    The invention provides a serial communication adapter, which could provide physical communication port with an interface. The dispatch of a task with different priority level on the adapter could facilitate the key task on timeliness to be executed as soon as possible, in order to prevent data from losing. Data needing a communication port for being sent out or received is stored in a buffer of the adapter. And the data and order communication between the adapter and a host-based system is executed well on one DMA channel.
