; M7SSM-2.ASM -- SSM-I/O Board ; ; 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 MDM712.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 1200 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.
