Conventionally, a large-scale communication system based on a large-scale host computer and a simple communication system on a single line by a small computer have been provided. Also, with the construction of a communication system using a small computer as a host,
When performing simultaneous control of multiple lines, it is possible to control multi-line communication by time division, but this is not practical because a large load is placed on the memory that depends on the OS (operating system). Therefore, in the data communication system for simultaneously controlling a plurality of lines, a multi-line communication system using a large computer as a host has been constructed.

However, in a data communication system for simultaneously controlling a plurality of lines, a system construction using a large computer as a host is expensive, lacks versatility, and is cost-effective and simplified. There was a problem in trying to build a small-scale system.

The present invention has been made in consideration of the above circumstances. For example, in data communication between a terminal device and a host, a small-scale multi-line communication system using a personal computer as a host computer is constructed to provide a system. The present invention provides a complex system processing device that simplifies the construction of the system, improves cost-performance, and improves services due to communication efficiency.
