; 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.
