Novell NetWare - SPX Driver - ESTABLISH SPX CONNECTION

BX = 0011h
AL = retry count
AH = watchdog flag
ES:SI -> Event Control Block (see #03810 at BX=0003h)

Return:
AL = status (00h,EFh,FDh,FFh) (see #03825) DX = assigned connection ID number

Desc: Attempt to establish a connection with a listening socket

Notes: There should always be at least two SPX ECB's listening to a socket, so that NetWare can perform its internal packet exchanges. The first fragment should start with a SPX header (see #03826). Fill in all destination addresses.. This function is supported by Advanced NetWare 2.1+
