- MDM7 update information 02/17/84
-
- Sigi Kluger, El Paso TX 02-17-84
-
- Being used to a great non-public modem program with a number of function
- keys, I decided to add ten function keys to MDM7. Great for things you
- do most, like DIR *.* $U0AD, or XMODEM S, or you could even save your
- name in a function key for logon.
-
-
- 1. HOW TO ACCESS (transmit) THE FUNCTION KEYS.
-
- You transmit the contents of a function key by typing first the INTERCEPT
-
- CHARACTER, then a digit 0..9. The INTERCEPT CHARACTER is an unique char-
- acter which tells MDM7 that a function key command follows. The INTERCEPT
- CHARACTER is set to ^ (circumflex). It could as easily be set to CTL-A
- or 'escape', for example. In the distribution version, the following
- keys are defined:
-
- ^A0 DIR <cr>
- ^A1 DIR *.* $U0AD <cr>
- ^A2 XMODEM S
- ^A3 XMODEM R
- ^A4 BYE <cr>
- ^A5 CBBS <cr>
-
- (Function keys 2 and 3 have no trailing CR).
-
-
- 2. HOW MUCH ROOM?
-
- A total of 256 bytes are reserved for the function key definition. Each
- definition takes up the number of bytes in the string, PLUS 2. Note that
- you must not enclose any control characters in the definitions (CR is
- allowed and is optional).
-
-
- 3. HOW TO CHANGE THE FUNCTION KEYS
-
- In order to not increase the size of MDM7 considerably, I have written
- the M7FNK utility. M7FNK.COM is virtually self-explanatory and it is
- covered by its own short DOC file. (M7FNK.COM v1.10 is current.)
-
-
- 4. WHAT WILL NOT WORK
-
- Do not attempt to use DDT to modify the function keys. Especially, do
- not force any control characters into the definitions. There can only
- be three non-printing characters in each definition, the start byte,
- an optional CR at the end, and the end byte.
-
-
- 5. DEFINITION FORMAT
-
- This is an example of the definition for function key 1:
-
- DB 1,'THIS IS A FUNCTION KEY',CR,0
- | | |
- | | |__stop character
- | |________________key definition plus CR
- |________________________________start character
-
- Each key definition string starts with the key number in binary. The
- function key processor searches for that number. Those numbers must be
- unique throughout the key definitions. EMPTY key definitions are en-
- coded thusly:
-
- DB 9,0 ;empty function key #9
-
