新兴的WINModem和Software Modem正在向硬件Modem发起挑战。 Modem在硬件架构上主要包含两个部分:数据泵即Modem的主芯片,完成数据的编码和解码的功能;控制器主要完成数据的纠错压缩,基本数据传输协议等功能,另外响应AT指令。软件Modem通常为将上述的两部分硬件通过软件实现,WINModem有DSP,但没有控制器,其功能通过软件实现,现在计算机的最低也是MMX166,所以使用WINModem在以后的机器不是问题。 WINModem顾名思义为WINDOWS Modem,通常只在WINDOWS操作系统下使用,但跟普通Modem功能一样具有数据收发、传真等功能。它的三
Emerging WINModem and Software Modem are challenging the hardware Modem. Modem hardware architecture mainly consists of two parts: the data pump that is the main chip Modem, complete data encoding and decoding functions; controller to complete the data error correction compression, basic data transfer protocol and other functions, the other in response to AT commands. Software Modem usually through the software to achieve the above two parts of the hardware, WINModem has DSP, but no controller, its functions through software, the minimum is now the computer MMX166, so the use of WINModem in the future is not a problem machine. WINModem as the name suggests WINDOWS Modem, usually only used under the WINDOWS operating system, but with the same function as normal Modem send and receive data, fax and other functions. It’s three
