TOPIC : MDM711 MODEM PROGRAM INSTALLATION INFORMATION
FROM : IRVIN M. HOFF W6FFC
DATE : 07/01/83
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 supported since its
inception.
NOTE: Special configuration files are being added for specific types of
computers. Several are available as shown below. Others will be
provided for popular computers using external modems. 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 Squeezed Name Purpose
MDM711.ASM MDM711.AQM (source code file)
MDM711.COM MDM711.OBJ (object code file)
MDM711.DOC MDM711.DQC (how-to-use file)
MDM711.INF MDM711.IQF (information file)
MDM711AC.AQM MDM711AC.AQM (AppleCat II overlay file)
MDM711AP.ASM MDM711AP.AQM (Apple II overlay file)
MDM711DP.ASM MDM711DP.AQM (Datapoint 1560 overlay)
MDM711GP.ASM MDM711GP.AQM (General purpose overlay)
MDM711H8.ASM MDM711H8.AQM (Heath/Zenith H89 file)
MDM711HZ.ASM MDM711HZ.AQM (Heath/Zenith Z-100 file)
MDM711KP.ASM MDM711KP.AQM (KayPro overlay file)
MDM711MD.ASM MDM711MD.AQM (Morrow MD overlay file)
MDM711NE.ASM MDM711NE.AQM (NEC PC-8001 overlay file)
MDM711NM.ASM MDM711NM.AQM (Phone number overlay)
MDM711OS.ASM MDM711OS.AQM (Osborne overlay file)
MDM711PM.ASM MDM711PM.AQM (PMMI S-100 modem overlay)
MDM711TV.ASM MDM711TV.AQM (TeleVideo TS-802 overlay)
MDM711XE.ASM MDM711XE.AQM (Xerox 820 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) MDM711.COM and
and DDT (or SID) with: MDM711xx.ASM
(711xx stands for an appropriate overlay)
or
2) Use your editor, ASM (or MAC) MDM711.ASM
One of those should appeal to you. The program is designed to
work immediately for PMMI users with no changes - just use MDM711.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.)
PMMI UART 8251 2661 8250
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
(1 For a PMMI board with UART for a typical S-100 computer)
(2 For a non-PMMI computer using a 8251A to external modem)
(3 For a Heath/Zenith Z-100 computer using the 2661B I/O
(4 For a Heath/Zenith Z-19 or Z-89 using the 8250 I/O
