; M7AP-1.ASM Apple overlay file for MDM7xx. 11/11/83
;
; This overlay file enables Apple II computers with the Apple Super
; Serial card and external modem to use the MDM7xx phone modem program.
; It also supports the following Apple modem configurations:
;
; a) CCS 7710 serial interface and external modem
; b) SSM serial interface and external modem
; c) Apple communications interface and external modem
; d) Mountain Hardware CPS Multifunction card and external modem
;
; 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. It starts
; out at 300 baud when the program is first called up.
;
;
; 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
; 4300 0100
; -IM7AP-1.HEX (note the "I" command)
; -R ("R" loads in the .HEX file)
; NEXT PC
; 4300 0000
; -G0 (return to CP/M)
; A>SAVE 66 MDM7xx.COM (now have a modified .COM file)
