Seagate硬盘
固件包含2个FLASH代码和许多支持的文件。两个FLASH代码已知是作为工厂代码和用户代码。工厂代码包含所有的串口诊断指令但不是AT接口指令。用户代码包含除了最小的一套串口诊断指令外的所有AT接口指令。In the ‘Availability’ column, a ‘F’, ‘C’ and ‘B’ indicate the command is available at ‘Factory Code’, ‘Customer Code’ and ‘Both codes’ respectively.
在“可用性”栏,“F”,“C”和“B”显示在“工厂代码”里的可用命令,“用户代码”和“共同代码”分开。
The following is a short list of some of the serial port commands:
下面是一些串口指令的简略清单:
