; M7IN-3.ASM -- Overlay file for the CompuPro I3/I4/SS1. 4/26/84
;
; This overlay adapts the MDM7xx program to the CompuPro Interfacer 3 or
; Interfacer 4 or System Support 1 serial cards using the 2651 USART chip.
; (Note: It is very easy to modify this file to work with the Apple CPS
; Multifunction card too.)
;
; NOTE TO INTERFACER 4 USERS:
; The 'MIDDLE' serial port and the Centronics port can have their addresses
; changed using a hardware option. Godbout did this to maintain software
; compatibility with their bios. In order to prevent problems, use the
; 'RIGHT' serial port (RELATIVE USER 5) instead of the center serial
; port (RELATIVE USER 6). Also, read page 19 of the manual, the modem
; port will probably have to be set up in the 'MASTER MODE'. While
; you're reading the manual, read the section on 'WAIT STATE LOGIC'.
; I'm using a CPU-Z running at 6Mhz, with a 300 baud modem and two wait
; states (jumper at J7). Without them, I get 'o's for 'n's and 'g's
; for 'f's, and the checksums are never right. (AWW 12/20/83)
;
; You will want to look this file over carefully. There are a number of
; options that you can use to configure the program to suit your taste.
; This file places particular emphasis on using an external modem that
; is connected to a serial port. This includes acoustic modems as well
; as "intelligent" modems such as the Hayes Smartmodem, Racal-Vadic, Bell
; Dataphone 212A, etc.
;
; This overlay is capable of changing the UART port number, setting the
; baud rate and parameters, disconnecting the modem, and sending breaks.
;
;
; TO USE: First edit this file filling in answers for your own
; equipment. Then assemble with ASM.COM or equivalent
; assembler. Then use DDT to overlay the the results
; of this program to the original .COM file:
;
; A>DDT MDM7xx.COM
; DDT VERS 2.2
; NEXT PC
; 4B00 0100
; -IM7IN-2.HEX (note the "I" command)
; -R ("R" loads in the .HEX file)
; NEXT PC
; 4B00 0000
; -G0 (return to CP/M)
; A>SAVE 74 MDM7xx.COM (now have a modified .COM file)
