The electrical channel used by the IBM AT and compatible computers to connect the computers motherboard and peripheral devices, such as memory boards, video controllers, PC card modems, bus mouse boards, hard and floppy disk controllers and serial/parallel input/output devices. The AT bus supports 16 bits of data in one slug, whereas the original IBM PC supported only 8 bits (and was called the ISA bus for Industry Standard Architecture). These days there are much faster buses, including the EISA, MCA (MicroChannel Architecture), Local Bus, PCI, VESA, etc. AT总线 ????? IBM AT以及兼容机使用该电子通道连接计算机母板和外部设备，如存储板、视频控制器、PC卡调制解调器、总线鼠标板、硬盘和软盘控制器以及串行/并行输入/输出设备。在一块小金属块上，AT总线支持16位数据，而早期IBM 个人电脑仅支持8位（工业标准体系称之为ISA总线）。现在又有了速度更快的“总线”，包括EISA、MCA（微通道体系结构）、本地总线、PCI、VESA等等。 AT Command Set ????? Also known as the Hayes Standard AT Command Set. A language that enables PC communications software to get an asynchronous and Hayes-compatible modem to do what you want it to do. So called AT because all the commands begin with AT, which is short for ATtention. The most common commands include ATDT (touchtone a number), ATA (manually answer the phone), ATZ (reset modem — it will answer OK), ATSO=O (disable auto-answer), and ATH (hang up the phone).To avoid having yourself knocked off your data call by the beep that comes in on the phone companys call waiting, put the following line in your modem setup: ATS10=20. That will increase your S10 register to two seconds. This register sets the time between loss of carrier (caused by the 1.5 s
