- ; M7EP-2.ASM -- Epson QX-10 overlay file for MDM7xx. 06/01/84
- ;
- ; 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 QX-10 computer to the modem program. 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
- ; shown below.
- ;
- ; 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:
- ;
- ;
- ;=============================================================================
- ;
- ; SPECIAL NOTE: The MDMLNK.COM utility, if available to you, will
- ; overlay the .HEX file on the .COM file in one simple step.
- ; See MDMLNK instructions for further details.
