SETUP Jeff Prosise
Command PC Magazine Vol 5, No 12
Copyright 1986 Ziff-Davis Publishing Company
______________________________________________________

Purpose: Permits menu-oriented selection and immediate
transmission of printer control codes from
within a running application program.

Format: SETUP (loads command into memory)
(activates menu)
<[Shift] (selects [deselects] mode)
(activates selection(s) and
returns to application program)

Fx is a Function key (F1 through F10) that
sends the required control sequence to the
printer. Shift-Fx toggles the selected
printer mode off.

Remarks: After loading SETUP (normally via your
AUTOEXEC.BAT file), the printer mode
selection menu program is displayed by
pressing the Ctrl-Right Shift key
combination. This can be done from within
application programs that do not take over
the keyboard interrupts; the application is
simply suspended until you leave SETUP by
pressing the Esc key. (Application programs
such as XyWrite III that do take over the
keyboard interrupts can be used with
SETUP.COM if they themselves provide the
option of temporarily returning to DOS
control.)

Printer permitting, more than one mode can be
selected at once by pressing additional
function keys. The default printer choices
are for the Epson RX/FX series. Option 1
shows how to modify the program for other
printers.

Notes:

1. SETUP.COM is a memory-resident program
(approximately 3K in length), and so is
subject to conflicts with other memory-
resident software. Several users have
reported that it is incompatible with
Prokey, for example. Similarly, while
SETUP.COM is compatible with SideKick,
the combination of SuperKey and SideKick
has been reported to be incompatible.

Option 1: If you have access to an IBM or Microsoft
macro assembler, the easiest way to modify
SETUP for other printers (or to use LPT2: or
LPT3: instead of LPT1:) is to call up the
SETUP.ASM file (included with these
utilities) in any ASCII word processor. You
can then make your modifications and
reassemble the file.


Even if you do not have a macro assembler and
must therefore use DEBUG.COM to modify
SETUP.COM directly, print out and read the
SETUP.ASM file. It is heavily commented, and
will give you a good idea of how the
different menu strings and printer control
strings are organized. Note, however, that
the specific values shown in SETUP.ASM are in
decimal notation; values entered via DEBUG
must be in hexadecimal notation.

The following offset addresses, not those
originally published in PC Magazine, should
be used:

The menu color attributes (4F and 70) are at
offsets xxxx:013F and xxxx:0140.

To change the port number from LPT1: to LPT2:
(or LPT3:) change the default 00 at xxxx:0C7A
and at xxxx:0C84 to 01 (or 02).

The start of the menu text table (532 bytes,
beginning with C9) is at offset xxxx:0151.
The "P" in PRINTER SETUP MENU" is at
xxxx:0172.

The printer control strings themselves begin
at xxxx:09A1. Each function key (and each
shifted function key, with the exception of
F19 and F20) can be assigned a string up to
16 bytes long. Each string must include a
delimiter of FF (255 decimal) that marks the
end of the string. The beginning of the
string for each successive function key
starts at an address that is a multiple of 16
bytes above the base address (xxxx:09A1) of
the table. You must pad the strings with
zeros for any locations that are not used by
actual control codes, so that each string
begins on a 16-byte boundary.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. 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/
