<PC 3 from the mobile phone 11 side
7, packet transmission to the side of 1>34> In FIG. 7, the personal computer 34 gives the mobile telephone device 11 an opportunity to transmit data to the personal computer 31 at regular intervals (so-called polling) by a timer. When the time counting period reaches the transmission cycle (step D1, "YES"), the command packet transmission request with the header B is output to the mobile phone device 11 (step D2). Then, a response to the command packet transmission request from the mobile phone device 11 side is received (step D3). Also, step D
If the transmission cycle has not been reached in 1 (“NO”)
The process moves to step D4.

At step D4, when the user operates the personal computer 34 to monitor the processing contents of the portable telephone device 11, a monitor display request is generated ("YE
S ”), the personal computer 34 sends a monitor packet transmission request with the header A to the mobile phone device 11 in order to have the monitor data held by the mobile phone device 11 side transmitted to itself as a packet ( Step D4a).
Then, a response to the monitor packet transmission request from the mobile phone device 11 side is received (step D4b). If the display request is not issued in step D4 ("NO"), the process proceeds to step D5.

Referring now to FIG. Mobile phone device 1
The monitor task 25 of No. 1 receives a monitor packet transmission request from the personal computer 34 (step C1) or a command packet transmission request (step C).
4) or waiting for a command packet reception request described later (step C7).

When the monitor task 25 receives the monitor packet transmission request (step C1, "YE").
S "), data is acquired from the monitor data buffer (step C2), and a header A is added to the acquired data to generate a monitor packet. Then, when the generated monitor packet is transmitted to the personal computer 34 (step C3), the process proceeds to step C4. The monitor data is generated by the monitor task 25 by a process not shown in FIG.

When the monitor task 25 receives the command packet transmission request (step C4, "YE").
S "), the data is obtained from the command data buffer (step C5). The data for this command is
The command data is generated by the communication control task 24 and passed to the monitor task 25 by inter-task communication. Further, in steps C1 and C4, the transmission request of the monitor packet or the command packet is determined by whether the header attached to the transmission request is "A" or "B".

Next, the monitor task 25 determines whether or not the data acquired from the data buffer is data for changing the communication speed or protocol settings (step C5a). The setting change data here is the communication speed (for example, 300, 600, 1200, 2) when the mobile phone device 11 performs serial communication with the personal computer 31.
400 bps), XON / XOFF, data length, number of stop bits, presence / absence of parity, etc. These settings are made to the COM port 36 (COM2).

Then, when these communication speed / protocol settings are transmitted from the communication control task 24 because they need to be changed from the defaults (step C5a, "YE").
S ”), the monitor task 25 adds the setting information to the header B (step C5b), adds the header B to the acquired data to generate a command packet, and transmits the generated command packet (step C6). . Then, the process proceeds to step C7. If the data does not include the information for changing the setting in step C5a ("NO"), the process proceeds to step C6.

Referring again to FIG. When the packet is transmitted from the mobile phone device 11 as described above, the packet is accumulated in the reception buffer on the personal computer 34 side. Then, the personal computer 34 confirms that there is a packet in the reception buffer (step D5, “YES”).
The packet is acquired (step D6), and it is determined whether the header attached to the packet is "A" (step D7).

At step D7, since the packet with the header A is transmitted to the personal computer 34 ("YES"), the personal computer 34 removes the header from the packet and displays the data content. It is displayed and output to 34a (step D8).

In this case, as shown in FIG. 1, the data for data communication or the data which the data communication task 23 has passed to the monitor task 25 is displayed on the display 34a as [Data].
Specific] is displayed. Also, monitor task 25
The information about the state of the mobile phone device 11 monitored by is displayed as [Log], and the monitoring data passed by the communication control task 24 to the monitor task 25 is [Low Spd S
erial Monitor] is displayed.

