CARDFILE Jeff Prosise
Command 1987/No. 17 (Utilities)
_______________________________________________________
Purpose: Combines a database of names, addresses,
phone numbers, and memo-IDs with a Hayes-
compatible autodialer.
Format: CARDFILE [d:][filespec]
Remarks: CARDFILE is normally loaded with a specific
database (filespec) by being listed as a line
in your AUTOEXEC.BAT file. You can swith to
another database by repeating the command
with a different filespec at the DOS prompt.
The Alt-Right Shift key combination pops up
the CARDFILE window, and Esc returns you to
your application. Within the window, the
Function keys are assigned thus:
F1 - Begin/save a new or edited card
F2 - Edit the card currently displayed
F3 - Delete the card currently displayed
F4 - Search all cards for a text string
F5 - Save datafile to disk
F6 - Dial the phone number currently
displayed
All card data entry and editing is done in
overstrike mode. The backspace key deletes
the previous character and the four cursor
keys can position the cursor anywhere in the
record area. Enter moves the cursor to the
start of the next line. You can page through
all of the cards with the PgUp, PgDn, and
Enter keys. The HOME and END keys let you
jump quickly to the first or last card,
respectively.
To search the database, press F4 and entera
text string. Pressing Enter resumes the
search (which is not case-sensitive) after a
match; Esc cancels the search. An alternate
way to find a name quickly is to press Alt
and a letter key. To find "Smith," for
example, hit Alt-S, then use PgDn or Enter to
skip past "Sagamore" and "Siddhartha."
When used with Hayes-compatible modems, F6
dials the number currently displayed. At the
prompt, pick up the phone and press the
Spacebar to break the modem connection. The
CARDFILE autodialer ignores all non-numeric
characters except the comma, which inserts
the pause sometimes needed to access an
outside line.
Because CARDFILE is a memory-resident
program, it must assume rather than change
the modem parameters. By default,CARDFILE is
initially configured for a 1200-baud modem
connected to the COM1. Using DEBUG you can
change the value at :0182 from 0 to 1 to
change from COM1 to COM2, to 2 for COM3, etc.
Similarly, to change to a different baud
(bps) rate, change the value at :0184h from
the default 83h, as follows:
300 baud 43h
1200 baud 83h
2400 baud A3h
4800 baud C3h
9600 baud E3h
The "ATDT" (dial) and "ATH0" (hangup) strings
are at addresses :0185h and :018Ah,
respectively. While they can be changed
(especially substituting a "P", ASCII 80 for
the "T" in the dialing command, note that
each sequence must be 4 bytes long. The dial
string must be delimited by a zero byte, and
the hangup string must end with 0Dh and 00.
To save memory, the card capacity may be
lowered from the default 255 (FFh) at :0169.
Each record takes 192 bytes. And if the Alt-
Right Shift "hot key" conflicts with other
software, change the default value 09 at
address :036A to a combination of the
following:
Right-Shift 1
Left-Shift 2
Ctrl 4
Alt 8
Note: While CARDFILE will operate under DOS
2.x, its critical error handler is only fully
effective with DOS 3.x.
