- ;M8MCDOS.A86 -- Overlay file for the CompuPro I3/I4 under MC-DOS 11/22/84
- ;
- ;
- ; This overlay adapts the MDM8xx program to the CompuPro under MC-DOS. This
- ; Overlay makes use of the special function call 6 used by the Gifford XIOS.
- ;
- ; 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
- ; is connected to a serial port. This includes acoustic modems as well
- ; as "intelligent" modems such as the Hayes Smartmodem, Racal-Vadic, Bell
- ; Dataphone 212A, etc.
- ;
- ; This overlay is capable of setting the baud rate, disconnecting the
- ; modem, and sending breaks.
- ;
- ;
- ;
- ;=========================================================================
- ; <<< N O T E >>>
- ; This version does not yet make use of the DELAY system function. A future
- ; version will overlay the timing loops in MDM840 and call the CCPM system
- ; delay function. THEREfore set the Clock rate to 10 Mhz so that the loops
- ; execute fast enough.
- ;
- ; Leave the console in the TTYS file. And turn the ECHO switch off on the
- ; SmartModem to avoid Feedback with the Gifford Login routine. I use the
- ; Following Hayes 1200 switch settings:
- ;
- ; +---+---+---+---+---+---+---+---+

- ; TO USE: First edit this file filling in answers for your own
- ; equipment. Then assemble with ASM86.CMD or equivalent
- ; assembler. Then use PIP to append the results
- ; of this program to the original MDM8xx.H86 file:
- ;
- ; ASM86 M8MCDOS
- ; PIP MDM.H86=MDM830.H86,M8MCDOS.H86