On the other hand, in step D7, the packet to which the header B is attached is transmitted to the personal computer 31 ("NO"), so that the personal computer 34 first sets the communication speed / It is determined whether the protocol setting information is included (step D7).
a). If the setting information is included (“YE
S ”), and the COM port 36 (CO
M2) is set. If the setting information is not included in step D7a (“NO”), step D
Move to 9. Subsequently, the personal computer 34 removes the header from the packet and outputs the data to the COM port 36 (step D9) to transfer the data to the personal computer 31.

Then, the personal computer 34 proceeds to step D8,
After the execution of D9, the process returns to step D5 and the above processing is repeated until there are no more packets in the reception buffer. When there are no more packets in the receive buffer (step D5, "N
O ”), the process proceeds to step D10.

<Packet transmission from the personal computers 31 and 34 to the mobile telephone device 11> For example, when the personal computer 31 performs data communication via the mobile telephone device 11,
A command for communication control and communication data are transmitted from the personal computer 31 side to the mobile phone device 11. In this case, the personal computer 34 receives the command reception request (control command data) for the mobile phone device 11 issued from the personal computer 31 (communication target personal computer) (step D1).
0, “YES”), the command data transmitted from the personal computer 34 and placed in the reception buffer is acquired (step D11), and the command packet of the header B is generated (step D12). Then, the reception request of the command packet is output to the COM port 35, and the mobile phone device 11
(Step D13). And step D1
Return to.

If the personal computer 34 does not receive the command reception request issued from the personal computer 31 in step D10 ("NO"), the process returns to step D1. Here, FIG. 6 is referred to. Upon receipt of the command packet reception request transmitted from the personal computer 34 (step C7, "YES"), the mobile phone device 11 performs a reception process (step C8). Then, the packet is acquired from the reception buffer, and the header attached to the packet is "B".
If it is, the header is removed and the communication control task 2
Transfer to 4. Then return to step C1.

As described above, according to the present embodiment, the monitor task 25 of the portable telephone device 11 converts the data output by itself and the communication control task 24 into a packet format when communicating in the monitor mode. Then, the communication performed via the second interface 21L is multiplexed, and the communication signal of the second interface 21L is passed to the monitor personal computer 34 via the interface box 28. Then, the personal computer 34 side refers to the header of the received packet to determine whether the data is the data destined for itself output by the monitor task 25 or the data destined for the personal computer 31 output by the communication control task 24. If the data is output from the monitor task 25, the data is read and monitor processing is performed. If the data is output from the communication control task 24, the data is inversely converted into a non-packet format and the personal computer 31 is used.
To output to.

That is, in the conventional configuration, the portable telephone device 11
However, even if the first and second communication interfaces 21H and 21L are provided, both of them are used for communication with the personal computer 31, so that the communication state cannot be monitored in real time. On the other hand, according to the present embodiment, the communication control task 24 and the monitor task 25 can be shared by multiplexing the second communication interface 21L, so that the communication state can be monitored in real time. Therefore, it is possible to more easily debug and inspect the communication processing between the mobile phone device 11 and the personal computer 31 than before.

Further, according to this embodiment, when a command packet reception request is output from the personal computer 31 side to the mobile telephone device 11, the personal computer 34 converts the command data into a packet format, and the mobile telephone device is converted. 11
When the monitor task 25 refers to the header of the packet received and determines that the data is output from the personal computer 31, the data is inversely converted into the non-packet format and output to the communication control task 24. Therefore, the control command data transmitted from the personal computer 31 side to the mobile phone device 11 can be reliably transferred to the communication control task 24 via the monitor task 25.

Furthermore, according to the present embodiment, the portable telephone device 1
When the communication control task 24 and the monitor task 25 share the interface 21L, 1 sets the communication rate of the second communication interface 21L higher than that in the normal communication mode when performing communication in the monitor mode. However, it is possible to prevent the communication processing speed on the communication control task 24 side from decreasing.

Further, the personal computer 34 uses the communication control task 2
If the header of the packet including the data output by the data No. 4 includes setting information regarding communication with the personal computer 31, the communication port is set according to the setting information. , Mobile phone device 11
