描述bug
Linux版本同步模式写数据后，再读不成功，卡死

重现步骤
1.设置串口信息，打开串口，设置串口为同步模式；
2.往串口写一段数据；
3.串口马上返回响应的数据；
3.sleep 500毫秒；
4.再读取数据，不能正常返回，卡死；

预期行为
正常读取串口返回的数据

运行环境信息:

操作系统: 麒麟 SP V10
编译器: inter i5

其他内容
Linux情况下 commThreadMonitor 这个线程处理函数，在同步模式下，在检测到有数据可读时，直接将串口中的数据读取了，导致正常读数据，在sleep一段时间后，没有数据可读取了，一直卡死，这个应该是同步模式不启动读取功能；
