; M7S1-1.ASM - Sanyo MBC-1100 Overlay file for MDM7xx - 06/01/84 ; ; 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 adapts the Sanyo MBC-1100 computer to the modem program. ; ; NOTE: To use this overlay, you must set the internal jumper for 1200 ; baud on the RS232 card. ; ; Edit this file for your preferences then follow the "TO USE:" example ; shown below. ; ; 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: ; ;============================================================================= ; ;NOTE: The use of the MDMLNK.COM utility makes the following process much ; simpler. You may want to use MDMLNK if it is available to you. ; ;============================================================================= ; ; A>DDT MDM7xx.COM ; DDT VERS 2.2 ; NEXT PC ; 4A00 0100 ; -IM7xx-x.HEX (note the "I" command) ; -R ("R" loads in the .HEX file) ; NEXT PC ; 4A00 0000 ; -G0 (return to CP/M) ; A>SAVE 73 MDM7xx.COM (now have a modified .COM file) ; ; = = = = = = = = = = = = = = = = = = ; ; 06/01/84 - Changed to work with MDM740 - Robert Flagg ; 02/18/84 - Revised for Sanyo MBC-1100 - Jim Shea ; 11/11/83 - Renamed to M7SY-1.ASM, no changes - Irv Hoff ; 09/12/83 - Revised for 300 and 1200 BAUD - Tim Chiaretto ; 07/21/83 - Renamed for use with MDM712 - Irv Hoff ; 07/01/83 - Revised for use with MDM711 - Irv Hoff ; 06/22/83 - Revised for use with MDM710 - Irv Hoff ; 06/22/83 - Altered MDM708DP for Morrow ; Micro Decision computers using ; an external modem - Irv Hoff ; ; = = = = = = = = = = = = = = = = = = ; BELL: EQU 07H ;bell CR: EQU 0DH ;carriage return ESC: EQU 1BH ;escape LF: EQU 0AH ;linefeed ; YES: EQU 0FFH NO: EQU 0 ; ; PORT: EQU 0DDH MODCTL1: EQU PORT ;Modem status port MODDATP: EQU PORT-1 ;Modem data port MODCTL2: EQU PORT ;Modem control port ; ; ORG 100H ; DS 3 ;(for "JMP START" instruction) ; PMMIMODEM: DB NO ;yes=PMMI S-100 Modem 103H AUTODIAL: DB NO ;yes=HAYES Smartmodem, no=non-Hayes 104H TOUCHPULSE: DB 'T' ;T=touch, P=pulse (Smartmodem-only) 105H CLOCK: DB 40 ;clock speed in MHz x10, 25.5 MHz max. 106H ;20=2 MHh, 37=3.68 MHz, 40=4 MHz, etc. MSPEED: DB 1 ;0=110 1=300 2=450 3=600 4=710 5=1200 107H ;6=2400 7=4800 8=9600 9=19200 default BYTDLY: DB 5 ;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.
