; MDM711AP.ASM Apple overlay file for MDM711. 07/01/83 ; ; This overlay file enables Apple II computers with the Apple Super ; Serial card and external modem to use the MDM711 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 ; ; 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 MDM711.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 MDM711.COM ; DDT VERS 2.2 ; NEXT PC ; 4300 0100 ; -IMDM711AP.HEX (note the "I" command) ; -R ("R" loads in the .HEX file) ; NEXT PC ; 4300 0000 ; -G0 (return to CP/M) ; A>SAVE 66 MDM711.COM (now have a modified .COM file) ; ; = = = = = = = = = = = = = = = = = = ; ; 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 yes ;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 ; IF CCS MODDATP: EQU 0E091H ;data port of CCS 7710 MODCTL1: EQU 0E090H ;status port of CCS 7710 ;changed to match slot #1 instead of slot 2 addresses. add 10h per slot. ;starting with slot 0 = 0e00h for cp/m 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 ; ; ; Apple status bit equates for CCS, Comcard and SSM ; IF NOT SSC MODSNDB: EQU 02H ;bit to test for send MODSNDR: EQU 02H ;value when ready MODRCVB: EQU 01H ;bit to test for receive MODRCVR: EQU 01H ;value when ready ENDIF ;not SSC ; ; ; We have software control over the Super Serial Card so allow INITMOD ; SETUPR routines. ; ; ORG 100H ; ; ; Change the clock speed to match your equipment ; DS 3 ;(for "JMP START" instruction) ; PMMIMODEM: DB NO ;yes=PMMI S-100 Modem 103H SMARTMODEM: DB NO ;yes=HAYES Smartmodem, no=non-pmmi 104H TOUCHPULSE: DB 'T' ;T=touch, P=pulse (Smartmodem-only) 105H CLOCK: DB 20 ;clock speed in MHz x10, 25.5 MHz max. 106H ;20=2 MHh, 37=3.68 MHz, 40=4 MHz, etc. MSPEED: DB 5 ;0=110 1=300 2=450 3=600 4=710 5=1200 107H ;6=2400 7=4800 8=9600 9=19200 default BYTDLY: DB 1 ;0=0 delay 1=10ms 5=50 ms - 9=90 ms 108H ;default time to send character in ter- ;minal mode file transfer for slow BBS.
