Int 2F Fn EE  - Web V4.02 - Web Module Installation Check                  [N]

   AH = EEh
   AL = module ID (see below)

       ES:DI -> far entry point for module-specific API calls (see below)
Program: WEB is an IPX-based peer-to-peer network by Webcorp.

See Also: AX=EE00h"WEB"

Values for module ID:
 10h   server module (SERVER.EXE)
 20h   client module (CLIENT.EXE)
 30h   mail module (MAIL.EXE)
 40h   spooler (PCSPOOL.EXE)
 50h   kernel module (KERNEL.EXE)
 60h   SAP module (KERNEL.EXE)
 70h   resident station manager (SM.EXE)

Call server module entry point with:
   BX = function
       0000h remove server module

       Return: AX = status (0000h if successful, else WEB error code)
       0001h create SYSINFO file

       Note:   the SYSINFO file is used by the station manager when
             displaying info for a particular station
       0002h get server object table

       Return: CX = number of server objects
           ES:DI -> server object table

       Note:   server objects include drives and devices that the
             server module controls
       0003h get server variables

       Note:   decrements DeviceOutput flag, telling the spooler that
             it may trap device output again
       0006h clear device capture

       Note:   increments DeviceOutput flag, telling the spooler that
             it should not trap device output (this is used
             internally by the spooler to prevent it from trapping
             its own output)
       0007h get client debug pointer

       Return: ES:DI -> client debug data structure (see below)
       0008h get root drive

       Return: AX = status (0000h successful, else WEB error code)
       0001h set mail poll

       Note:   schedules the WEB mail module
       0002h set mail notify

       Note:   sets the Notify flag, which determines whether the
             user will be notified when mail is received
       0003h clear mail notify

       Note:   clears the Notify flag, which determines whether the
             user will be notified when mail is received
       0004h check whether new mail has arrived

       Return: AL = new mail status
               00h no new mail since last call
               else new mail has arrived

       Note:   also clears the new-mail flag after retrieving it

       0000h remove PCSpool module

       Return: AX = status (0000h successful, else WEB error code)
       0001h set spooler poll

       Note:   schedules the WEB spooler
       0002h check spooler changed

       Return: AX = 0000h

       Note:   this call is a NOP in current versions of WEB

Call kernel entry point with:
   BX = function
       0000h remove kernel module

       Return: AX = status (0000h successful, else WEB error code)
       0001h set kernel S filter
       DL = new state (00h don't filter S, nonzero do filter)

           01h ignore ExtraBusy flag
           02h (WEB4WIN) check that current Windows VM is foregrnd VM
       ES:SI -> WEB AES Event Control Block (ECB) (see below)

       Notes:  the WEB Asynchronous Event Scheduler is similar to the
             one used by IPX; this call schedules a special ECB
             to be executed at a later time.  Unlike IPX ECBs,
             the timeout must be set explicitly by the caller
           this function also calls function 0004h
       0007h check busy
       AL = directive
           00h do not ignore WEB ExtraBusy flag
           01h ignore ExtraBusy flag
           02h (WEB4WIN) check that current Windows VM is foregrnd VM

       Return: AX = status (0000h not busy, else busy)
       0008h set keyboard intercept

       Note:   currently a NOP which returns immediately
       0009h get keyboard intercept

       Note:   currently a NOP which returns immediately
       000Ah get dialog flags

       Return: ES:DI -> kernel dialog flags (see below)
       000Bh get network path

       Return: ES:DI -> fully-qualified network path of file where
               the screen is stored on Dialog calls
       000Ch kernel alternate dialog
       CL = dialog box type
           00h password
           01h E-Note received notification
           02h Novell login
           03h general notification
       DL = number of rows to display
       ES:SI -> array of far pointers to rows to be displayed
       ES:DI -> Pascal-style input buffer

       Return: AX = status (0000h successful, else error code)

       Note:   this function is identical to function 0003h except
             that it does not notify WEB4WIN of the impending
             dialog request
       000Dh get machine/operating system type

       Return: AX = machine/operating system type
               01h IBM PC, MS-DOS
