1.0	^^SUMMARY\\
.B 1
^THIS IS THE FIRST RELEASE OF THE ^^DC76\\ CODE.
.B 1
^THIS SOFTWARE IS DESIGNED TO SUPPORT ANY STANDARD ^D^C76 CONFIGURATION.
^THE CODE DOES NOT REQUIRE ASSEMBLY-TIME
SPECIFICATION OF CONFIGURATION PARAMETERS SUCH AS NUMBER OF LINES, ETC.
.B1
^D^C76 FEATURES INCLUDE:
.B 1;.LM 8;.TS 8;.I -3
-	^CONTROL OF UP TO 128 FULL-DUPLEX OR FULL-DUPLEX
WITH LOCAL COPY ASYNCHRONOUS LINES. ^THESE MAY BE LOCAL OR DIAL-UP LINES.
.B 1;.I -3
-	^INDIVIDUAL LINE SPEEDS PROGRAM-SELECTABLE FROM 50 TO 9,600 BAUD.
.B 1;.I -3
-	^SPLIT-SPEED (TRANSMIT/RECEIVE) OPERATION PROGRAM-SELECTABLE
ON A PER-LINE BASIS.
.B 1;.I -3
-	^AUTOMATIC BAUD DETECTION FOR 110, 134.5, 150, AND 300-BAUD LINES.
.B 1;.I -3
-	^^ASCII, EBCDIC, APL,\\ OR ^CORRESPONDENCE ^CODES INDEPENDENTLY
SELECTABLE ON EACH LINE.

4.0	^^INSTALLATION INSTRUCTIONS\\
.B 1
^THE ^^DC76\\ PROGRAM IS DISTRIBUTED AS A BINARY FILE (^^DC76.BIN\\).
.B 1
^USE ^^BOOT11\\ TO LOAD THE ^^DC76\\.
^IF THE ^^DC76\\ IS ON ^^DL10\\ PORT 0 USE THE FOLLOWING COMMANDS:
.B 1;.I 10
^^.R BOOT11\\
.I 10
^^/CLEAR/PORT:0\\
.I 10
^^DC76.BIN/PORT:0\\

6.0	^^SPECIAL CONSIDERATIONS\\
.B 2
6.1	^AUTO-^BAUD ^DETECTION
.B 1
^ALL ^^DC76\\ LINES WILL INITIALLY BE DEFINED AS AUTO-BAUD LINES. ^THIS
MEANS THAT THE ^^DC76\\ WILL SCAN INCOMING CHARACTERS UNTIL IT FINDS
WHAT APPEARS TO BE A CARRIAGE RETURN. ^WHEN THE ^^DC76\\ DETERMINES A
LINE SPEED THE MONITOR WILL TYPE OUT:
.B 1;.I 10
^^PLEASE LOGIN OR ATTACH\\
.B 1
^AT THIS POINT ^^SET TTY SPEED\\ COMMANDS MAY BE USED TO REDEFINE THE BAUD RATE.
.B 1
^AT TIMES IT MAY BE DESIRABLE TO INITIALIZE A LINE AT A SPECIFIC BAUD RATE
RATHER THAN AUTO-BAUD. ^THIS MAY BE DONE BY USING THE ^^TTY.INI\\ FILE
AND THE ^^INITIA\\ PROGRAM.
.B 2
6.2	^DATASET ^LINES
.B 1
^ALL DATASET LINES MUST BE DECLARED TO ^^MONGEN\\. ^LINES WHICH ARE NOT
DECLARED WILL ANSWER AND THEN HANG UP 30 SECONDS LATER.
.B 2
6.3	2741 ^LINES
.B 1
^IF THE ^^DC76\\ DETECTS A BAUD RATE OF 134.5, IT WILL DEFINE THE LINE
AS A 2741 LINE WITH DEFAULT ELEMENT TYPE. ^AT THIS POINT A ^^SET TTY ELEMENT\\
COMMAND MAY BE USED TO DEFINE THE ELEMENT BEING USED. ^IF THE ^^PLEASE#LOGIN\\
OR ^^ATTACH\\ MESSAGE IS GARBLED, THE SYSTEM MAY NOT BE ABLE TO RECOGNIZE
THE ^^SET TTY\\ COMMAND. ^TO ELEVIATE THIS PROBLEM TYPE ^^LOGIN\\<CARRIAGE RETURN>.
^THIS WILL GIVE THE SYSTEM ENOUGH INFORMATION TO BE ABLE TO DECODE
^^SET TTY\\ COMMANDS.
