; 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) ; ; = = = = = = = = = = = = = = = = = = ; ; 04/26/84 - Modified to take further advantage of the software selectable ; features provided by CompuPro - Chuck Rider ; 11/20/83 - Interfacer 4 Note Added - A.W.
