; M7P1-1.ASM MODEM7 OVERLAY (MDM712 and later) FOR PMC MICROMATE 101 ; Beta test version 1 ; ; History: ; ; 01/13/84 Revised per M7GP-1.ASM -- the General purpose overlay file ; for MDM7xx dated 11/11/83 and name changed for MDM716 ; Bill Wells, University of California, Berkeley CA. ; 11/01/83 IN$MODDATP modified to output 00H then 10H per page 75 ; of the MicroMate User's Guide (instead of only 10H) ; Bill Wells, University of California, Berkeley CA. ; 10/31/83 BSD Unix communication defaults set by Bill Wells, UCB ; Bill Wells, University of California, Berkeley CA. ; XOFFTST = YES (Unix ports use XON/XOFF) ; CRCDFLT = NO (umodem & tmodem do not have CRC) ; IGNORCTL = NO (so vi, more, & tset work) ; 10/09/83 Modified for MDM712 by Jim Warner, UCSC ; BAUDMATCH routine changed to query user about setting of ; the IGNORCTL.

The hardware is read to determine what that is and ; MSPEED is changed to agree with it. A request for a new BAUD ; rate is translated in Digital Research's official BAUD rate ; code and poked into a data structure called the Device Table. ; Finally, the hardware gets poked to agree with the table by ; calling the BIOS routine responsible for intializing devices. ; ; We'll need to see the CP/M 3 System System Guide to find out ; if this is done right. ; ; ///////////////////////////////////////// ; / / ; / - - W A R N I N G - - / ; / / ; / This code uses CP/M 3 dependent / ; / stuff. / ; / / ; ///////////////////////////////////////// ; ; = = = = = = = = = = = = = = = = = = ; ; Use the "SET" command to change the baudrate when desired. ; ; To use: First edit this file, filling in answers for your own ; equipment.
