- ; MDM711,MDM712 driver for Adds Multivision
- ;
- ;
- ; These files (AUXDVnnn.ASM) are extensions to the overlay set that
- ; is provided with MODEM711 and MODEM712 and should work with both
- ; programs. All of these drivers have not been tested. If you have
- ; any problems or updates, leave a message to me on the Dallas
- ; Metroplex RCPM (214) 739-1935 (evenings and weekends)

- ; 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 places particular emphasis on using an external modem that
- ; does not match one of the other special overlays. You would use the
- ; normal CP/M "Configure" program to set the modem to whatever baud rate
- ; you would normally use (such as 300 or 1200, etc.) Then perhaps just
- ; make a second .COM file if you need both 300 and 1200 and do not wish
- ; to write your own initialization or "set baud" routine.
- ;
- ; You could look at other overlay files to see how the GOODBYE and/or
- ; SETUPR areas are handled. You could then adapt one of those, if ap-
- ; propriate for your equipment in this overlay. Some examples:
- ;
- ; "DP" Datapoint 1560 overlay using 8251 I/O and CTC timers for
- ; setting baud rates
- ; "H8" Heath H89 overlay for 8250 I/O and programmable baud rates
- ; "HZ" Zenith 120 overlay for 2661B initialization and baud rates
- ; "XE" Xerox 820II overlay for Z80-SIO intialization, etc.
- ;
- ; Edit this file for your preferences then follow the "TO USE:" example
- ; shown below.
- ;
- ; 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 to the original .COM file:
- ;
- ; A>DDT MDM711.COM (or MDM712.COM)
- ; DDT VERS 2.2
- ; NEXT PC
- ; 4300 0100
- ; -IAUXDVnnn.HEX (note the "I" command)
- ; -R ("R" loads in the .HEX file)
- ; NEXT PC
- ; 4300 0000
- ; -G0 (return to CP/M)
- ; A>SAVE 66 MDM711.COM (now have a modified .COM file)
