Installing KYBDBUFR.OBJ is covered in README.1ST.
KYBDBUFR.OBJ has four switches that may be set at bootup time (if you don't
like the default values) by putting them on the line DEVICE=KYBDBUFR-
.OBJ in CONFIG.SYS. BE SURE to leave a blank space after "... .OBJ",
then put a "/", the first letter of the command, and the number to
which you wish to set the parameter. For example, the line:
DEVICE=KYBDBUFR.OBJ /b35/R3/V1
^ blank space
will set the keystroke buffer size to 35 (/b35, default is /b48),
place the buffer window on line 3 of the display (/r3, default is
/r1), and open the window as soon as KYBDBUFR.OBJ is loaded (/v1,
this is the default).
* /Bn, n = 15 to 255, sets the maximum number of keystrokes held in the
extended keystroke buffer
* /V0 closes the view-port to the keystroke buffer on bootup. The
view-port may be reopened by pressing KEYPAD 5, V after POWERKIT has
been loaded (unless the /N1 switch has been set, see below).
* /Rn, n = 1 to 25, tells KYBDBUFR.OBJ what line on the display you
want the WINDOW to appear.
* /N1 disables the view-port and replaces the code that operates the
view-port, with the buffer contents. This saves 95 bytes of memory.
UNLESS you have chosen to overwrite the code with the buffer (/N1), KYBDBUFR-
.OBJ uses only 101 bytes, plus twice whatever length the buffer is.
KYBDBUFR.OBJ will operate just fine whether POWERKIT is loaded or not.
NOTE: The luxury of POWERKIT's extended keystroke buffer may have to
be foregone in some cases. Unfortunately, some programmers think the
only buffer the BIOS (Basic Input Output System) supports is the small
buffer at 40h:1Eh. Their programs use this buffer exclusively, thus
ignoring the buffer whose dimensions the BIOS reads at 40h:80h. You
will know when you encounter such a program and POWERKIT's buffer is
set to more than 15 keystrokes, because your machine will hang and not
even KEYPAD 5, ESC (described in POWERKIT.DOC, page 7) will save you.
