INT 21 - European MSDOS 4.0 - "AEXEC" - EXECUTE PROGRAM IN BACKGROUND
AH = 80h
CX = mode
0000h place child in zombie mode on exit to preserve exit code
0001h discard child process and exit code on termination
DS:DX -> ASCIZ full program name
ES:BX -> parameter block (as for AX=4B00h)
Return: CF clear if successful
AX = Command Subgroup ID (CSID)
CF set on error
AX = error code (see AH=59h)
Desc: asynchronously execute a program, creating a new process for it
Notes: this function is called by the DETACH command
there is a system-wide limit of 32 processes
the CSID is used to identify all processes that have been spawned by
a given process, whether directly or indirectly
programs to be run in the background must use the new executable format
(see AH=4Bh)
background processes may only perform asynchronous (background) EXECs,
either this function or AX=4B04h
background processes may execute INT 11, INT 12, INT 21, INT 2A, and
INT 2F at any time; they may execute INT 10 and INT 16 only while
they have opened a popup screen via INT 2F/AX=1401h; no other
interrupts may be executed from the background
background processes may not use drive B: or overlay their code
segments

CX = Process ID of head of command subtree
Return: CF clear if successful
CF set on error
AX = error code (no such process)
Desc: temporarily suspend a process or a process and all of its children
Note: if BX=0001h, this call will not return until the process is actually
frozen, which may not be until after it unblocks from an I/O
operation
SeeAlso: AH=82h,AH=89h,AX=8E00h,INT 15/AX=101Dh
----------2182-------------------------------
INT 21 - European MSDOS 4.0 - "RESUME" - RESTART A PROCESS

process
Note: if the partition size is set to 0000h, no partition management is done
and all memory allocation is compatible with DOS 3.2.
the partition size can be changed regardless of what use is being made
of the changed memory; subsequent allocations will follow the
partition rules (foreground processes may allocate only foreground
memory; background processes allocate background memory first, then
foreground memory)

CF set on error
AX = error code (06h,08h) (see AH=59h)
Desc: adjust the size of the per-process open file table, thus raising or
lowering the limit on the number of files the caller can open
simultaneously
Notes: any currently-open files are copied to the new table
if the table is increased beyond the default 20 handles, only the
first 20 will be inherited by child processes

scheduler clock, and may be extended further if other processes are
running
this call may be interrupted by signals (see AH=8Dh)
reportedly called by Microsoft C 4.0 startup code
background processes have higher priority than the foreground process,
and should thus periodically yield the CPU

INT 22 - DOS 1+ - PROGRAM TERMINATION ADDRESS
Desc: this vector specifies the address of the routine which is to be given
control after a program is terminated; it should never be called
directly, since it does not point at an interrupt handler
Notes: this vector is restored from the DWORD at offset 0Ah in the PSP during
termination, and then a FAR JMP is performed to the address in INT 22
normally points at the instruction immediately following INT 21/AH=4Bh
call which loaded the current program

Return: all registers preserved
return via RETF or RETF 2 with CF set
DOS will abort program with errorlevel 0
else (RETF/RETF 2 with CF clear or IRET)
interrupted DOS call is restarted
Notes: this interrupt is invoked whenever DOS detects a ^C or ^Break; it
should never be called directly
MSDOS 1.25 also invokes INT 23 on a divide overflow (INT 00)
DOS remembers the stack pointer before calling INT 23, and if it is
not the same on return, pops and discards the top word; this is what
permits a return with RETF as well as IRET or RETF 2
any DOS call may safely be made within the INT 23 handler, although
the handler must to check for a recursive invocation if it does
call DOS

Notes: the only DOS calls the handler may make are INT 21/AH=01h-0Ch,30h,59h
if the handler returns to the application by popping the stack, DOS
will be in an unstable state until the first call with AH > 0Ch
for DOS 3.1+, IGNORE (AL=00h) is turned into FAIL (AL=03h) on network
critical errors
if IGNORE specified but not allowed, it is turned into FAIL
if RETRY specified but not allowed, it is turned into FAIL
if FAIL specified but not allowed, it is turned into ABORT
(DOS 3+) if a critical error occurs inside the critical error handler,
the DOS call is automatically failed

INT 28 - DOS 2+ - DOS IDLE INTERRUPT
Invoked each time one of the DOS character input functions loops while
waiting for input. Since a DOS call is in progress even though DOS is
actually idle during such input waits, hooking this function is necessary
to allow a TSR to perform DOS calls while the foreground program is
waiting for user input. The INT 28h handler may invoke any INT 21 function
except functions 00h through 0Ch. Under DOS 2.x, the critical error flag
(the byte immediately after the InDOS flag) must be set in order to call
DOS functions 50h/51h without destroying the DOS stacks.
Notes: calls to INT 21/AH=3Fh,40h may not use a handle which refers to CON
at the time of the call, the InDOS flag (see INT 21/AH=34h) is normally
set to 01h; if larger, DOS is truly busy and should not be reentered
the default handler is an IRET instruction
supported in OS/2 compatibility box

COMMAND.COM v3.2 and v3.3 compare the INT 29 vector against the INT 20
vector and assume that ANSI.SYS is installed if the segment is larger
the default handler under DOS 2.x and 3.x simply calls INT 10/AH=0Eh

contains the offset within the IBMDOS segment of a byte which must
be changed from C3h to 50h to enable use of critical sections.

