; ; MXO-MR10.ASM - Morrow Micro Decision MD-11 overlay file for MEX ; or MDM712. ; 6/28/84 ; ; (Adapted from M712MD.ASM, originally for Morrow MD-2 & MD-3) ; ; 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 either modem program to the Morrow MD-11 computer. ; (It is not for use with the Morrow MD-2 or MD-3 computers.) ; While this computer has a number of serial ports, one is used for the ; terminal and the another for the printer/modem. To use this ; overlay, you must use the CP/M program "SETUP" to set the printer/ ; modem port to 1200 baud. (This is usually done automatically upon ; a boot.) Configure the internal jumpers to make the port a DTE ; type of device (page D-16 in my MD-11 User's Guide) for use with ; modems. ; ; 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 1200 baud when the program is first called up. If you exit ; the program while at 300 baud, re-boot the Morrow before proceeding ; in order to reprogram the Zilog DART to the correct clock ratio. ; (The SET command alters the DART clock divide ratio, not the ; clock frequency itself). Exiting the program when set to 1200 ; baud causes no such concern. (This advice only applies to usage ; of the SET command). ; ; 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 on the original MDM712.COM file (or ; follow the instructions with MEX to overlay MEX10.COM). ; ; For MDM712: ; ; A>SAVE ; A>DDT MDM712.COM ; DDT VERS 2.2 ; NEXT PC ; 4300 0100 ; -IMXO-MR10.HEX (note the "I" command) ; -R ("R" loads in the .HEX file) ; NEXT PC ; 4300 0000 ; -G0 (that's a zero: return to CP/M) ; ; CP/M 3 SAVE - Version 3.0 ; Enter file (type RETURN to exit): MODEM7.COM ; Beginning hex address 0100 ; Ending hex address 4300 ; A> ; ; You now have MODEM7.COM (or MEX.COM) for use on the ; Morrow MD-11. ; ; ; = = = = = = = = = = = = = = = = = = ; ; 06/28/84 - Further revisions & renamed for MEX- Steve Reyer ; 05/28/84 - Revised for use on Morrow MD-11 - Steve Reyer ; 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 62H ;Morrow MD-11 prt/modem port MODCTL1: EQU PORT+1 ;Modem status port MODDATP: EQU PORT ;Modem data port MODCTL2: EQU PORT+1 ;Modem control port ; ; The following was added by Reyer to define the Zilog DART ; MODSNDB: EQU 04H ;bit to test for send MODSNDR EQU 04H ;value when ready MODRCVB EQU 01H ;bit to test for recv MODRCVR EQU 01H ;value when ready ; ; ORG 100H ; DS 3 ;(for "JMP START" instruction) ; PMMIMODEM: DB NO ;yes=PMMI S-100 Modem 103H SMARTMODEM: DB YES ;yes=HAYES Smartmodem, no=non-PMMI 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 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 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.
