DOCUMENTATION for SD-QUIET.COM 11/11/86 S.H. Isaac
I usually call this modified directory program D.COM, but for now
I called it this name to indicate that it quiets the keyboard chirp
of the Kaypro 2-84. It also changes the cursor from a blinking block to a
blinking underline. How it will work on other computers remains to be
seen. If it doesn't do what you want, check your computer's manual & find
out what bytes should be sent to the keyboard and/or the video controller
(it has some other name, but I forget what it is).
The byte 8 is sent to the keyboard and quiets it. Then another byte
is sent to the video to select what aspect of it to deal with; the byte
0A selects cursor nature( height, blink rate, etc). Then the byte 6F is
sent to the video to tell it to make the cursor a fast blinking under-
line.
The sequence of bytes is:
3E08
D305 Quiets keyboard.
3E0A
D31C Selects cursor nature as video aspect to work on.
3E6F
D31D Sends byte to change cursor.
[I put the same sequence in WordStar.COM, at address 300h (in the user-
patching area), and followed it immediately with this one:
0EOE 1E01 CD0500
This logs on to drive B before jumping (via C3FC2C) back to where
WordStar was going in the first place]
I got the cursor changing from an article in PROFiles magazine, sorry
I forgot which one, but it was sometime between December 1984 and now
(December 1986). The keyboard quieting was based on something from the
Kaypro manual, and maybe on something I read elsewhere.
Probably the directory program I patched was SD.COM, which mau have
come from a bulletin board. It was chosen because it has a nice big
empty area, which is around address 860h when viewed with EDFILE.COM
or DDT.COM.
SD.COM starts with a JMP to address 113h. What we do is change that
to JMP to our quieting-and-cursor-changing statements at address 0860,
then to JMP to 113 where the program can go on about its business.
Subsequently I used DU.COM to make this modified directory program
auto-execute on a cold start or reset. Put the command, such as
D *.* $D at byte 08h on sector 2, track 0 ; put the length of the
command, in this example 8 (bytes long), at byte 07h, just preceding
the command. Clear out any junk (such as DRI's copyright notice)
after the command you want autoexecuted, if it interferes with proper
operation of the command. DON'T blank out anything if you are not
sure of what you're doing.
Feel free to change this documentation or the program & pass it
around. If you can, let me know what you've come up with.
Here's how to modify SD.COM, a (public domain?) directory program,
using EDFILE.COM. The latter can be found on SIG/M volume 228, and
maybe on bulletin boards also. My comments are in curly braces,
{like this}.
