将八比特串行传输数据转换为并行的四比特数据

1.由于本程序使用的DAO类，该类仅支持Access97的数据库。所以在使用本程序时必需是Access97数据库。 2.Access2000转换成Access97的方法是：打开Access2000数据库，单击菜单“工具数据库实用工具转换数据库到早期Access数据库版本”。-1. Since this program uses the DAO class, type only supports Access97 database. Therefore, in using this procedure is necessary Access97 database. 2.Access2000 converted into Access97 method is: Open ACCESS2000 database, click menu
