Int 2F/AX=B800h

NETWORK - INSTALLATION CHECK

AX = B800h

Return:
AL = status
00h     not installed
nonzero installed
BX = installed component flags (test in this order!)
bit 6   server
bit 2   messenger
bit 7   receiver
bit 3   redirector
bit 1   LANPUP (LANtastic 4.0)

Notes: This function is supported by PC LAN Program, LAN Manager, LANtastic, NetWare Lite, SilverNET, 10NET, etc.. LANtastic and NetWare Lite use only BL for the return value, preserving BH; LAN Manager and DOS LAN Requester return BH=00h. This permits differentiation between those two groups by setting BH to a nonzero value before the call and checking its value on return.
