FORMATTING AND MANAGEMENT OF
STANDARD DATA TRANSMISSIONS
1.H
d. STREAM (STR) AND ESCAPE (ESC) COMMANDS
Command: Response (transmission from Computer Interface Port
only, regardless of means of entry,
continuously repeated
until cancelled by ESCAPE (ESC)):
STR [CR] Outputs x, w (, z) [CR][LF] for all scanned channels,
including Nos. 998 (TIME) and 999 (DATE), along with
specified HEADER and/or TAILER
STR x [CR] Outputs x, w (, z) [CR][LF] for Channel No. x only,
along with specified HEADER and/or TAILER
STR x TO y [CR] Outputs x, w (, z) [CR][LF] for all channels from Chan-
nel No. x to and including Channel No. y (y ≥ x), along
with specified HEADER and/or TAILER
To halt a transmission produced in response to any of the above
STREAM (STR)
commands, you must apply the ESCAPE (ESC) command. This you may do by
pressing the keyboard’s
Esc key or by transmitting either the mnemonic ESC or
the ASCII
[Esc] character (= hex 1B) to System 10 via the Computer Interface
Port. When applied, the
ESC command not only terminates any transmission
from the Computer Interface Port currently in progress, but also has the effect of
clearing any partial command that has been entered.
For use of a special “header” or “tailer” string to allow
nonscrolling CRT display of
the datastream output, see Section 1.H.3(c), below.
e. HARD COPY (HCY) COMMAND
Command: Response (transmission from Computer Interface Port
only, regardless of means of entry, one time only):
HCY [CR] Outputs x, w (, z) [CR][LF] for all scanned channels,
including Nos. 998 (TIME) and 999 (DATE), along with
specified HEADER and/or TAILER
HCY x [CR] Outputs x, w (, z) [CR][LF] for Channel No. x only,
along with specified HEADER and/or TAILER
HCY x TO y [CR] Outputs x, w (, z) [CR][LF] for all channels from Chan-
nel No. x to and including Channel No. y (y ≥ x), along
with specified HEADER and/or TAILER
f. LIMIT ZONE (LZN) COMMAND
Command: Response (transmission from Computer Interface Port
or answer appearing on mainframe “billboard” display,
depending on means of command entry):
LZN x [CR] Outputs z [CR][LF] for Channel No. x only; billboard
will display the words
BELOW LIMITS (for z = 1),
BETWEEN LIMITS (for z = 2), or ABOVE LIMITS (for z =
3)
