Int 63 Fn 24  - Bw-tcp - Tcpip.sys - Get Socket                            [N]

   AH = 24h

Return: AX = socket number (0400h-FFFFh)
Range: INT 4D to INT FC, selected by configuration

Note:  the Beame&Whiteside TCP/IP protocol stack uses two consecutive
     interrupts (62h and 63h by default); the BW-NFS client uses a third
     consecutive interrupt (64h by default) if it is loaded
