;
; 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
