しかし、その場合所望速度での発呼指令後相手との交信
がうまくいかない場合に気がつかず装置を放置すること
がある。However, in this case, if communication with the other party does not go well after issuing a call command at the desired speed, the user may not notice and leave the device unattended.
本発明は以上の欠点を除去するものでモデム制御手順後
の伝送速度を表示させかつ自動的に速度変更を可能にす
ることにより、回線の状況を容易に把握でき、交信不都
合を生じさせない。The present invention eliminates the above-mentioned drawbacks by displaying the transmission speed after the modem control procedure and making it possible to change the speed automatically, so that the line status can be easily grasped and communication problems will not occur.
以下添付図面に従って本発明の一実施例を詳細に説明す

、第３図、第４図のようなモデム制御手順を行う。1 is a personal computer communication control device main body, which is connected to the personal computer 10 via the RS-2320 interface section 2;
It is also connected to the communication line 9 via the NCU 9. C.P.
U4 connects personal computer 10 and communication line 9 by program firmware stored in ROM3.
In response to commands from the personal computer 10, a call origination sequence and an incoming call sequence are started via the modem 7 and NCU 3 of the modulation/demodulation section, as shown in FIGS. 2, 3, and 4. Perform appropriate modem control procedures.

コンデータがその速度で送られる。Figure 2 shows the procedure before starting data transmission when a transmission rate of 2400 bps is selected.
The bps modem mode is sent as an MCI signal, and when the calling side receives this, it transmits the 2400 bps modem mode to the MF.
Send with I signal. When the called party receives this, it sends out a TCR signal, which means that the transmission rate of 2400 bps has been selected, the modem control procedure is completed, and the PC data is subsequently sent at that rate.

パソコンデータがその速度で送られる。Figure 3 shows when a speed of 4800 bps is selected, the called side sends a 4800 bps modem mode with an MCI signal, and when the calling side receives this, it sends a 4800 bps modem mode with an MFI signal, and then TCC. Send a signal. When the called side receives the TCC signal normally, it sends the TC
The R signal is sent, and therefore the transmission rate of 4800 bps is selected, the modem control procedure is completed, and the PC data continues to be transmitted at that rate.

のＭＦＩ信号を送出する。Figure 4 shows a case where 4800 bps is selected and then automatically switched to 2400 bps due to an inconvenience on the line, and the called side sends the 4800 bps modem mode as M (, I signal), and the calling side receives this. Then, the modem mode of 4800 bps is sent as an MFI signal, and then a TCC signal is sent.If the called side cannot receive the TCC signal normally, that is, the called side cannot obtain CC within the predetermined time from the MCI sending room. The TFI signal is sent on the calling side.
When the signal is received, it sends out an MFI signal with the modem mode set to 2400 bps.
着呼側はこれを受信するとＴＣＲ信号を送出し伝送速度
は２４００ｂｐｓとなりモデム制御手順は終了す゛る。When the called side receives this, it sends out a TCR signal, the transmission rate becomes 2400 bps, and the modem control procedure ends.

Ｉの判定に応じて表示する。There are three types of modem control procedures as described above, and after the modem control procedure is completed, the calling side transmits the transmission speed transmitted by the MFI to the display section 6 in FIG. 1 via the I10 interface section 5. In other words, in Fig. 2, a numerical value of "240" is displayed in response to a 2400 bps MFI signal, and in Fig. 3, a numerical value of 48 is displayed.
In response to the 00bps MFI signal, r480J is displayed, and in Figure 3, after r480J is displayed, 240J is displayed in response to the 2400bps switch.Also, the called party transmits the most recently received MFI signal. The speed is sent to the display unit 6 in Fig. 1 via the I10 interface unit 6. In other words, in Fig. 3, only the r240J of 2400 bps is sent to the receiving MF.
It is displayed according to the judgment of I.
