assistant: Hi..
D

This is typicly not possible, unless you happen to know where they all
originally point, before any TSR's get loaded (and redirect them). Normally
one would un-load each TSR in order... and as we all know, not all TSR's can
be unloaded.
Because once you begin to re-boot the DOS "memory map" no longer protects the
TSRs from being overwriteen by new programs getting loaded. In fact, the
debugger itself no longer is protected and gets overwritten "sooner or later"
too.
Once the TSR is overwritten, the next time that interrupt is called, "random"
data (that which overwrote the TSR) will be executed, since the interrupt
vector is still pointing there, and the net result is a crash.
You should be able to trace into int 19h a bit with a debugger, but not fully
execute it.
In order to fully debug this sort of program, you need something like a
"periscope" hardware board, which stores the debugger code in write protected
memory that is out of the 'normal' 640k area.... thus it is "un-trashable".
Periscope boards also have a way to get control backin many "hung"
tuations.
You could also try using TD286 or TD386 as your debugger - the 'extra'
protection mechanisms in these products *MAY* allow you to debug a bit
urther
into the code than just normal TD. (TD286 loads in extended memory, for
example, leaving your base memory free for the target program to load).

assistant: Hello Adam,
The only waste of time I can think of is for the processor reading the
opcode. Since the NOP-instruction exists out of 1 byte, it can be usefull for
lazy assembler-builders for JMP-opcodes followed by 1 or 2 bytes.

1 - Yes, it just wastes time. (I wish I were allowed to do that
ccasionally.)
Sometimes that wasting is (or rather: used to be) useful.
2 - Sometimes some padding is required in the code. E.g. 'primitive'
assemblers might initially code jumps as a three byte code. Ultimately
changing it to a two byte code and a NOP where possible.
3 - NOP is just "xchg ax, ax" iirc. getting rid of it entirely takes _extra_
stuff.

assistant: you've got, for instance a clock-tsr running, dos reboots and begins loading
stuff to arbitrary memory locations as it boots, all of a sudden something
overwrites the memory used by the TSR,  next time the timer ticks it's

while DOS is booting the memory allocation scheme is disabled/ignored.

assistant: Hi Adam;
There are two very useful places where one would use a NOP. One is to
simply provide a delay in the code. You can find some examples of
this in code using the IN and OUT instructions, especially in regards
to programming COM ports.
Another place is in patching code. When replacing a shorter snippet
of code over a larger section, the difference can be padded with a
few NOPs so the CPU will not stumble over it. Of course, anything
more than three NOPs should have a JMP.

user: You are replying to Anthony Tibbs about "OS/2 serial port".

Write your reply.

assistant: According to "OS/2 2.0 Control Program Programming Guide" page 14-1 to
14-5, to access the serial ports under OS/2 you have to use the API
          DosDevIOCtl
It has an example of writing contents to a disk file to the COM1
Serial Port, but it's in "C", as are all the other examples of how
to use DosDevIOCtl.
The Data Structure "LINECONTROL" is used to set the characteristics of
a COM port through the IOCtl interface. page 14-8
 I couldn't find anything on serial port programming for OS/2 in
assembler.

assistant: I wrote it like that for a reason. :)  Pascal generates all this
code I don't want, and last time I tried it wouldn't fit into the object.
Now it does..
  I'm sure.  (I think :)
u):)
  I think I'll uncomment those now..
  Gott'em backwards.. whoops..
  I think it does.  I could perhaps step through it with a debugger to see
if DX holds APort or some weird number.. but this is an ISR which may not
allow me to do that..
  I could.. but I'm lazy.
  You don't.. but it's an assembler proc, not an Interrupt; proc..
  It did. :) Thanks.

Can't you draw in modelspace (tilemode normal I think 1). Make different
layers view1, view2, viewetc. In those layers you put the entities that you
want to make visible in the different viewports. Than create a new drawing
with tilemode 0, now you're in paperspace, make the different viewports, go
to modelspace and set the layers per view frozen if they have to be
invisible. Than you don't have to change from MS to PS and back for zooming.

R10 is the last non-DOS extender version of ACAD.  There may not be a driver
