PC机和键盘部分通信命令字
PC机向键盘发出的命令共有10条，键盘向PC机发出的键盘响应共有7条。

当收到PC机发送的命令时，键盘一般要在20ms内回答“确认”。

置位/复位命令格式：
PC机发送：ED
键盘发送：FA
PC机发送：命令码
键盘发送：FA
“命令码”内容为：0x00－熄灭键盘指示灯。

0x01－亮“Scroll”灯。

0x02－亮“Num”灯。

0x04－亮“Caps”灯。

以下扫描代码为按键通码。

当一个键被按下或持续按住时,键盘会将该键的通码发送给主机;而当一个键被释放时,键盘会将该键的断码发送给主机. 根据键盘按键扫描码的不同,可将按键分为3类:
第1类按键通码为一个字节,断码为0xF0+通码形式.如A键,其通码为0x1C;断码为0xF0 0x1C.
第2类按键通码为两字节0xE0+0xXX形式,断码为0xE0+0xF0+0xXX形式.如Right Ctrl键,其通码为0xE0 0x14;断码为0xE0 0xF0 0x14.
第3类特殊按键有两个,Print Screen键,其通码为0xE0 0x12 0xE0 0x7C;断
码为0xE0 0xF0 0x7C 0xE0 0xF0 0x12.Pause键,其通码为0xE1 0x14 0x77 0xE1 0xF0 0xl4 0xF0 0x77;断码为空.
组合按键扫描码的发送是按照按键发生的次序,如按下面顺序按左Shift十A键:
①按下左Shift键;
②按下A键;
③释放A键;
④释放左Shift键
那么计算机上接收到的一串数据为0x12 0x1C 0xF0 0x1C 0xF0 0x12.
