TOPIC : INFORMATION FILE FOR INSTALLING THE MODEM797 TELEPHONE PROGRAM
FROM : IRVIN M. HOFF and PAUL L. KELLEY
DATE : 17 DEC 82
REVISED: 24 DEC 82 by Bruce R. Ratoff
The MODEM7 program was originally written by Ward Christensen
in Sept. 1977. It has since undergone a considerable number of changes.
MODEM797.HIS (for history) contains a list of those changes.
The current version is 7.97 as of 24-DEC-82. To adapt this
version to your equipment, you will want to get some of the following
programs:
Program name Squeezed Name Purpose
MODEM797.ASM (MODEM797.AQM) (source code file)
MODEM797.COM (MODEM797.OBJ) (object code file)
MODEM797.HIS (MODEM797.HQS) (history file)
MODEM797.INF (MODEM797.IQF) (information file)
MODEM797.LIB (MODEM797.LQB) (library file)
MODEM797.SET (MODEM797.SQT) (how to set file)
MCNFG797.ASM (MCNFG797.AQM) (general overlay file)
MCOSB797.ASM (MCOSB797.AQM) (Osborne overlay file)
(The minimum would be any pair in one of the examples shown
below.)
There are numerous ways by which you can set the proper ports,
status pin values, etc. for your equipment.
1) Use DDT, SID or DUU with: MODEM797.COM and
MODEM797.SET
or
2) Use your editor, ASM, MODEM797.COM and
and DDT or SID with: MCNFG797.ASM
(Osborne owners use MCOSB797.ASM not MCNFG797.ASM)
or
3) Use your editor, and MAC with: MODEM797.ASM and
MODEM797.LIB
One of those should appeal to you. Possibly the first suggest-
ion is the easiest to use.
After asking for the program, type 'H', hit RET and it will
display helpful information on the commands. There are so many commands
there are several pages.
The program has received numerous worthwhile optional features
in the past several months.
SUPPLEMENTAL INFORMATION OF INTEREST:
If using your editor with MCNFG797.ASM or MODEM797.ASM,
the following might be helpful:
(A typical port number will be shown for each.)
PMMI UART 8251 2661 8250
PORT (control or status) 0C0H 31H 0EDH 0D8H+5
BAUDRP (baud rate port) PORT+2 --- --- ---
MODCTL2 (2nd control port) PORT+3 --- --- ---
MODCTLP (control or status) PORT PORT PORT PORT
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
(The 2661 information is for a typical Heath/Zenith Z-100
series computer. The 8250 information for a typical Heath/Zenith
H8 or H89 computer. The first PMMI board with UART for a typical
S-100 computer.)