INT 2D - ALTERNATE MULTIPLEX INTERRUPT SPECIFICATION (AMIS) [v3.5]
AH = multiplex number
AL = function
00h installation check
Return: AL = 00h if free
AL = FFh if multiplex number in use
CX = binary version number (CH = major, CL = minor)
DX:DI -> signature string (see below) identifying
the program using the multiplex number
01h get entry point
Return: AL = 00h if all API calls via INT 2D
AL = FFh if entry point supported
DX:BX -> entry point for bypassing interrupt chain
02h uninstall
DX:BX = return address for successful uninstall (may be
ignored by TSR)
Return: AL = status
00h not implemented
01h unsuccessful
02h can not uninstall yet, will do so when able
03h safe to remove, but no resident uninstaller
(TSR still enabled)
BX = segment of memory block with resident code
04h safe to remove, but no resident uninstaller
(TSR now disabled)
BX = segment of memory block with resident code
05h not safe to remove now, try again later
FFh successful
return at DX:BX with AX destroyed if successful and
TSR honors specific return address
03h request pop-up
Return: AL = status
00h not implemented or TSR is not a pop-up
01h can not pop up at this time, try again later
02h can not pop up yet, will do so when able
03h already popped up
04h unable to pop up, user intervention required
BX = standard reason code
0000h unknown failure
0001h interrupt chain passes through memory
which must be swapped out to pop up
0002h swap-in failed
CX = application's reason code if nonzero
FFh TSR popped up and was exited by user
BX = return value
0000h no return value
0001h TSR unloaded
0002h-00FFh reserved
0100h-FFFFh application-dependent
04h determine chained interrupts
BL = interrupt number (except 2Dh)
Return: AL = status
00h not implemented
01h (obsolete) unable to determine
02h (obsolete) interrupt hooked
03h (obsolete) interrupt hooked, address returned
DX:BX -> TSR's interrupt BL handler
04h list of hooked interrupts returned
DX:BX -> interrupt hook list (see below)
FFh interrupt not hooked
Notes: since INT 2D is known to be hooked, the resident code
need not test for BL=2Dh (to minimize its size), and
the return value is therefore undefined in that case.
BL is ignored if the TSR returns AL=04h; in that case,
the caller needs to scan the return list rather than
making additional calls to this function. If the
return is not 00h or 04h, then the caller must cycle
through the remaining interrupt numbers it wishes to
check.
return values 01h thru 03h are disparaged and will be
removed from the next version of this specification;
they are included for compatibility with version 3.3,
though they were probably never used in any
implementation
05h get hotkeys
Return: AL = status
00h not implemented
FFh supported
DX:BX -> hotkey list (see below)
06h-0Fh reserved for future enhancements
Return: AL = 00h (not implemented)
other application-dependent
Notes: programs should not use fixed multiplex numbers; rather, a program
should scan all multiplex numbers from 00h to FFh, remembering the
first unused multiplex in case the program is not yet installed.
For multiplex numbers which are in use, the program should compare
the first 16 bytes of the signature string to determine whether it
is already installed on that multiplex number. If not previously
installed, it should use the first free multiplex number.
functions other than 00h are not valid unless a program is installed
on the selected multiplex number
to be considered fully compliant with version 3.5 of the specification,
programs must implement at least functions 00h, 02h (no resident
uninstall code required), and 04h (return value 04h). TSRs that
provide hotkeys with which the user can activate them must also
implement function 05h. The absolute minimum fully-compliant
implementation has an overhead of 64 bytes (80 bytes with function
05h) plus 22 bytes per hooked interrupt (for the interrupt sharing
protocol header and hook list entry).
the signature string and description may be used by memory mappers
to display the installed programs
users of this proposal should adhere to the IBM interrupt sharing
protocol (see below), which will permit removal of TSRs in
arbitrary order and interrupt handler reordering. All TSRs
following this proposal should be removable, though they need not
keep the code for removing themselves resident; it is acceptable
for a separate program to perform the removal.
A sample implementation including example TSRs and utility programs
may be found in a separate package distributed as AMISLnnn.ZIP
(AMISL090.ZIP as of this writing).
Please let me know if you choose to follow this proposal. The
signature and a list of the private API calls you use would be
appreciated, as well.
SeeAlso: INT 2F
Format of signature string:
