- ; M8GP-1.A86 -- General purpose overlay file for MDM8xx. 09/21/84
- ;
- ; This overlay adapts the MDM8xx program to various serial I/O types
- ; very easily - such as the UART, 8251 USART, 8250 ACE, 2661 EPCI, etc.
- ;
- ; 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 .CMD 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. For Example:
- ;
- ; "IN" CompuPro Interfacer 3/4 overlay using the 2651
- ;
- ; 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 ASM86.CMD or equivalent
- ; assembler. Then use M8CNFG to overlay the the results
- ; of this program to the original MDM8xx.H86 file:
- ;
- ; ASM86 M8IN-1
- ; REN M8OVL.H86=M8IN-1.H86
- ; M8CNFG
- ; GENCMD MDM 8080 CODE[MFF0]
- ;
- ; Now run MDM. Have Fun
