- ; 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)
