- ; Use the "SET" command to change baudrate when desired.
- ;
- ; Edit this file for your preferences then follow the "TO USE:" example
- ; shown below.
- ;
- ;
- ; 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:
