Using a Display With an AHached Printer
If your terminal has a locally attached printer, the 3708 can send data to both the
display and the pririter.
C2
Functions that Control Data Flow
The 3708 uses the printer only when the display is operating in full-screen mode.
Once your display is operating in full-screen mode, an indication is sent to the host
that the printer is available. At this time, the printer can be used for printing host
data, for p'rinting copies of screens from your display, or for printing copies of
screens from displays on other ports (local copy function).
For most terminal types, the 3708 sends control information to the terminal, which
directs subsequent data to either the display or the printer. The 3708 shares the line,
sending some data for the display and then some for the printer, when data for both
has been received.
In some cases, you may find it inconvenient to have data sent to your printer when
you are trying to perform interactive functions at the display. Four keyboard
functions are available that allow you to control the data flow to your terminal:
Suspend Display
This function prevents data from being sent to the display. 1t
remains in effect until. you enter the Resume Display key
sequence.
Resume Display
This function allows data to be sent to the display.
Suspend Printer
This function prevents data from being sent to the printer. It
remains in effect until you enter the Resume Printer key
sequence.
Resume Printer
Note: If data is being printed when this function is issued, the
printer might not stop immediately.
This function allows data to be sent to the printer.
You can request these functions at any time from the keyboard, even when a
keyboard is locked.
C2
Configuration Note: For the 3708, the port that you access must be configured with DEVICE TYPE
=
4 to allow a
terminal o(this type to be used. The support provided for this function is called Multiple LU.
It
allows your
display and your printer to simultaneously share a single port while maintaining an appearance of two distinct LUs
to an SNA host.
