; M7TV-7.ASM -- TeleVideo TS-802/803 overlay file for MDM7xx. 09/08/84
;
; 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 modem port on the TeleVideo TS-802 or the TS-803
; to the modem program.
;
; Edit this file for your preferences then follow the "TO USE:" example
; shown below.
;
; NOTE: If using a TS-803, the SENDRDY equate must be set to
; the value of the same label in the body of MDM7.
;
; Use the "SET" command to change the baudrate when desired. It starts
; out at 300 baud when the program is first called up.
;
; TO USE: First edit this file filling in answers for your own
; equipment. Then assemble with ASM.COM or equivalent
; assembler. Then use DDT to overlay the the results
; of this program to the original .COM file:
;
; A>DDT MDM740.COM
; DDT VERS 2.2
; NEXT PC
; 4A00 0100
; -IM7TV-7.HEX (note the "I" command)
; -R ("R" loads in the .HEX file)
; NEXT PC
; 4A00 0000
; -G0 (return to CP/M)
; A>SAVE 73 MDM740.COM (now have a modified .COM file)
;
; = = = = = = = = = = = = = = = = = =
;
; Or (easier and less error-prone) use MLOAD.COM instead of the above
; DDT.COM merge-technique:
;
; A>MLOAD21 MDM.COM=MDM740.COM,M7TV-7.HEX
;
; = = = = = = = = = = = = = = = = = =
;
; 09/10/84 Reason for the last several - Irv Hoff
; changes were because SENDRDY
; is being used, not RCVREADY,
; this is now fixed correctly
; 09/08/84 Fixed 2nd trivial 803 error - Tim Chiaretto
; 08/15/84 Fixed a trivial 803 error - Irv Hoff
; 08/08/84 Fixed for 802/803 both with - Irv Hoff
; information from M7TVI-3
; 11/11/83 Renamed to M7TV-1.ASM - Irv Hoff
; 07/27/83 Renamed to work with MDM711 - Irv Hoff
; 07/01/83 Revised to work with MDM711 - Irv Hoff
; 06/22/83 Revised to work with MDM711 - Irv Hoff
; 05/27/83 Updated to work with MDM709 - Irv Hoff
; 05/15/83 Revised to work with MDM708 - Irv Hoff
; 04/27/83 Revised to work with TV802 - Irv Hoff
; 02/17/83 Modified MDM703CF for Datapoint
; 1560 computers using an external
; modem - Irv Hoff
