CCM Initialization
3 -
Not used.
4 -
0 ETX should not set NDB.
5 -
1 ETX should reset NDB.
6 -
0 Do not inhibit setting of sequence
counter.
8, 7 -
00 Will not affect sequence counter when
Bit 6 is set to
O.
12-9 -
0001 Identical to 2 3 - 2 0 of CRB (vari-
able by program). Generate CM using
these bit settings for CRB which in-
dicate a good message indication upon
receipt of ETX. This must be specified
since this system uses character parity
(CP) only.
13 -
1 Terminate existing command (Read)
upon recognition of ETX from remote
video terminal.
14 -
0 Exclude ETX from BP count.
15 -
0 Do not ignore this character.
16 -
0 OW-2 not required.
17 -
Parity.

1.
Receive/Transmit set to 1 - processor receIvIng NDB set to 0 -
system should be out-of-data block when EOT is received (placed
out of data block by previous ETX). Sequence counter not necessary
when this character is received.
2.
OW-1 and 2 Bit Settings:
2, 1, 0 (Action Control) -
001, unconditional action.
3 -
0 Not Used.
2-12
4 -
0 EOT should not set NDB.
5 -
0 EOT should not reset NDB.
6 -
0 Do not inhibit setting of sequence
counter.
8, 7 -
00 Will not affect sequence counter when
bit 6 is set to
O.
12-9 -
0101 Identical to 2 3 - 2 0 of CRB (vari-
able by program) - any configuration
will suffice in this case. Generate CM
indicating receipt of EOT.
13 -
1 Terminate existing command (Read)
upon recognition of EOT from remote
video terminal. Processor/CCM/Buf-
fer would have been previously placed
