; MXO-MD11.ASM - Morrow Micro Decision overlay file for MEX10. 05/15/84 ; ; 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 Morrow Micro Decision computer to the mex pro- ; gram. While this computer has two serial ports, one is used for the ; CRT/keyboard and the other for the printer. ; Connect the modem in place of the printer. ; ;NOTE: This version MXO-MD11 is updated for the Morrow MD-3A ;which has a parallel printer port. If the parallel port is used ;for the printer, no printer changes are necessary. ALSO the ;address in the CONOUT: routine has been corrected. Use version ;-MD10 if your unit is not an MD-3A with the parallel printer port ; ; ; 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. ; ; = = = = = = = = = = = = = = = = = = ; ; 05/15/84 - Converted from MDM7xx to MEX10 - Sandy Berger ; 03/25/84 - Revised for use with MDM730 - Sandy Berger ; 11/11/83 - Renamed to M7MD-1.ASM, no changes - Irv Hoff ; 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 ; 05/28/84 - Altered for model MD-3A - Alan Bierbaum ; ; = = = = = = = = = = = = = = = = = = ; BELL: EQU 07H ;bell CR: EQU 0DH ;carriage return ESC: EQU 1BH ;escape LF: EQU 0AH ;linefeed ; YES: EQU 0FFH NO: EQU 0 ; ; Set to NO if using an MD2 MD3: EQU YES ; PORT: EQU 0FEH ;Morrow MD printer port MODCTL1: EQU PORT+1 ;Modem status port MODDATP: EQU PORT ;Modem data port MODCTL2: EQU PORT+1 ;Modem control port MODRCVB: EQU 02H ;Modem receive bit MODRCVR: EQU 02H ;Modem receive ready MODSNDB: EQU 01H ;Modem send bit MODSNDR: EQU 01H ;Modem send ready bit ; ; MEX service processor stuff ; INMDM EQU 255 ;get char from port to A, CY=no more in 100 ms TIMER EQU 254 ;delay 100ms * reg B TMDINP EQU 253 ;B=# secs to wait for char, cy=no char CHEKCC EQU 252 ;check for ^C from KBD, Z=present SNDRDY EQU 251 ;test for modem-send ready RCVRDY EQU 250 ;test for modem-receive ready SNDCHR EQU 249 ;send a character to the modem (after sndrdy) RCVCHR EQU 248 ;recv a char from modem (after rcvrdy) LOOKUP EQU 247 ;table search: see CMDTBL comments for info PARSFN EQU 246 ;parse filename from input stream BDPARS EQU 245 ;parse baud-rate from input stream SBLANK EQU 244 ;scan input stream to next non-blank EVALA EQU 243 ;evaluate numeric from input stream LKAHED EQU 242 ;get nxt char w/o removing from input GNC EQU 241 ;get char from input, cy=1 if none ILP EQU 240 ;inline print DECOUT EQU 239 ;decimal output PRBAUD EQU 238 ;print baud rate ; 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.
