processing device is composed of a keyboard section 2 display section, an output section, a storage section, and a control section, and is used to manually edit characters using a keyboard and then print them.

Next, the operation of this embodiment constructed as described above will be explained with reference to FIGS. 6 and 7.

Note that in the following description, the details of normal document editing/type processing operations will be omitted here since they are well known. Furthermore, since transmission procedures such as communication protocols in communication interrupt processing are well known, their explanation will be omitted, and only the internal processing according to the present invention at the time of communication interruption will be explained.

Furthermore, since the details of the circuit such as the display are well known, their explanation will be omitted. However, the cursor blink/no-blink control is executed by instructing the cursor blink register GRR to set/reset.

When it is off, it is in the state of starting communication, so the process moves to step S2 and sets the flag COMJ to ON°°.In the next step S3, the cursor blink register CR-R is set to instruct the cursor to blink. is set to instruct the display drive unit DDU 20 to blink the cursor.

As a result, the display drive unit DDU20 blinks the cursor in accordance with the register CItJt (see FIG. 6(B)).

In step S5, it is determined whether data transmission has ended. The determination varies depending on the data transmission protocol. For example, in the case of a BASIC procedure, the end is determined by receiving an EOT code (end of transmission). If it is determined in step S5 that the process has ended, the process moves to step S6; otherwise, the interrupt process ends.

In step S6, the register CR-R is reset to instruct the cursor to stop blinking, and the display drive unit DDU20 restores the cursor blinking display (see FIG. 6, FC+).

In the next step S7, the 3M communication flag COM F
is set to “OFF” and ends the interrupt processing.

Next, some modifications and additional uses of the above embodiment will be described.

In the embodiments described so far, as shown in FIG. 6, an electronic typewriter with a one-line display has been described, but the present invention can also be applied to devices with a display of one or more lines. It is clear that it can be done.

Furthermore, in the above embodiment, the cursor blinks only during communication, but if the received document is
