There are a number of ; options that you can use to configure the program to suit your taste. ; This file adapts the Otrona Attache computer to MEX10. ; ; ; Edit this file for your preferences then follow the "TO USE:" example ; shown below. ; ; Use the SET command to change baud rate if needed. This updates the ; CMOS RAM value. When the program is first called used, the baud rate ; is the same as currently set by the Valet function. ; ; TO USE: First edit this file filling in answers for your own ; equipment. Then assemble with ASM.COM or equivalent ; assembler. Then use MLOAD21.COM (or later) to combine ; this overlay with the original MEX10.COM file. You may ; optionally combine files for Hayes Smartmodem (MXO-SM11. ; HEX), Version 1.0C MEX update (MEXFIX.HEX), and buffer size ; customization (MEXPAT10.HEX) on the same MLOAD command line ; if you desire. See MEX10.DOC or MEX-EASY.DOC for details. ; For example, to prepare a working COM file for use with a ; Hayes Smartmodem and to incorporate the version 1.0C from ; MEXNEWS.003, enter the following: ; ; A>MLOAD21 MEX-OA10.COM=MEX10.COM,MXO-OA,MXO-SM11,MEXFIX ; ; >>>> report any bugs to marin rcpm 415-383-0473 (Attache Users <<<< ; >>>> Newsletter source) or fortfone rcp/m 414-563-9932 <<<<<<<<<<<< ; ; = = = = = = = = = = = = = = = = = = ; 08/12/84 - Modified sign-on screen/patched ; for no-hang-up with exit - Phil Oyer ; 06/15/84 - MEXified overlay - Rad Collins ; 01/16/84 - Modified for new BIOS in CP/M 2.2.5 ; and added 2400,4800 BPS options - Donald Larson ; 11/11/83 - Renamed to M7OA-1.ASM, no changes - Irv Hoff ; 09/01/83 - Updated to work with MDM712 - Irv Hoff ; 08/27/83 - Added optional BIOS patch - Arley Dealey ; 06/30/83 - Revised to work with Otrona - Arley Dealey ; 06/22/83 - Revised to work with MDM710 - Irv Hoff ; 05/27/83 - Updated to work with MDM709 - Irv Hoff ; 05/15/83 - Revised to work with MDM708 - Irv Hoff ; 04/11/83 - Updated to work with MDM707 - Irv Hoff ; 04/04/83 - Updated to work with MDM706 - Irv Hoff ; 03/03/83 - Modified MDM705KP for XEROX ; 820-II computers with external ; modems - David Wurz ; ; = = = = = = = = = = = = = = = = = = ; ; YES: EQU 0FFH NO: EQU 0 ; ; BDOS EQU 005H BELL: EQU 07H ;bell CR: EQU 0DH ;carriage return ESC: EQU 1BH ;escape LF: EQU 0AH ;linefeed WARMSTART: EQU 0000H ; ; 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 ; ; PORT: EQU 0F0H ;Otrona Attache modem 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) ; 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.
