- ;
- ; 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 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