Offset Size Description
00h 8 BYTEs blank-padded manufacturer's name (possibly abbreviated)
08h 8 BYTEs blank-padded product name
10h 64 BYTEs ASCIZ product description (optional, may be a single 00h)
Note: it is not necessary to reserve a full 64 bytes for the description,
just enough to store the actual ASCIZ string
Format of interrupt hook list [array]:
Offset Size Description
00h BYTE interrupt number (last entry in array is 2Dh)
01h WORD offset within hook list's segment of the interrupt handler
this will point at the initial short jump of the interrupt
sharing protocol header (see below)
Format of hotkey list:
Offset Size Description
00h BYTE type of hotkey checking
bit 0: checks before chaining INT 09
bit 1: checks after chaining INT 09
bit 2: checks before chaining INT 15/AH=4Fh
bit 3: checks after chaining INT 15/AH=4Fh
bit 4: checks on INT 16/AH=00h,01h,02h
bit 5: checks on INT 16/AH=10h,11h,12h
bits 6,7: reserved (0)
01h BYTE number of hotkeys (may be zero if TSR can disable hotkeys)
02h 6N BYTEs array of hotkey definitions
(one per hotkey, first should be primary hotkey)
Offset Size Description
00h BYTE hotkey scan code (00h/80h if shift states only)
hotkey triggers on release if bit 7 set
01h WORD required shift states (see below)
03h WORD disallowed shift states (see below)
05h BYTE flags
bit 0: hotkey chained before processing
bit 1: hotkey chained after processing
bit 2: others should pass through this hotkey
so that it can be monitored
bit 3: hotkey will not activate if other keys
pressed/released before hotkey press is
completed
bit 4: this key is remapped into some other key
bit 5-7: reserved (0)
Notes: except for bit 7, the shift states correspond exactly to the return
values from INT 16/AH=12h. A set bit in the required states word
indicates that the corresponding shift state must be active when the
hotkey's scan code is received for the hotkey to be recognized; a
clear bit means that the corresponding state may be ignored. A set
bit in the disallowed shift states word indicates that the
corresponding shift state must be inactive.
if bit 2 is set, either control key may be pressed for the hotkey; if
bits 8 and 10 are both set, then both control keys must be pressed.
Similarly for bits 3 and 9/11, as well as 7 and 0/1.
for the disallowed-states word, if one of the "either" bits is set,
then both the corresponding left bit and right bit must be set
examples:
Ctrl-Alt-Del monitoring: 53h 000Ch 0003h 06h
Alt-key tap (DESQview): B8h 0000h 0007h 08h
Shf-Shf-N (NOTE.COM): 31h 0003h 000Ch 00h
Bitmask of shift states:
bit 0: right shift pressed
bit 1: left shift pressed
bit 2: either control key pressed
bit 3: either Alt key pressed
bit 4: ScrollLock active
bit 5: NumLock active
bit 6: CapsLock active
bit 7: either shift key pressed
bit 8: left control key pressed
bit 9: left Alt key pressed
bit 10: right control key pressed
bit 11: right Alt key pressed
bit 12: ScrollLock pressed
bit 13: NumLock pressed
bit 14: CapsLock pressed
bit 15: SysRq key pressed
Format of interrupt sharing protocol interrupt handler entry point:
Offset Size Description
00h 2 BYTEs short jump to actual start of interrupt handler, immediately
following this data block (EBh 10h)
02h DWORD address of next handler in chain
06h WORD signature 424Bh
08h BYTE EOI flag
00h software interrupt or secondary hardware interrupt handler
80h primary hardware interrupt handler (will issue EOI)
09h 2 BYTEs short jump to hardware reset routine

INT 2E - DOS 2+ - PASS COMMAND TO COMMAND INTERPRETER FOR EXECUTION
DS:SI -> commandline to execute (see below)
Return: all registers except CS:IP destroyed
AX = status (4DOS v4.0)
0000h successful
FFFFh error before processing command (not enough memory, etc)
other error number returned by command
Notes: this call allows execution of arbitrary commands (including COMMAND.COM
internal commands) without loading another copy of COMMAND.COM
if COMMAND.COM is the user's command interpreter, the primary copy
executes the command; this allows the master environment to be
modified by issuing a "SET" command, but changes in the master
environment will not become effective until all programs descended
from the primary COMMAND.COM terminate
since COMMAND.COM processes the string as if typed from the keyboard,
the transient portion needs to be present, and the calling program
must ensure that sufficient memory to load the transient portion can
be allocated by DOS if necessary
results are unpredictable if invoked by a program run from a batch file
because this call is not reentrant and COMMAND.COM uses the same
internal variables when processing a batch file
hooked but ignored by 4DOS v3.0 COMMAND.COM replacement unless SHELL2E
has been loaded
