; M7IN-1.ASM -- Overlay file for the CompuPro I3/I4. 11/11/83 ; ; 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.) ; ; 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 setting the baud rate, 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 ; 4300 0100 ; -IM7IN-1.HEX (note the "I" command) ; -R ("R" loads in the .HEX file) ; NEXT PC ; 4300 0000 ; -G0 (return to CP/M) ; A>SAVE 66 MDM7xx.COM (now have a modified .COM file) ; ; = = = = = = = = = = = = = = = = = = ; ; 11/11/83 - Renamed to M7IN-1.ASM, no changes - Irv Hoff ; 07/27/83 - Renamed to work with MDM712 - Irv Hoff ; 07/11/83 - Modifed somewhat for MDM711 - Irv Hoff ; 07/08/83 - Adapted from MDM711GP.ASM - Paul Traina ; ; = = = = = = = = = = = = = = = = = ; BELL: EQU 07H ;bell CR: EQU 0DH ;carriage return ESC: EQU 1BH ;escape LF: EQU 0AH ;linefeed ; YES: EQU 0FFH NO: EQU 0 ; ; Change the following to match your equipment ; GBCI34: EQU YES ;true= Godbout Interfacer 3 or 4 GBCSS1: EQU NO ;true= Godbout SS1 board ; ; = = = = = = = = = = = = = = = = = ; IF GBCI34 BASE: EQU 010H ;base port of CompuPro I3 or I4 cards UPORT: EQU BASE+7 ;user (chip select) port MDM: EQU 6 ;chip that controls modem port ENDIF ; IF GBCSS1 BASE: EQU 05CH ;base of serial section of CompuPro SS1 UPORT: EQU 0EFH ;this should be some UNUSED port on...
