; 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$MODDATP modified to output 00H then 10H per page 75
; of the MicroMate User's Guide (instead of only 10H)
; Bill Wells, University of California, Berkeley CA.
; 10/31/83 BSD Unix communication defaults set by Bill Wells, UCB
; Bill Wells, University of California, Berkeley CA.
; XOFFTST = YES (Unix ports use XON/XOFF)
; CRCDFLT = NO (umodem & tmodem do not have CRC)
; IGNORCTL = NO (so vi, more, & tset work)
; 10/09/83 Modified for MDM712 by Jim Warner, UCSC
; BAUDMATCH routine changed to query user about setting of
; the IGNORCTL. SET$BAUDRATE, AACCOR, and YES$CNTRL added.
; 10/02/83 Modified for MDM712 by Greg Small and Bill Wells,
; University of California, Berkeley CA.
; 07/02/83 Patches (MDM709PM.ASM) for MDM709
; SETLPR, BAUDMATCH, MSPEED$INIT, BIOSPB, BIOSPB1 added.
; Jim Warner - University of California, Santa Cruz.

; Notes by Jim Warner:
;
; The baud rate stuff in this adaptation is a little strange.
; The initial BAUD rate is whatever it was when the program was
; entered. 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.

;
; To use: First edit this file, filling in answers for your own
; equipment. Then assemble with MAC.COM or equivalent
; assembler. Use SID to overlay the results of this
; program on the original .COM file:
;
; A>save (this is for CP/M 3)

; NEXT MSZE PC END
; 040B 4580 0100 D9FF
; #G0 (return to CP/M)
;
; CP/M 3 SAVE - Version 3.0
; Enter file (type RETURN to exit): mdm7p1.com
; Beginning hex address: 0100
; Ending hex address: 457F (MSZE - 1)
