; TCS
; M7TV-9.ASM -- Routines straightened up to comfigure it more like
; the standard modem 740 programs. The set up routine was
; removed from the start up routine. The default baud rate is
; 1200 Baud the printer is available. The clears screen in
; the initial signon routine was removed. This version is
; mainly configured for the TPC-1 but It will support the other
; 802 and 803's
;
; M7TV-8.ASM -- TeleVideo TPC-I added. 07/08/85
; Also disabled the printer due to excessive delay JJW
; when none is connected. This was accopmlished by
; adding 2 commands to SET.
; PRINTON enables the print capability.
; PRINTOFF disables the print capability.
; Note that you must still use ^P to actually enable
; or disable printing.
;
; M7TV-7.ASM -- TeleVideo TS-802/803/803H overlay file for MDM7xx. 10/23/84
;
; 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, TS-803 BIOS
; Versions 1.3 and 1.5, the TS-803H, and the TPC-I to the modem program.
;
; The TPC-I is essentially the same as the TS803.
;
; Edit this file for your preferences then follow the "TO USE:" example
; shown below.
;
; NOTE: If using a TS-803 or TS-803H, the SNDREADY 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 1200 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 MDM7xx.COM
; DDT VERS 2.2
; NEXT PC
; 4A00 0100
; -IM7TV-8.HEX (note the "I" command)
; -R ("R" loads in the .HEX file)
; NEXT PC
; 4A00 0000
; -G0 (return to CP/M)
; A>SAVE 73 MDM7xx.COM (now have a modified .COM file)

; 07/08/85 Added info on the TPC-I. - John Warkentin
; 10/23/84 Added 803 INIT routines for
; BIOS version 1.3 and 1.5
; and 803H - Tim Chiaretto/Ernie Graves
; 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
; information from M7TVI-3 - Irv Hoff
; 11/11/83 Renamed to M7TV-1.ASM - Irv Hoff
; 07/27/83 Renamed to work with MDM711 - Irv Hoff
