Top of list Index page Interrupt 0xAC service 0xA3: DEV_RECV_WAIT, Wait for received data Parameters AH ES:DI Waits for data received signal from Interrupt Service Routine. 0xA3 (=DEV_RECV_WAIT) Device handle from the IfaceHandle member of the DevUserDriver structure used at the DEV_OPEN_IFACE call. Return Value Comments DX = 0, AX = 0: Success DX = -1: Failure, AX contains error code 255: Insufficient memory to complete operation This function sleeps until a DEV_NOTIFY_ISR signal by the device's ISR indicates that received data is available. This function should be used in combination with the DEV_RECV_IFACE API within the user implemented receiver task. For more detailed description see How to add a user device driver/link layer interface Clib TCPIP.C implementation of this function: int Dev_Recv_Wait(DevUserIfaceHandle DevHandlePtr, int * errorcode); Related Topics Top of list Index page Example - Receiver Task Interrupt 0xAC service 0xA4: DEV_NOTIFY_ISR, Signal from ISR Notify the TCP/IP stack from inside of an Interrupt Service Routine that there is incoming data available and/or that the device has sent a frame successfully. Parameters AH 0xA4 (=DEV_NOTIFY_ISR) Page 152 / 400
BX CX ES:DI Number of available received packets Number of sent packets completed (provisional) Device handle from the IfaceHandle member of the DevUserDriver structure used at the DEV_OPEN_IFACE call. Return Value Comments DX = 0, AX = 0 This function should only be called from the device driver specific ISR. It can be used to signal a receiver task which is waiting at the DEV_RECV_WAIT call. In this case the number of received packets should be set in BX register. The current implementation does not support a transmit task. The sent packets count in CX is a provision for informing a transmit task about completion of packet transmission. For more detailed description see How to add a user device driver/link layer interface. CLIB TCPIP.C implementation of this function: int Dev_Notify_ISR( DevUserIfaceHandle DevHandlePtr, unsigned int rcvdPackets, unsigned int sentPackets); Related Topics Top of list Index page Example - User device ISR Interrupt 0xAC service 0xA5: DEV_GET_BUF, Get a buffer from TCP/IP stack Parameters AH CX ES:DI Get a buffer from TCP/IP stack's pre-allocated buffer for storing incoming data from this device 0xA5 (=DEV_GET_BUF) Number of bytes buffer required Output Parameter: Pointer to a variable of type DevUserBufferHandle where the user buffer handle is stored. (This value is for internal use.) Return Value Page 153 / 400
