- MODM700.INF
- Nov. 4, 1984
-
- The recently-added auto-linking gives the user an opportunity to
- contact any of a group of numbers and greatly simplifies calling just
- one number. It also offers an unique choice of options as illustrated
- below. The same program is now equally effective on either mainframes
- with logon messages or RCPM systems that expect some user-typed
- characters to start the operation.
-
- ----------------------------------
- AUTO-LINKING PHONE NUMBERS
-
- If the number you want to dial is busy, you would like to have it
- automatically redialed until it answers. However, you might like to
- call any of a group of numbers and be happy to take whichever one first
- becomes available. Auto-linking allows a group of numbers to be listed
- and they are then continuously dialed one after the other, until one is
- available.
-
- MODM700 permits from 1-32 numbers to be linked together in any way.
- There are two options:
-
- B>>COMMAND: CAL A,D,R,3,Z 1)
- B>>COMMAND: CAL F, 2)
-
- B>>COMMAND: CAL A/D/R/3/Z 3)
- B>>COMMAND: CAL F/ 4)
-
- B>>COMMAND: CAL A,D,A,R,A,3,A,Z 5)
-
- B>>COMMAND: CAL F 6)
-
-
- 1) using a comma (,) will beep continuously when connected to
- the first available number - touching any key stops the beep
- and goes to terminal mode.
-
- 2) just the one number is linked to itself and redials until
- connected. Beeps continuously until stopped with any key.
-
- 3) using a slash (/) will beep only once when connected and then
- automatically go directly to terminal mode - this is useful
- where some mainframes such as IBM and UNIX send a logon note
- assuming you are already able to copy as soon as connected.
-
- 4) just the one number is linked to itself and redials until
- connected. Beeps only once and goes to terminal mode.
-
- 5) illustrates how one number can be given top priority.
-
- 6) system used previously - if connected on first try, beeps one
- time and jumps directly to terminal mode. If no connection,
- asks the operator if he wants to try again or try continuous-
- ly until a connected is made - at which time it beeps until a
- key is depressed.
-
- ----------------------------------
- ADDITIONAL CHANGES TO MODM700
-
- a) If the disk filled while in the terminal mode and copying to
- disk, the FCB file name was being closed instead of the FCB3
- file name. That has been fixed. The original system was
- developed for normal file transfer and this oversight was
- never noticed.
-
- b) The command line backspace has been fixed - that dates back to
- MODEM7 days. If a CTL-character was accidently typed, and you
- backspaced, the cursor would move, frequently moving "too far
- left". Fixed now for normal operation.
-
- c) Several changes suggested by Ron Fowler and Bob Plouffe for
- batch mode transfer when using BYE and checksum operation.
-
- d) Problem with the alternate long distance dialing (Sprint, MCI,
- etc.) fixed. Added a short delay between the digits in a phone
- number when sent to the modem to allow the alternate dialing
- systems to work properly. (Previously a problem on many modems.)
- (PMMI modems not affected.)
-
- e) Ringback fixed to work properly whether hand entered numbers or
- from the main table via a single character. Of interest mostly
- to PMMI users, although some intelligent modems can detect rings
- when dialing and can call ringback numbers. (Are there are such
- things still in existence?)
-
- f) Those using autodial will no longer see any +++ ATH ATD etc.
- Instead you will see messages (Busy for Anchor), No Connect, On
- Line, etc. when connected. An error prints Abort. Each attempt
- now has its own line - this seemed more appropriate when using
- linking, plus looks better with the messages added.
-
- g) Several other small changes in the menu. For example, when
- displaying the function key intercept character, etc. (An ESC
- showed as ^[ previously.)
-
- NOTE: ALL NORMAL OVERLAYS WILL WORK ON
- MODM700. SPECIAL OVERLAYS THAT ARE
- VERSION DEPENDENT THAT WERE USED
- WITH MDM730 WILL WORK ON MODM700.
- THOSE SPECIAL ONES (SUCH AS FOR
- THE MICROMODEM, NOVATION, OSBORNE
- COMM-PAC), ETC. WILL NOT OFFER AUTO-
- LINKING UNLESS FURTHER MODIFIED.
