; MXO-AL10.ASM -- ALTOS SERIES 5 overlay file for MEX10. 05/26/84 ; ; 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 ALTOS SERIES 5 computers to MEX10. ; ; This uses the CPMSETUP.COM file that came with your ALTOS SERIES 5. ; ; First run CPMSETUP and set the printer (serial) for 300 baud. This ; will write the boot track data so every time you boot that disk your ; serial port is set for 300 baud. Do the same for 1200 baud mode and ; boot as needed. Use port labled J9 (far right) on the back of the ; Altos (DP25). Remember the J9 port is wired as a modem port so you ; will need to rewire the modem cable to the correct pins (data out to ; data receive, pins 2 and 3 and CTS -- clear to send, etc...). ; ; 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 MLOAD to overlay the the results ; of this program to the original .COM file. ; ; = = = = = = = = = = = = = = = = = = ; 05/26/84 - MEXified the overlay. - Biff Bueffel ; 11/11/84 - Renamed to M7AL-1.ASM, no changes - Irv Hoff ; 07/27/83 - Renamed to work with MDM712 - Irv Hoff ; 07/17/83 - Revised to work with MDM711 - Irv Hoff ; 07/02/83 - Modified MDM710XE for ALTOS ; SERIES 5 computers with external ; modem - Jeff King ; ; = = = = = = = = = = = = = = = = = = ; BELL: EQU 07H ;bell CR: EQU 0DH ;carriage return ESC: EQU 1BH ;escape LF: EQU 0AH ;linefeed ; YES: EQU 0FFH NO: EQU 0 ; ; MEX service processor stuff ; MEX EQU 0D00H ;address of the service processor 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 ; PRINT EQU 9 ;MEX/BDOS print-string function call ; PORT: EQU 1EH ;ALTOS SERIES 5 serial output port MODCTL1: EQU PORT+1 ;Modem control port MODDATP: EQU PORT ;Modem data port MODCTL2: EQU PORT+1 ;Modem status port MODRCVB: EQU 01H ;Your bit to test for receive MODRCVR: EQU 01H ;Your value when receive ready MODSNDB: EQU 04H ;Your bit to test for send MODSNDR: EQU 04H ;Your value when send ready ; ; ORG 100H ; ; ; Change the clock speed to suit your system ; DS 3 ;(for "JMP START" instruction) ; DB NO ;yes=PMMI S-100 Modem 103H DB NO ;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 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.
