; M7-2830.ASM -- CCS-SYSTEM 320/420 or any S-100 Computer using the
; CCS-2830 Dart 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.
;
;
; 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. 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
; 4x00 0100
; -IM7-2830.HEX (note the "I" command)
; -R ("R" loads in the .HEX file)
; NEXT PC
; 4x00 0000
; -G0 (return to CP/M)
; A>SAVE 73 MDM7xx.COM (now have a modified .COM file)

; 04/30/83 - Renamed and revised for MDM7xx - Dennis Recla
;
; 10/29/83 - Modified MDM705XE for CCS-SYSTEM 320/420 and any S-100 type
; computers with the CCS-2830 I/O Board and an external 212A
; (Bell 212A or Hayes Smartmodem 1200) modem.