-
- ----------------------------------
- IF ',' OR '/' ARE NOT SUITABLE:
-
- Comma and the slash are used for delimiters on auto-linking. If
- you to need to use the comma to get out of the local exchange, you can
- change either of the delimiters to something different:
-
- 04FD 2F ASCII / (slash)
- 0502 2C ASCII , (comma)
-
- ----------------------------------
- PATCH TO GO TO TERMINAL MODE QUICKER:
-
- If going directly to terminal mode and it still takes too long to
- adequately receive signon messages from IBM or UNIX mainframes, try one
- of the following two changes:
-
- MOD1 067F 06 02 CD to C3 9B 06
- 069F C2 7E 19 to C2 18 16
- 06A6 CA 7E 19 to CA 18 16
- or
-
- MOD2 0966 CD 83 01 to C3 18 16
-
- ----------------------------------
- TO EXIT 'CAL' MORE QUICKLY
-
- If it seems to take too long to exit the table of telephone numbers
- with a simple 'return' check the following byte:
-
- 04F4 91 to 9D
-
- ----------------------------------
- PATCH TO SLOW THE FUNCTION KEYS:
-
- Currently the function keys send a character and wait for an echo.
- Since some people use 1-2 of the keys for secret passwords for mainframe
- use (where the characters are not echoed back), there has to be a com-
- promise between the length of time you are willing to wait for the echo
- character to be returned. Normally it is returned very shortly after it
- is sent but on some systems it may take longer. It is currently set to
- wait a maximum of 200 milliseconds. (A normal character takes 33 milli-
- seconds at 300 baud). If this is too slow and takes too long to submit
- your secret password try this change:
-
- 1E6D CD 8C 01 to 7C 7C 7C
-
- If either this or the original setting is too fast, you will drop
- some characters from showing on the CRT under normal use. If the origi-
- nal setting is still too fast, and you do not use secret passwords which
- are not echoed, you can use this change:
-
- 1E6D CD 8C 01 to 47 06 01
- 1E70 DC 8C 01 to CD D4 28
-
- This will wait up to one full second for the character to be echoed
- back and should be quite satisfactory on even the slowest systems. (We
- used this originally, before some people started using the function keys
- for secret passwords, such as signing on to Compuserve, etc.)
-
- ----------------------------------
- PATCH TO NOT SHOW "SPRINT" NUMBERS:
-
- If for some reason you do not wish to see the alternate long dis-
- tance dialing numbers, etc., make this change:
-
- 07FB CD 9D 2B to 00 00 00
- 0818 CD 9D 2B to 00 00 00
-
- ----------------------------------
- PATCH TO "UNDO-J"
-
- In past years when copying a file, you needed a lot of characters
- on the command line when using MODEM7. That program was explicity for
- use with the PMMI S-100 modem. Times change and so have modems. As
- recently as a year or so ago, even without a PMMI modem you had to say:
-
- B>>COMMAND: RCT
-
- to receive a file with CRC and then jump to terminal mode when finished.
- If working modem to modem, only one person could do this, the other had
- to be in echo mode and he had to wait until the file was finished and at
- that time say:
-
- B>>COMMAND: E
-
- to go to echo so the two of you could talk via the keyboard and discuss
- the name of the next file to be sent, etc. What a nuisance. That has
- been fixed so now the person receiving the file says:
-
- B>>COMMAND: R
-
- and this assumes CRC protocol and will automatically return to terminal
- mode upon file completion. This allows him to select "E" or "T" or "L"
- originally. This has never been possible prior to MDM730. It is one
- of the finest features recently added, as no "RT" or "ST" is needed.
-
- This gives several advantages. Allows automatic and simple use of
- modem-to-modem between two systems. As soon as you see the transfer is
- done, either party can start typing without saying "are you copying this
- now?" (Standard query prior to MDM730.) It also gives a standard for-
- mat since when using XMODEM on RCPMs you only say "R" or "S" for normal
- CRC use - now you have the same commands for MODM700. Finally the more
- advanced RCPM systems now use the XMODEM90 series, which tell you how
- long you have been on the system as soon as the file transfer is done.
- You can see this with the older programs when using "RT" but it is now
- automatic with only the standard "R".
-
- To accomodate those who want to return automatically to the command
- mode instead of terminal mode, there is now "RJ" or "SJ". (Of course
- you can easily type a CTL-E if you want to go from terminal mode to
- command mode after the transfer is done.)
-
- For those who are used to using the "RT" and "ST" and don't care
- for the "R" or "S", here is how to "UNDO-J" to return to the older
- method requiring "RT" or "ST" to go to terminal mode upon file
- completion. This modification defeates the feature added in MDM730.

- 2AFB CA to C2
- 4952 4A to 54
- 495F 4A to 54

- ----------------------------------
- SUMMARY:
-
- Using the linking method just one time will have you wondering
- why it was never offered "years ago". For example to call Compuserve
- you might have two numbers, one which is usually busy but is local and
- the second which is seldom busy but is weaker. You could use:
-
- B>>COMMAND: CAL D/C
-
- which calls your favorite (often busy) number first then tries the second
- one automatically.
