- TOPIC : MDM712 MODEM PROGRAM INSTALLATION INFORMATION
-
- FROM : IRVIN M. HOFF W6FFC
-
- DATE : 07/27/83
-
-
- This program is based on one originally written by Ward Christ-
- ensen in September 1977. It has since undergone a considerable number
- of changes. Recent changes include auto-dialing and continuous redial-
- ing for the Hayes 300 or 1200 Smartmodem and the U. S. Robotics, along
- with the standard PMMI 103 routines the program has long supported. It
- also handles up to two alternate long distance systems such as SPRINT,
- ALLNET, MCI, (can be used to auto-dial TYMNET), etc.
-
-
- NOTE: Special configuration files are being added for specific types of
- computers. A large number are already available (as shown below)
- and others are being added as interest escalates. This file will
- be updated accordingly.
-
- To adapt this version to your equipment, you will want to get
- some of the following programs:
-
- Program name Purpose
-
- MDM712.ASM (source code file)
- MDM712.COM (object code file)
- MDM712.DOC (how-to-use file)
- MDM712.INF (information file)
- M712AC.ASM (AppleCat II overlay file)
- M712AL.ASM (Altos Series 5 overlay file)
- M712AP.ASM (Apple II overlay file)
- M712DP.ASM (Datapoint 1560 overlay)
- M712GP.ASM (General purpose overlay)
- M712H8.ASM (Heath/Zenith H89 file)
- M712HP.ASM (Hewlett Packard 125 file)
- M712HZ.ASM (Heath/Zenith Z-100 file)
- M712I2.ASM (Interfacer 3/4 overlay file)
- M712KP.ASM (KayPro overlay file)
- M712MD.ASM (Morrow MD overlay file)
- M712MM.ASM (Morrow Multi I/O overlay file)
- M712NE.ASM (NEC PC-8001 overlay file)
- M712NM.ASM (Phone number overlay, ALD information)
- M712OS.ASM (Osborne OS-1 overlay file)
- M712OT.ASM (Otrona Attache overlay file)
- M712OX.ASM (Osborne Executive overlay file)
- M712PM.ASM (PMMI S-100 modem overlay)
- M712TV.ASM (TeleVideo TS-802 overlay)
- M712XE.ASM (Xerox 820 overlay file)
- M712ZB.ASM (Telcon ZORBA overlay file)
-
-
- (The minimum would be any pair in one of the examples shown
- below.)
-
- There are several ways by which you can set the proper ports,
- status pin values, etc. for your equipment.
-
-
- 1) Use your editor, ASM (or MAC) MDM712.COM and
- and DDT (or SID) with: M712xx.ASM
-
- (712xx stands for an appropriate overlay)
- or
- 2) Use your editor, ASM (or MAC) MDM712NASM
-
-
- One of those should appeal to you. The program is designed to
- work immediately for PMMI users with no changes - just use MDM712.COM.
- (You might wish to change some of the available options, however. It
- is set to use base port 0C0H.)
-
- When ready to use the program, type 'H' (for 'HELP'), hit RET
- and it will display helpful information on the commands. There are so
- many commands there are several pages. You can abort the display with
- a CTL-C. (One of the most useful features being CTL-P to toggle your
- printer on/off.) You can also type a question mark (?) which shows the
- current parameters.
-
- The program has received numerous worthwhile optional features
- in the past several months.
-
-
- SUPPLEMENTAL INFORMATION OF INTEREST:
-
- When adapting the program to your equipment, this table might be
- helpful:
-
- (A typical port number will be shown for each.)
-

-
- PORT (control or status) 0C0H 29H 0EDH 0D8H+5
- BAUDRP (baud rate port) PORT+2 --- --- ---
- MODCTL1 (control or status) PORT PORT PORT PORT
- MODCTL2 (2nd control port) PORT+3 --- --- ---
- MODDATP (data port) PORT+1 PORT-1 PORT-1 PORT-5
- MODRCVB (receive bit) 02H 02H 02H 01H
- MODRCVR (receive ready) 02H 02H 02H 01H
- MODSNDB (send buffer empty bit) 01H 01H 01H 20H
- MODSNDR (send ready) 01H 01H 01H 20H
