我已经成功实现了Java Api并开始发送短信和拨打电话.但我发现无法接听来电.我已经尝试了RI事件(serialPort.notifyOnRingIndicator(true);).但是它没有触发只有DATA_AVAILABLE事件才会被激活

1. 我已经尝试读取输入缓冲区和On检测"RING"发送ATA命令但它无法检测RING,即使从InputStream直接写入Console时它包含RING
2. 尝试在串行事件处理程序中的FROM Case RI(Ring Indicator)时发送ATA命令.

我正在尝试实现一个IVR系统.如何在这种情况下发送ATA命令,如何检测RING以及为什么RI事件不会触发
