- ; M7DP-1.ASM -- Datapoint 1560 overlay file for MDMxx2. 11/11/83
- ;
- ; 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 adapts the Datapoint 1560 computer to the modem program.
- ; Much of the information contained here is not in the main file.
- ;
- ; Edit this file for your preferences then follow the "TO USE:" example
- ; shown below.
- ;
- ; Use the MDM7xx "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
- ; -IM7DP-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)
