空调制解调器电缆基本上用于两个RS-232 DTE设备之间的通信。若要在设备之间创建空调制解调器连接，您需要使用两台计算机或一台与空调制解调器电缆连接的计算机的两个串行端口。由于许多原因，上述两种方法都非常昂贵和困难。创建空调制解调器连接的最可靠方式是使用虚拟串行端口，由虚拟串行端口驱动程序和空调制解调器电缆模拟。为什么需要模拟串行端口和空调制解调器连接？这样做的主要原因很少。首先，您不需要使用真正的空调制解调器电缆连接两台计算机。其次，在一台 PC 中不需要具有多个可用串行端口和额外的多串行端口设备，这些设备价格昂贵且笨重。可以有效地使用模拟空调制解调器连接虚拟空调制解调器。该程序模拟一个或多个通过虚拟空调制解调器电缆连接的 RS-232 串行端口的一对。可以创建单个 PC 上的无限连接虚拟串行端口，并使用虚拟空调制解调器电缆按任何顺序连接它们。通常，当您有两个应用程序要通过串行端口连接时，您需要使用虚拟 null-modem。与普通连接相比，您不需要任何其他硬件（计算机、物理串行端口、电缆）来执行它。虚拟 null 调制解调器允许用户模拟虚拟空调制解调器连接，并在同一台计算机上同时运行两个应用程序。此外，通过向数据交换添加一些错误来模拟真实情况，这些错误可能发生在物理 null-modem 连接期间。由于其功能设置虚拟空调制解调器可以充分缓解软件开发人员和测试人员的工作占用在工业自动化领域。此外，该计划也可能在逆向工程以及教育需求中有用。所以，继续下载免费试用版吧！
