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

if all registers preserved, restart DOS call
---DOS 2+---
CF clear
Return: all registers preserved
return via RETF with CF set or (MS-DOS 1,DR-DOS) RETF 2 with CF set
DOS will abort program with errorlevel 0
else (RETF/RETF 2 with CF clear or IRET with CF ignored)
interrupted DOS call is restarted
Notes: this interrupt is invoked whenever DOS detects a ^C or ^Break; it
should never be called directly
MS-DOS 1.25 also invokes INT 23 on a divide overflow (INT 00)
MS-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
MS-DOS 2.1+ ignores the returned CF if SP is the same on return as it
was when DOS called INT 23, so RETF 2 will not terminate the program
Novell DOS 7 always pops a word if CF is set on return, so one should
not return with RETF 2 and CF set or IRET with the stored flags' CF
set
any DOS call may safely be made within the INT 23 handler, although
the handler must check for a recursive invocation if it does
call DOS

INT 24 C - DOS 1+ - CRITICAL ERROR HANDLER
Notes: invoked when a critical (usually hardware) error is encountered by DOS
(see #1334); should never be called directly
when DOS terminates a program, it copies the previous value of the
INT 24 vector out of the PSP (see #0603) and into the interrupt
vector table

SS,SP,DS,ES,BX,CX,DX preserved
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 (AL set to 03h and the INT 24
call skipped)
Bitfields for critical error type and processing flags:
Bit(s) Description (Table 1335)

SS:SP = top of MS-DOS stack for I/O functions
Return: all registers preserved
Desc: This interrupt is 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 21h function except functions
00h through 0Ch.
Notes: 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 from
the INT 28h handler without destroying the DOS stacks.
calls to INT 21/AH=3Fh,40h from within an INT 28 handler 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

INT 2A CU - NETWORK - BEGIN DOS CRITICAL SECTION
AH = 80h
AL = critical section number (00h-0Fh) (see #1344)
Notes: normally hooked to avoid interrupting a critical section, rather than
called
the handler should ensure that none of the critical sections are
reentered, usually by suspending a task which attempts to reenter
an active critical section
the DOS kernel does not invoke critical sections 01h and 02h unless it
is patched. DOS 3.1+ contains a zero-terminated list of words
beginning at offset -11 from the Swappable Data Area
(see #0892 at INT 21/AX=5D06h); each word contains the offset within
the DOS data segment of a byte which must be changed from C3h (RET)
to 50h (POP AX) under DOS 3.x or from 00h to a nonzero value under
DOS 4+ to enable use of critical sections. For DOS 4+, all words in
this list point at the byte at offset 0D0Ch.
MS Windows patches the DOS kernel's calls to INT 2A/AH=80h-81h into
far calls to its own handler, and does not reflect the calls back
to INT 2A unless SYSTEM.INI contains ReflectDOSInt2A=1 or
ModifyDOSInt2A=0 in the [386Enh] section

INT 2A CU - NETWORK - END DOS CRITICAL SECTION
AH = 81h
AL = critical section number (00h-0Fh) (see #1344)
Notes: normally hooked rather than called
the handler should reawaken any tasks which were suspended due to an
attempt to enter the specified critical section
MS Windows patches the DOS kernel's calls to INT 2A/AH=80h-81h into
far calls to its own handler, and does not reflect the calls back
to INT 2A unless SYSTEM.INI contains ReflectDOSInt2A=1 or
ModifyDOSInt2A=0 in the [386Enh] section
SeeAlso: AH=80h,AH=82h,AX=8700h
--------D-2A82-------------------------------
INT 2A CU - NETWORK - END DOS CRITICAL SECTIONS 0 THROUGH 7
AH = 82h
Notes: called by the INT 21h function dispatcher for function 0 and functions
greater than 0Ch except 59h, and on process termination
the handler should reawaken any tasks which were suspended due to an
attempt to enter one of the critical sections 0 through 7

INT 2A CU - PRINT - BEGIN BACKGROUND PRINTING
AX = 8700h
CF clear
Return: CF clear if OK to print in background now
CF set if background printing not allowed at this time
Desc: used to inform interested programs that PRINT is about to start its
background processing, and allow those programs to postpone the
processing if necessary
Notes: when PRINT gains control and wants to begin printing, it calls this
function. If CF is clear on return, PRINT begins its background
processing, and calls AX=8701h when it is done. If CF is set on
return, PRINT will relinquish control immediately, and will not
call AX=8701h
PCVENUS (an early network shell by IBM and CMU) hooks this call to
prevent background printing while its own code is active

before the actual release.
--------m-2C---------------------------------
INT 2C R - Cloaking - CALL PROTECTED-MODE PASSALONG CHAIN
Notes: when this interrupt is invoked in V86 mode, RM386 will invoke the first
in a chain of protected-mode handlers, and will only pass execution
to the V86-mode INT 2C handler if none of the handlers in the
passalong chain handle the call instead. This is the method by which
the real-mode stub of a cloaked application communicates with the
protected-mode portion.
the cloaking host calls the passalong chain with EAX=58494E33h ('WIN3')
when MS Windows starts up and with EAX=334E4958h ('3NIW') when
Windows shuts down; between these two broadcasts, the additional
Windows-only Cloaking services are available
this function was first introduced with RM386 (RAM-MAN/386) v6.00, the

calls the passalong address. The handler should check whether the
upcall is of interest to it, and if not it should jump to the old
passalong address (retrieved with AX=0008h before the handler was
installed). The final handler should return with CF clear to cause
the interrupt to be reflected back to V86 mode if none of the
passalong handlers is triggered

which must be swapped out to pop up

CX = application's reason code if nonzero
FFh TSR popped up and was exited by user

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 #1358)
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 #1359)
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 #1363), 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
(AMISL091.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.

05h BYTE hotkey flags (see #1362)
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.
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

Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
