; M7NH-2.ASM -- North Star Horizon - HSIO-4 overlay file for MDM7xx. 01/14/84
;
; This overlay adapts the MDM7xx program to the North Star Horizon
; HSIO-4 serial I/O board. It uses the 8251 USART.
;
; 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.
; It supports all the baud rates that the HSIO-4 supports even
; when it is not likeley you are running a dial up modem at that
; speed. I.E. 19200 baud. This still could be useful for a direct
; connection between two systems though.
;
; 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:
;
; A>DDT MDM7xx.COM
; DDT VERS 2.2
; NEXT PC
; 4300 0100
; -IM712GP.HEX (note the "I" command)
; -R ("R" loads in the .HEX file)
; NEXT PC
; 4300 0000
; -G0 (return to CP/M)
; A>SAVE 66 MDM712.COM (now have a modified .COM file)
;
; use A>SAVE 68 MDM715.COM for ver 7.15 and
; A>SAVE 69 MDM716.COM for ver 7.16
; Check the .DOC files for other versions.
