- ; M7IN-3.ASM -- Overlay file for the CompuPro I3/I4/SS1. 4/26/84
- ;
- ; This overlay adapts the MDM7xx program to the CompuPro Interfacer 3 or
- ; Interfacer 4 or System Support 1 serial cards using the 2651 USART chip.
- ; (Note: It is very easy to modify this file to work with the Apple CPS
- ; Multifunction card too.)
- ;
- ; NOTE TO INTERFACER 4 USERS:
- ; The 'MIDDLE' serial port and the Centronics port can have their addresses
- ; changed using a hardware option. Godbout did this to maintain software
- ; compatibility with their bios. In order to prevent problems, use the
- ; 'RIGHT' serial port (RELATIVE USER 5) instead of the center serial
- ; port (RELATIVE USER 6). Also, read page 19 of the manual, the modem
- ; port will probably have to be set up in the 'MASTER MODE'. While
- ; you're reading the manual, read the section on 'WAIT STATE LOGIC'.
- ; I'm using a CPU-Z running at 6Mhz, with a 300 baud modem and two wait
- ; states (jumper at J7). Without them, I get 'o's for 'n's and 'g's
- ; for 'f's, and the checksums are never right. (AWW 12/20/83)
- ;
- ; 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.
- ; This file places particular emphasis on using an external modem that
- ; is connected to a serial port. This includes acoustic modems as well
- ; as "intelligent" modems such as the Hayes Smartmodem, Racal-Vadic, Bell
- ; Dataphone 212A, etc.
- ;
- ; This overlay is capable of changing the UART port number, setting the
- ; baud rate and parameters, disconnecting the modem, and sending breaks.
- ;
- ;
- ; 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
- ; 4B00 0100
- ; -IM7IN-2.HEX (note the "I" command)
- ; -R ("R" loads in the .HEX file)
- ; NEXT PC
- ; 4B00 0000
- ; -G0 (return to CP/M)
- ; A>SAVE 74 MDM7xx.COM (now have a modified .COM file)
