2. Description of the Related Art In recent years, information processing devices have been made smaller and lighter, and those operating on a battery have been commercialized.

In many information processing apparatuses that operate on battery power, sleep processing and resume processing are performed in order to save battery consumption.

The sleep process is a process of shifting the information processing device to a power saving mode when a condition such as no key input for a predetermined time is satisfied while the information processing device is in operation. In addition, the work interruption information such as the display contents and the processing status at that time is stored in the storage device built in the main body such as the hard disk and saved.

Further, the resume process is a process for returning the state of the information processing apparatus to the state immediately before the transition to the power saving mode in response to an instruction from the user in the power saving mode. The work interruption information stored in and saved in is read.

[0006] In particular, if the storage device for storing the work interruption information is a non-volatile storage device, the information processing device can be powered off in the power saving mode.

For example, the electronic desk calculator disclosed in Japanese Patent Laid-Open No. 2-294760 is equipped with an auto power-off section for cutting off the power when there is no key input for a predetermined time. Before turning off the power, the unit performs a sleep process of storing the display content in the non-volatile memory and saving it, and when the power is turned on again, the display stored in the non-volatile memory is saved. Resume processing for reading the contents is performed.

In the following description, "connection" means a connection via a logical network line 50, that is, a logical connection.

Now, the operation procedure of the user of the information processing apparatus 10 up to this state will be described.

The user first activates a program (hereinafter, referred to as a window manager) that operates on an operating system (OS) and controls each window. When started, the window manager displays an icon corresponding to each emulator provided by the information processing device 10 and which is a program that can be connected.

For example, when the user gives an instruction to select the icon A, the window manager activates the emulator A corresponding to the icon A and opens the window A.

Then, the user inputs the command "telnet host A" on the window A, inputs the user name and the password, and logs in to the emulator A to the host A (20). Can be connected. Similarly, the user selects the icon B and selects "teln" on the window B.
By inputting the command "et host B" and logging in, the emulator B can be connected to the host B (30). In addition, for example, the user displays, for example, "rl" on the window A corresponding to the emulator A logged in to the host A (30).
The emulator A can be connected to the host B (30) via the host A by entering the command "login host B" and logging in. In addition to this, the command for connecting to the host includes "ftp" and the like.

The window A (301) shows the host name of the host A (20) connected to the emulator A, and the window B (302) shows the host B (30) connected to the emulator B. The host name of is displayed.

The display of the host name is performed by the emulator A and the emulator B, respectively.
In the XWindows system, it can be set as an option when the emulator is started.

FIG. 1 is a hardware configuration diagram of the information processing apparatus 10 of this embodiment.

In the figure, 101 is a CPU, 102 is a bus memory control unit for performing memory access control and bus control, and 103.
Is a main memory, 104 is a system bus, and 105 is various I / Os.
I / O bus connecting O devices, 106 non-volatile memory such as hard disk and flash memory, 107 other I / O devices such as keyboard and printer, 1
Reference numeral 08 is a network control unit for controlling connection, 109 is an input / output control unit for controlling vices by various I / Os, 110 is a display control unit for controlling display system, 111 is a display memory for storing display data, and 112 is A display unit such as a CRT or LCD.

The network control unit 108 connects to the host according to the instruction from the emulator.

The non-volatile memory 106 stores a sleep processing program, a resume processing program, mode information, work interruption information, and connection information, which will be described later, in addition to the OS, window manager, and emulator.

Instead of the non-volatile memory 106,
A part of the main memory 103 may be backed up. Further, the work interruption information may be stored in the floppy disk instead of the non-volatile memory 106.

By the way, the information processing apparatus 10 of the present embodiment shifts to a sleep mode which is a power saving state when a predetermined condition is satisfied during operation.

The predetermined condition is, for example, that there is no key input from the keyboard for a predetermined time,
It is conceivable that the processes of all the emulators being activated are not executed for a predetermined time, or the user inputs an instruction to shift to the sleep mode. However, the present embodiment is not limited to this.

FIG. 4 is a flowchart of a sleep processing program for shifting the information processing apparatus 10 to the sleep mode.

