When transmitting data to the application program 4b in the other host computer lb, the communication control mechanism 5a in the sending host computer 1a receives a transmission request from the application program 4a (step 10.11) and sends an instruction. Transmission processing such as setting the address of the destination computer 1b and inserting a channel control command (first control command) for output to channel 12 into the header is performed (step 12), and then communication to the destination is performed. It is checked whether the route is a communication line or a LAN (step 13), and if it is a LAN, the protocol conversion mechanism 6a converts the conventional communication control procedure into a LAN control procedure (step 14), and sends it as the first control command. A LAN control command is inserted into the header as a second control command so that the LAN can be directly controlled for the transmission data for which the channel control command is set, and then output to channel 12 (step 15). The LAN control device 20a, which is directly connected to the channel 12 of the host computer 1a, receives and receives data from the host computer 1a according to the channel control command as the first control command, and connects the LAN 30 with the LAN control command, which is the second control command in the header. Send to. On the other hand, the LAN control device 20b directly connected to the host computer 1b on the receiving side receives the LA from the LAN 30.
The received data including the N control command is sent to the host computer 1b in accordance with the channel control command as the first control command from the host computer 1b (steps 10, 11.16).

That is, the LAN control procedure is converted into the conventional communication control procedure from the LAN control command, which is the second control command. After the conversion, the communication control mechanism 5b performs reception processing such as deleting the header including the address etc. on the received data (step 19), and passes the received data to the application program 4b (step 20).
