; M7FA-2.ASM Franklin ACE overlay file for MDM7xx. 07/12/84
;
; This overlay file enables Franklin ACE computers with the Dual
; Interface Card and external modem to use the MDM7xx phone modem program.
;
;************************************************************************
;* *
;* TESTED <<ONLY>> UP TO MDM740 *

;
; 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.
; Much of the information contained here is not in the MDM7xx.ASM file.
;
; Edit this file for your preferences then follow the "TO USE:" example.
;
; Use the "SET" command to change the baudrate when desired.
;
;---------------------------------------------------------------------
;
; 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
; yy00 0100
; -IM7FA-2.HEX (note the "I" command)
; -R ("R" loads in the .HEX file)
; NEXT PC
; yy00 0000
; -G0 (return to CP/M)
; A>SAVE 73 MDM7xx.COM (now have a modified .COM file)