When a predetermined condition is satisfied, the sleep processing program is activated by the OS and first determines whether or not the information processing device 10 is connected to any host (step 401). .

If not connected, the contents of the registers and display data of each control unit at that time are stored in the nonvolatile memory 106 as work interruption information (step 404) and the sleep mode is informed. After storing the mode information shown in the non-volatile memory 106 (step 40
5) The power is turned off (step 406). Also, if you are connected, the command (including the host name of the connection destination) that was input to make the connection, the login information, and the emulator name that made the connection by executing the command. Is stored in the non-volatile memory 106 as connection information (step 402), and the host of the connection destination is disconnected from the network (step 403), and then the process proceeds to step 404.

For example, in the state shown in FIG. 2, in step 402, "telnet host A" and "emulator A", "telnet host B" and "emulator B" are stored as connection information.

In step 403, the emulator may be executing processing depending on the conditions for shifting to the sleep mode. In such a case, like the conventional shutdown processing, Stop the running process and then disconnect from the network.

Further, the work interruption information includes the emulator name of the emulator activated at that time (or the window name of the window opened at that time).

In this way, the information processing apparatus 10 of this embodiment shifts to the sleep mode, but in this embodiment,
In the sleep mode, the information processing device 10 is powered off. Therefore, when returning from the sleep mode, the user needs to power on the information processing device 10. However, since the operation of turning on the power may be performed in two cases, that is, the case of instructing the return from the sleep mode and the case of the normal power-on. Are stored in the non-volatile memory 106.

Further, the reason for disconnecting the network from the host when shifting to the sleep mode is that the power supply of the information processing apparatus 10 is cut off in the sleep mode, so that the network control unit 108 is also supplied with power. It will not be done.

When the information processing apparatus 10 that has entered the sleep mode as described above is powered on, first,
S is started, and the OS determines the mode information stored in the nonvolatile memory 106. If the mode information indicates that the mode is the sleep mode, the mode information is cleared and the resume processing program for performing the process of returning the information processing apparatus 10 from the sleep mode is activated.

FIG. 5 is a flow chart of a resume processing program for performing processing for returning the information processing apparatus 10 from the sleep mode.

In FIG. 5, the process of reading the work interruption information and starting the window manager based on the read work interruption information is the same as the conventional resume process, and is therefore omitted.

The resume processing program, after starting the window manager, immediately before the information processing device 10 shifts to the sleep mode, based on the emulator name included in the work interruption information stored in the non-volatile memory 106. The emulator that has been activated is activated (step 501).

Next, the connection information stored in the non-volatile memory 106 is read (step 502), and based on the read connection information, it is determined whether the started emulator has connected to any host. Is determined (step 503), and if not, the process ends. If a connection has been made to any of the hosts, the host name of the connection destination obtained from the command corresponding to the emulator name of the emulator is displayed for each of the started emulators in the window corresponding to the emulator. With (Step 50
4) After executing the command corresponding to the emulator name of the emulator and transmitting the login information, the emulator is made to connect to the host of the connection destination (step 505), and the process is terminated.

As described above, according to the present embodiment, when the information processing apparatus 10 shifts to the sleep mode in the working state in which the emulator connected to any of the hosts is activated, When the information processing apparatus 10 is returned from the sleep mode, not only is the emulator started but also the connection destination host is reconnected, so that the user connects after the power is turned on. Since it is not necessary to re-enter a command for logging in or logging in again, usability and operability are improved.

Further, according to this embodiment, when the host which was the connection destination is reconnected, the host name of the connection destination is displayed in the window corresponding to the emulator making the connection. Therefore, when returning from the sleep mode, the user can easily know under what circumstances the work was interrupted.

The above-mentioned mode information, work interruption information, and connection information are actually stored in a mode information file 601, a work interruption information file 602, and a connection information file 603, respectively, as shown in FIG. , Are stored in the non-volatile memory 106.

The OS, the window manager, the emulator, the sleep processing program, and the resume processing program, respectively, also have an OS file 604, a window manager file 605, as shown in FIG.
The emulator file 606, the sleep processing program file 607, and the resume processing program file 608 are stored in the non-volatile memory 106, loaded on the main memory 103, and stored in the CPU 101.
Is executed by

For example, a software structure when this embodiment is applied to a UNIX system will be described.

