Integral Printer Control
When performing data logging in Remote mode, the terminal and host computer must be
using the ENQ-ACK or XON-XOFF handshakes or they must be using a baud rate that is
equal to or less than the rate at which the slowest selected printer can function. (You will
probably have to drop to 600 baud, if no handshaking is used.)
From the keyboard, you enable and disable data logging using the
LOG TOP
and
LOG BOTTOM
keys. These keys alternately enable and disable top logging and bottom logging, respectively.
When either is enabled, an asterisk appears in the associated key display.
From a program executing in a host computer, you enable and disable data logging using the
following escape sequences:
ENABLE BOTTOM LOGGING:
Ec&p11 C
ENABLE TOP LOGGING:
Ec&p12C
DISABLE LOGGING:
Ec&p13C
Both forms of data logging may not be enabled simultaneously. Once either form of data
logging is enabled, it remains enabled until explicitly disabled, until the other form of data
logging is enabled, until a hard reset is performed, or until the power is turned off.
Note that the keyboard is temporarily locked while a line of data is being CClogged". This may
make it difficult to perform any keyboard operations if a large quantity of data is coming into
the display over the datacomm line rapidly enough to result in continuous logging.
PRINTER OPERATIONS
You can copy, from the display, a selected line, a part (or all) of the displayed page, or a part
(or all) of the active workspace. The cursor is used as the selector to determine the line at
which the copy operation starts. To do so, you must select the printer as the destination CCto")
device. The display is defined as the CCfrom" device in data transfers to the printer.
The operation sequence is to select the printer as a CCto" device, place the cursor in the line at
which you want printing to start, then display the cCdevice control" set of function keys and
select
COpy LINE, COpy PAGE,
or
COpy ALL.
Copy Line
When the integral printer is selected as a destination device, you can copy the line containing
the cursor from the display to the printer. The entire line is copied; block terminators are
ignored. After the line is printed, the cursor moves to the leftmost column in the next lower
line (column 0, not the left margin). If the cursor is on an empty line,
COpy LINE
will not
cause anything to be printed; instead, the paper will be advanced one line.
From the keyboard, you copy one line of data using the
COpy LINE
key in the cCdevice control"
set of function keys.
