Abstract

PURPOSE:To facilitate the setting/alteration of the special specification of a 'TELEX(R)' by selecting a parameter table for specification setting for reference by means of a table selection key input during an online operation. CONSTITUTION:More than two kinds of specification are previously set and the parameter table generated at the time of setting them is stored in a parameter reference memory 6. When the alteration of special specification is required at the time of operating a device at an online operation mode, the parameter table which a processor refers to is switched by inputting a table selection key 8a, and the operation is started by new setting. In such a case, the alteration of specification is only the table selection key input, and simple switching can be executed in an online state. Thus, the setting and alteration of special specification is easily executed.

(Problems to be Solved by the Invention) By the way, the conventional telex terminal device having the above-mentioned configuration has a configuration in which, for example, various special operations can be selected during online operation. This includes, for example, setting the ANL (auto new line) transmission sequence, setting the answerback transmission state for WRU (W) 10 ARE YOtl), or setting the memory FDD.
There are settings for transmitting answerbacks from the floppy disk drive (floppy disk drive), etc. These special specifications were set as follows.

FIG. 2 shows a flowchart of a conventional telex terminal control method.

In the figure, first, when setting of special specifications is started (step S1), from step S2 to step S4, setting of ANL transmission sequence, setting of sending answerback to WRU, setting of sending answerback from memory FDD, etc. are selected by the operator. For example, regarding the above transmission sequence, the following settings are made: carriage return (CR) - line feed (LF) - carriage return (CR).

Further, WRU is set to on, and answerback of memory and the like is also set to on.

When such settings are completed (step S5), parameters based on these settings are generated by the processor 2 in FIG. This parameter is written to the EEFROM 6 in step s6.

When the setting of the special specifications as described above is completed, the process returns to the normal local operation mode as shown in step S7.

Then, in step S8, the system enters a waiting state for selecting whether to enter the online mode, and when the operator presses down the Ca1l key, the system shifts to the online mode.

In addition, when transitioning to this online operation mode, please make sure to
Parameters, which are the contents of the special specifications, are read from the EPROM 6 and written into the program RAM 4.

Next, the processor 2 refers to the program RAM 4,
The online state is established (step 510), and after that, the operation starts in the online operation mode from step Sll, and if there is a new change in special specifications after that, the process goes through the judgment step S12 and returns to the offline mode.
That is, the mode is switched to the normal local mode (step 31).
3) In this case, the switching is also done by pressing the Ca1l key again.

As mentioned above, in conventional telex terminal equipment,
When sending and receiving data online, be sure to first return to the offline state, that is, to the normal local operation mode, before setting or changing any special specifications that are required.
It is processed. Moreover, in the setting work, it is necessary to select the presence or absence of setting for each specification by pressing a keyboard or the like each time, and there is a problem that setting and changing the special specifications becomes relatively complicated.

The present invention has been made with attention to the above points, and an object of the present invention is to provide a method for controlling a telex terminal device that facilitates changing the settings of special specifications.
