- INTRODUCTION
-
- The DPD (Data Processing Directions) Alphanumeric Paging Software
- is designed to perform batch operation of message transmission from
- a PC to a message carrier via a Hayes compatible modem. It is
- written to transmit two fields per envelope: destination id and
- message. A message is currently limited to four twenty character
- lines. This accomplished by a menu driven software system that
- permits simple selection of needed functions.
-
- Functions are logically grouped to minimize screen switching and to
- present routinely used functions together in a common selection
- mechanism.
-
- GENERAL PROCEDURES
-
- Help
-
- Context sensitive help is available for many screens and functions.
- Pressing function key F1 will call up a help screen when one is
- available. To exit from a help screen, press the ESC key. While the
- help screens do not replace this manual, they are designed to
- complement this manual to enable you to use the system.
-
- Menus
-
- When you first start the program, you will see a menu offering you
- the basic system selections. In all menus you may select an item by
- using the arrow keys to highlight the desired item or you may type
- the first letter of the item. If there is more than one item
- starting with the same letter, repeated entry of that letter will
- cycle through the target items. Once properly positioned, press
- enter to complete the selection.
-
- Tables
-
- A tables is a selection mechanism that permits adding, deleting,
- and changing of data items. These functions are invoked by the
- INSERT, DELETE and ENTER keys. Some tables will have a "locator"
- field in the upper left hand corner of the screen. If the locator
- field is present, entering data will position the selection bar on
- the item containing data most closely matching the selection
- criteria that you are entering. Other tables may offer filter data
- next to the locator field. Entering data into this field will limit
- the display of table data to items exactly matching the filter
- item.
-
- Forms
-
- A form is a window that allows an individual record to be added,
- changed or deleted. Forms are usually opened based upon a table
- response. A form may be terminated and its effects reversed by
- pressing CTRL-ESC.
-
- Response Windows
-
- A response window is a window that opens in response to some menu
- selections. It will allow you to enter additional information to
- control your requested process.
-
- Navigation Keys.
-
- Key Function
- --- --------
- Enter Accept Data in field
- CTRL-Enter Accept Data in record
- CTRL-Home Erase current field
- CTRL-End Erase to end of field
- Esc Cancel change to field
- Insert Add new record
- Enter char insert mode
- Home Go to top of screen
- Go to beginning of field
- Pg Up Go to top of screen or scroll up one page
- Delete Delete record or character
- End Go to bottom of window
- Go to last char of field
- Pg Down Go to bottom of screen of scroll down one
- page
- Arrow Keys Move cursor.
-
- The addition of pressing the control key while pressing one of the
- above function keys alters the function of the key. CTRL-esc will
- cancel changes and exit from a form, exit from a menu and response
- box. If you can't seem to get out of a function, ESC. If that fails
- try CTRL-esc. In the case of movement keys, the movement spans the
- entire file. In a field, CTRL-home deletes the data in the field
- while CTRL-end deletes the data from the cursor on.
-
- INITIAL SETUP
-
- There is a specific order in which the initial setup tasks must be
- performed to insure proper system initialization.
-
- Setup Steps
- First:
- Set up the terminals (the message distributor that you will
- call) by selecting Configure System followed by System
- Preferences. Prefix the phone number with dt or dp (see help
- screens).
-
- The modem init string contains the control sequences necessary
- to cause the modem to function properly for dialing and task
- initialization. It should include the AT code followed by the
- codes to set no echo (E), quite mode off (Q0), numeric result
- codes (V0) and extended result codes on (x4).
-
- Leaving the modem init string blank will default to "AT E L3
- Q0 X4 V0 &C1 &D2", which is the string that seems to work the
- best. Your modem manual will offer you a complete description
- of control commands. Note: if only one terminal is entered it
- will be used automatically. If more than one is entered, you
- will be prompted for which one prior to sending messages.
-
- Second:
- Set up the pagers by selecting Pager Setup. If you wish to
- enter groups, they must be established (under the message and
- group maintenance menu item) before they can be referenced by
- the pager record.
-
- To send a message:
- Select Send a Message from the main menu. To write the message
- select Compose a message. The help screens should offer enough
- help to get you started. Just remember ESC gets you out of the
- help function. If you elect to send the message later, it will
- be queued to the message file as an open item ("snt flg" = O).
- Selecting Send Messages from the message composer screen will
- cause all messages (up to the count entered) to be sent to the
- run time selected terminal. If you have entered messages that
- should be directed to different terminals, it would be
- necessary to limit the send by using the count. However, the
- intent is that messages be sent now and directed to one
- terminal.
-
- Observations:
- Since messages, in a given transmission, are directed to one
- terminal; pagers on different terminals should NOT belong to
- the same group.
-
- Notes on operation:
- There is a two second guard time before and after the modem
- escape sequence (+++) yielding a four second delay prior to
- dialing.
-
- A low/hi tone indicates a timeout retransmission. Two high
- tones indicate a successful operation.
-
- When the program disconnects, it simply returns to the send
- menu. If multiple messages were sent, examining the message
- file (checking the "snt flg") will indicate the success of
- failure of the transmissions. If only one message is sent, the
- error indication will stay on the screen long enough to be
- obvious.
-
- Finally:
- This is a shareware product. You are free to try it without
- incurring any expense liability and you may copy the
- distribution file and pass it on to others (please). However,
- if you intend to use it you are obligated to pay for it. I am
- asking eighteen dollars
-
- Paying for it offers these advantages: 1) you will have a
- clear conscience - knowing that you have helped a struggling
- software developer survive another day, and 2) you will be
- informed on how to get rid of the annoying commercial beep -
- boop screen.
-
- Please note: I am more that willing (even anxious) to hear
- suggestions about product improvement or, if you are a
- registered user and have problems, I will help you resolve
- them by telephone or Compuserve Email.
-
- NEW:
- There is a "drone" version of the program available that
- permits the sending of messages but has NO configuration
- capabilities. Useful for satellite distribution.
