- PLEASE READ THIS FILE FIRST BEFORE YOU PROCEED
-
-
- We have assembled all current overlays and other information
- on MDM727 on Volumes 168, 169 and 170 together with a completely separate
- communication program, COMM725. Both of these programs are excellent
- and one or both should suit your requirements.
-
- For both space and ease of use reasons, we have removed these
- files from the .LBR format. We have had to leave them squeezed, but
- have included the current wildcard version of unsqueeze.
-
- In most cases to assemble MDM727 you unsqueeze the overlay file
- for your computer and edit in any changes called for by the file. All of
- these changes are clearly explained in the overlay files. Also in the
- overlay file are instructions on how to assemble the file. COMM7 is
- assembles with LASM.COM, which is provided.
-
- NOTE: Modem 727 grew in size from the earlier versions to 73
- sectors. Some of the overlays call for a smaller "SAVE." Please read the
- note at the end of this file.
-
- As part of this memorandum we have included the file note on the
- additional size and the update note explaining the function key addition.
- Please read them before you proceed.

- TOPIC: MDM727.ASM MODEM PROGRAM
-
- FROM : IRV HOFF W6FFC
-
- DATE : 03 MAR 84
-
-
- NOTE: This program when assembled is 73 sectors
- long. Use this figure when merging the
- appropriate overlay file for your computer
- via DDT, etc. (Most of the overlays were
- written when MDM7xx.COM was only 66 sectors
- and the example included in each says to
- store 66 sectors.) For MDM727 use:
-
- B>SAVE 73 MDM727.COM
-
- NOTE: Use M7FNK.COM to easily and quickly change
- any of the 10 function key assignments. You
- can read the M7FNK.DOC file for additional
- information. (by Sigi Kluger.)
-
- NOTE: M7LIB.COM is a rapid and surprisingly easy
- way to quickly change any entries in the
- phone number library. See M7LIB.DOC if
- instructions are needed. M7NM-6.ASM is
- necessary for setting or altering numbers
- for 'SPRINT', 'MCI', etc. It would also
- be better if making a lot of changes such
- as adding or deleting '1-' required for
- long distance dialing in some areas.
-
- NOTE: If using the phone number overlay to change
- the phone library numbers, be sure to use:
-
- M7NM-6.ASM
-
- (Previous versions of M7NM will not work with
- this new version, as the phone number library
- now contains 36 numbers (A-Z as usual plus 0-9)
- rather than the 26 in versions prior to MDM722.)
-
- Most users will not need the lengthy (162k) source code at all.
- Just get MDM727.COM and then check one of the associated over-
- lay programs to obtain the overlay for your particular computer.
- Merge that with MDM727.COM according to the instructions near
- the start of the overlay file, using DDT.COM, etc. (See above
- note relative to saving 73 sectors. STAT.COM would then show
- 146 records for 20k.)
-
- The following bytes can be changed easily with DDT, then SAVE 73
-
- 0DFEH - HEXSHOW 00 = do not show hex record count
- FF = show both hex and decimal count
- 0DFFH - SAVSIZ 20 = 4k file transfer buffer size
- (see table below for other options)
- 0E00H - NUMBLIB (start of telephone number library)
-
- To change the file transfer buffer size via DDT, change byte 0DFFH:
-
- 10 (hex) = 16 records = 2k
- 20 (hex) = 32 records = 4k
- 40 (hex) = 64 records = 8K
- 60 (hex) = 96 records = 12k
- 80 (hex) = 128 records = 16k

- RECENT CHANGES:
- --------------
-
- (READ THE UPDATE HISTORY IN MDM727.ASM FOR MORE DETAILED INFORMATION)
-
- MDM727 - function key character shown in menu. Typing that character
- on command line shows all function key definitions, providing
- more versatility and ease in using the function keys. Fixed
- the dialing routine so phone library lines from (0-9) can now
- redial and continuously redial properly.
-
- MDM726 - 'T' no longer needed to return to terminal mode after a file
- transfer, i.e., 'RT' or 'ST' no longer used, just 'R' or 'S'.
- Exit routine changed to enable returning to CP/M even though
- incoming characters are still arriving.
-
- MDM725 - function key character can be used now even if it is a control
- character and local character required before control character.
- ACKNAK permanently set to robust mode. Option permits a retry
- for TYM-SHAR mainframes not using XMODEM, if set 'NO'.
-
- MDM724 - added 10 function keys for auto-typing preselected messages
-
- MDM723 - alphabetizes the phone library vertically for:
- 'CAL' - used with auto-dial modems including PMMI
- 'NUM' - used with manually-dialed modems
-
- MDM722 - phone number library now has 36 entries rather than 26 (has
- A-Z as usual plus 0-9). Better supports single-digit result
- codes for the Anchor Mark XII modem as well as Hayes and USR.
-
- MDM721 - makes it easier to abort an auto-dial call with CTL-X.
-
- MDM720 - changed from BIOS to BDOS call to run the printer.
-
- MDM719 - modest changes, PMMI pulse dialing set faster.
-
- MDM718 - now supports the Anchor Mark XII modem. Buffer size for ASCII
- capture set for 16k. Buffer size for file transfers adjustable
- from 1 sector to 16k. (Allows for slow floppy disk systems so
- XMODEM does not show a timeout error.)
-
- MDM717 - Log-on now works properly on main frames that echo characters
- with parity set.
-
- MDM716 - Robust addition to minimize problems due to intermittent noise.
- Gives added protection against timeouts on mainframes. Batch
- mode transfer improved.

- 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
-
-
