; M7AP-1.ASM Apple overlay file for MDM7xx. 11/11/83 ; ; This overlay file enables Apple II computers with the Apple Super ; Serial card and external modem to use the MDM7xx phone modem program. ; It also supports the following Apple modem configurations: ; ; a) CCS 7710 serial interface and external modem ; b) SSM serial interface and external modem ; c) Apple communications interface and external modem ; d) Mountain Hardware CPS Multifunction card and external modem ; ; 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. ; Much of the information contained here is not in the MDM7xx.ASM file. ; ; Edit this file for your preferences then follow the "TO USE:" example. ; ; Use the "SET" command to change the baudrate when desired. It starts ; out at 300 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 ; 4300 0100 ; -IM7AP-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 M7AP-1.ASM, no changes - Irv Hoff ; 10/07/83 - Added CPS card support - Wally Hubbard ; 07/27/83 - Renamed to work with MDM712 - Irv Hoff ; 07/01/83 - Revised to work with MDM711 - Irv Hoff ; 06/22/83 - Revised to work with MDM710 - Irv Hoff ; 05/27/83 - Updated to work with MDM709 - Irv Hoff ; 05/15/83 - Revised to work with MDM708 - Irv Hoff ; 04/11/83 - Updated to work with MDM707 - Irv Hoff ; 04/04/83 - Updated to work with MDM706 - Irv Hoff ; 02/27/83 - Updated to work with MDM705 - Irv Hoff ; 02/12/83 - Used MDM703CF to make this file ; for Apple computers using a var- ; iety of serial interface cards ; with external modem. - Bruce Kargol ; ; = = = = = = = = = = = = = = = = = ; BELL: EQU 07H ;bell CR: EQU 0DH ;carriage return ESC: EQU 1BH ;escape LF: EQU 0AH ;linefeed ; YES: EQU 0FFH NO: EQU 0 ; ; CCS: EQU NO ;YES for CCS 7710 COMCARD: EQU NO ;YES for Apple comcard SSC: EQU NO ;YES for Super Serial Card SSM: EQU NO ;YES for SSM serial card CPS: EQU YES ;YES for CPS card ; IF CCS MODDATP: EQU 0E0A1H ;data port of CCS 7710 MODCTL1: EQU 0E0A0H ;status port of CCS 7710 ENDIF ;endif CCS ; IF COMCARD MODDATP: EQU 0E0AFH ;data port of Comcard MODCTL1: EQU 0E0AEH ;status port of Comcard ENDIF ;endif Comcard ; IF SSM MODDATP: EQU 0E0A5H ;data port of SSM MODCTL1: EQU 0E0A4H ;status port of SSM ENDIF ;endif SSM ; IF SSC MODDATP: EQU 0E0A8H ;data port of Apple Super Serial Card MODCTL1: EQU 0E0A9H ;modem status port of Super Serial Card MODRCVB: EQU 08H ;bit to test for received data MODRCVR: EQU 08H ;modem receive ready MODSNDB: EQU 10H ;bit to test for ready to send MODSNDR: EQU 10H ;modem send ready bit ENDIF ;endif SSC ; ; ; (Any slot with any CPS function assigned to it may be used.) ; IF CPS SLOT: EQU 2 ;Slot = 1 or 2 for normal CP/M.
