Hayes(賀氏 / Hayes Microcomputer Products)是一家美國調製解調器(Modem)製造商,該公司以 Smartmodem 聞名,Smartmodem 引入了一種控制語言,用於通過串行接口操作調製解調器的功能。 這種智能調製解調器方法極大地簡化了自動化操作。至今幾乎所有調製解調器都使用Hayes命令集的變體。在 1990年代中期,ADSL 和電纜調製解調器的廣泛採用,令到 Smartmodem 生意下滑,雖然公司在 Chapter 11 中獲得保護,但終於在 1999年被清算。Hayes(賀氏 / Hayes Microcomputer Products)外置(External)調製解調器(Business Modem Voice Data FAX),型號是 Optima 288 V.34 / V.FC + FAX + VOICE(5310HK),Optima 288 是一台商用調製解調器(Business Modem Voice Data FAX),功能非常多。
