Typically, they were half duplex, meaning that they could not send and receive data at the same time. 典型的,他们是半双工的,这就意味着他们不能同时发送和接受数据。
Simplex: Data communication in one direction only. Contrast to Full duplex, Half duplex. 单向:数据只作一个方向的传送。有别于全变向，半变向。
However, half duplex is undesirable because the signaling scheme is inherently full duplex. 然而，半双工模式不是我们所期望的，因为这些讯务机制本质上就是全双工的。
