原文说 The entire message frame must be transmitted as a continuous stream. If a silent interval of more than 1.5 character times occurs before completion of the frame, the receiving device flushes the incomplete message and assumes that the next byte will be the address field of a new message. Similarly, if a new message begins earlier than 3.5 character times following a previous message, the receiving device will consider it a continuation of the previous message. This will set an error, as the value in the final CRC field will not be valid for the combined messages. 我有点不明白的是： 如果在一个字符数据传送完后，中间有2个字符时间的停顿，那么在这两个字符停顿时间后传送过来的新字符按前面第一段中的描述，将作为新消息的地址段数据，可是若按英文中的第二段说明，又会与那2个字符停顿时间前的消息数据组合成一个所谓的消息。这不是自相矛盾的吗？ 谢谢各位！
