; MXO-EP12.ASM -- Epson QX-10 overlay file for MEX11. 08/25/84 ; ; Changed call locations in sysver for 1.1 -- jw 08/25/84 ; ; Update to add 8/7 bit, even/no parity option to baud rate setting. ; Initial screen change. -- jw 07/11/84 ; ; This is essentially Biff Bueffel's MEX overlay which I have modified ; to correct a few minor bugs, add more allowable baud rates to the ; SET command for null-modem transfers, and change a few initialization ; parameters and comments to reflect the requirements of some local ; BBS's. You may notice some old carry-overs from the MDM7xx series ; overlays, however, these carry-overs will simply be ignored by MEX. ; ; Updated / Upgraded 06/07/84 -- J. L. Bewley (Rev. JLB-1) ; Mile High Epson User's Group -- Denver, Colo. ; Updated to incorporate MEXNEWS.001,001,003 06/13/84 (Rev. JLB-2) ; ; ; This overlay is used to adapt the MEX10.COM program to the Epson ; QX-10 computer using an external Hayes Smartmodem (tm) or compatible ; modem attached to the QX-10's serial port. It will NOT work with ; the internal Comrex Communicator modems. ; ; For this overlay to work properly, the DIP switches behind ; the front panel on the Hayes should be set as follows: ; ; Switch: ; #1 #2 #3 #4 #5 #6 #7 #8 ; UP UP DN UP DN UP DN DN ; ; It is especially important that Switch #1 be set UP to enable ; disconnect by DTR. In general, these switch settings are ; compatible with Valdocs usage. ; ; 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 QX-10 computer to the modem program. ; ; 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. ; Also, this revision has been set to start out in the CHECKSUM mode ; to be compatible with TBBS, some RBBS, and other older BBS software ; which does not support the CRC mode. If you desire the CRC mode ; default, simply change the CRCDFLT to TRUE below and reassemble, ; or, within MEX, use the STAT command to set CRC ON and CLONE your ; copy of MEX. Use SET to change baud rate and CLONE for new start 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. ; ; = = = = = = = = = = = = = = = = = = ; 07/11/84 - Changed SET routine, initial scrn - Jim Wright ; 06/13/84 - Customized Biff Bueffel's overlay - Jim Bewley ; 05/24/84 - MEXified the overlay - Biff Bueffel ; 11/11/83 - Renamed to M7EP-1.ASM, no changes - Irv Hoff ; 08/27/83 - Revised to work with MDM712 - Irv Hoff ; 07/25/83 - Changed M710XE.ASM forEpson QX-10 - Phil Becker ; ; = = = = = = = = = = = = = = = = = ; BELL: EQU 07H ;bell CR: EQU 0DH ;carriage return ESC: EQU 1BH ;escape LF: EQU 0AH ;linefeed ; YES: EQU 0FFH NO: EQU 0 ; BR7A: EQU 7AH ;Baud rate divisors BR7B: EQU 7BH BR4E: EQU 4EH BR4F: EQU 4FH ; ; 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 11H ;Epson QX-10 serial output port MODCTL1: EQU PORT+2 ;Modem control port MODDATP: EQU PORT ;Modem data port MODCTL2: EQU PORT+2 ;Modem control 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 as needed for your system. ; 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 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 1 ;0=0 delay 1=10ms 5=50ms - 9=90ms 108H ;default time to send character in ter- ;minal mode file transfer for slow BBS.
