1、第 032 号及第 127 号(共 34 个)是控制字符或通讯专用字符，如控制符： LF（换行）、CR（回车）、FF（换页）、DEL（删除）、BEL（振铃）等；通讯 专用字符：SOH（文头）、EOT（文尾）、ACK（确认）等；第 33126 号(共 94 个)是字符，其中第 4857 号为 09 十个阿拉伯数 字；6590 号为 26 个大写英文字母，97122 号为 26 个小写英文字母，其余 为一些标点符号、运算符号等。注意：在计算机的存储单元中，一个 ASCII 码值占一个字节(8 个二进制位) ，其最高位(b7)用作奇偶校验位。所谓奇偶校验，是指在代码传送过程中用来 检验是否出现错误的
2、一种方法，一般分奇校验和偶校验两种。奇校验规定：正 确的代码一个字节中 1 的个数必须是奇数，若非奇数，则在最高位 b7 添 1；偶 校验规定：正确的代码一个字节中 1 的个数必须是偶数，若非偶数，则在最高 位 b7 添 1。 为了便于查询，以下列出 ASCII 码表：常用 ASCII 码对照表第 128255 号为扩展字符（不常用），如需要请下载：完整的 8 位 ASCII 字符表ASCII 码键盘ASCII 码键盘ASCII 码键盘ASCII 码键盘27ESC32SPACE33!34“35#36$37%386063?6465A66B67C68D69E70F71G72H73I74J75K76