In the UNIX system, a file is structured as a hierarchical tree structure of a file having a single node called a root. All nodes except the terminal nodes are files directories, and the directory is
It holds the file information (including the file name) of all files registered as elements there, and is used to position the file set by the path name in the hierarchy.

Therefore, when applied to the UNIX system, since the mode information is stored in the sleep processing program and referenced by the OS as described above, the mode information file 601 includes the sleep processing program and the OS.
To be registered in a directory that can be accessed during startup.

The work interruption information is, as described above,
Since the sleep processing program stores and the resume processing program reads, the work interruption information file 602
Causes the sleep processing program and the resume processing program to be registered in a directory accessible during startup.

The connection information is stored in the sleep processing program and read out by the resume processing program as described above. Therefore, the connection information file 603 is a directory accessible while the sleep processing program and the resume processing program are running. To be registered in.

The emulator name in the work interruption information may be stored each time the window manager starts the emulator. In such a case, the work interruption information file 602 has the above-mentioned structure. in addition,
Make sure the window manager is registered in a directory that is accessible during startup.

The connection information is stored each time the window manager inputs a command to each emulator and logs in, and is stored each time the connection is cut due to execution of the command. The existing information may be cleared. In this case, the connection information file 603 is registered in a directory accessible by the window manager and the resume processing program at the time of startup.

Further, in the UNIX system, there are a root directory and a home directory as directories having a special role.

FIG. 7 is a diagram showing the structure of a directory.

In FIG. 7, 701 is a root directory and 702 is a home directory.

The root directory 701 is a directory corresponding to a root node among hierarchical directories that give a tree structure, and is prepared at initialization.

The home directory 702 is a directory preset in the system as a personal operating environment for each user, and is set as a current directory which becomes the first operating environment when the user opens a session. .

Although the default value is set for the file information of the file registered in the root directory, the user can set the file information of any file in the home directory.

When the system is powered on and logged in, the system accesses the file registered in the root directory 701, and subsequently accesses the file registered in the home directory 702 of the logged-in user. .

Therefore, as shown in FIG. 8, the mode information file 6 for each user is stored in each home directory 702.
01, work interruption information file 602, and connection information file 603 are individually registered and rewritable at the time of shifting to the sleep mode, so that it is possible to cope with a difference in connection environment between users. As a result, confidentiality from other users can be maintained. Also,
The sleep processing program file 607 and the resume processing program file 608 are common to each user. However, if these files are also registered in each home directory 702, all of these files will always be stored when each user logs in. Since the priority is given, the resume process for each user is guaranteed.

Since registering a file in the directory is actually designating the position of the file by a path name, the sleep processing program file 6
07 and file 608 for resume processing program
Is one entity.

However, in FIG. 8, the work interruption information stored in the work interruption information file 602 does not include the above-mentioned emulator name.

That is, the mode information stored in the mode information file 601 and the work interruption file stored in the work interruption information file 602 are:
This is information necessary for the resume processing program to start the window manager when returning from the sleep mode. Further, in FIG. 8, reference numeral 802 denotes a window manager environment setting file, which is information necessary for the resume processing program to set the window manager environment after starting the window manager, that is, the sleep mode setting information. This is the information necessary to start the emulator that was started at the time of migration.

As shown in FIG. 8, by providing the mode information file 601, the work interruption information file 602, the connection information file 603, and the window manager environment setting file 802 as one resume processing file 801, The resume process can be centrally managed.

As a result, the sleep processing program automatically creates the resume processing file 801, and the resume processing program creates the resume processing file 80.
By accessing 1, it is possible to easily recover from the sleep mode.

By setting the host name of the connection destination as an argument during the resume process, the emulator can easily display the host name in the window.

[0083]

As described above, according to the present invention, the resume process is performed even when the sleep process is performed in a work state in which another information processing device is logically connected via the network. Then, it is possible to return to the working state in which the information processing apparatus of the connection destination is logically connected again via the network.
