Abstract: A brief introduction to the basic hardware structure of an ATM network interface card based on the integrated chip IDT77211 is given. The ATM NIC driver’s protocol stack, the main structure of PNA of PSos and the main modules of the software are given , with emphasis on the software modules of initialization, send, interrupt and configuration. The paper ends with the test results of the driver in three methods. The results show that the driver works well.
