- ; MXO-XR10.ASM -- XOR S-100-4 (Rev B CPU) overlay file for MEX112 10/21/84
- ;
- ; 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.
- ;
- ; 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 MLOAD to overlay the the results
- ; of this program to the original .COM file.
- ;
- ; critical customizations:
- ; PORT - Modem status port for your system
- ; INITMOD1: - optional patch for Modem-7 term-mode
- ; command compatability - MEX112 depend
- ; INITMOD2: - modem port initialization
- ; NEWBAUD: - reads MSPEED: & inits baudrate
- ; SETUPR: - custom SET command to change baud
- ; rate as well as start, stop & data
- ; bit transmission parameters
- ; CLREOS: &
- ; CLRSCR: - terminal command for clearing screen
