BX = 0003h ES:SI -> Event Control Block (see #03810,#03811)
Notes: Returns immediately; IPX attempts to send the packet in the background. This function is supported by Advanced NetWare 1.02+. This function is nearly identical to BX=000Fh, except that it always copies the source address into the IPX header assumed to be at the beginning of the first fragment

Format of IPX Event Control Block: Offset Size Description (Table 03810) 00h DWORD Link 04h DWORD -> Event Service Routine (00000000h if none) (see #03814) 08h BYTE in use flag (see #03812) 09h BYTE completion code (see #03813) 0Ah WORD (big-endian) socket number (see #03809) 0Ch 4 BYTEs IPX workspace 10h 12 BYTEs driver workspace 1Ch 6 BYTEs immediate local node address 22h WORD fragment count 24h var fragment descriptors Offset Size Description 00h DWORD -> fragment data 04h WORD size of fragment in bytes.
Notes: ESR is a far procedure that is called when the ECB has been handled. On call, the in use flag is zero if the ECB has been handled, non-zero otherwise. If the flag is zero, the completion code holds the result of the event.. The first fragment should start with an IPX header (see #03815). All fragments are concatenated and sent in one piece. Node address FFh FFh FFh FFh FFh FFh broadcasts to all nodes

(Table 03814) Values Event Service Routine is called with:. AL = caller's identity (00h = AES, FFh = IPX). ES:SI -> event control block. Interrupts disabled
Return:

Format of IPX header: Offset Size Description (Table 03815) 00h WORD (big-endian) checksum 02h WORD (big-endian) length in bytes of total packet 04h BYTE transport control 05h BYTE packet type (see #03816) 06h 10 BYTEs destination internetwork address 10h WORD (big-endian) destination socket 12h 10 BYTEs source internetwork address 1Ch WORD (big-endian) source socket
Notes: An IPX packet has the identical format as a Xerox Network Standard (XNS) packet. The application must set packet type, destination address, and destination socket; IPX/SPX set the remaining fields
See Also: #03810 - #03826
(Table 03816) Values for IPX packet type: 00h unknown packet type 01h routing information packet 02h echo packet 03h error packet 04h packet exchange packet (always use this one for data) 05h SPX packet (see #03826) 11h NetWare Core Protocol (also used by Service Advertising Protocol) 14h Propagated Packet (for NetWare), NetBIOS name packet 15h-1Eh experimental protocols
Note: Undocumented packet type 14h will cross up to 16 networks deep in all directions; as Aaron Martin of Origin Systems discovered, the first 64 bytes of the IPX data in such packets should be considered reserved, as IPX places the traversed server nodes there.
