IBM 3708 Description page 173

2/4 Color Toggle:
The 3708 supports a 2/4 color toggle for ASCII displays that
support color modes if the terminal table defines both highlighting and color
sequences. The highlighting sequences are used in 2-color mode, and the color
sequences are used in 4-color mode.
At initialization, a terminal that has both highlighting and color sequences defined in
the terminal table, defaults to four-color mode. When the toggle function is
activated, the 3708 switches between modes and repaints the terminal's screen. If the
table does not define both highlighting and color sequences, this function has no
effect.
Refresh:
The Refresh function causes the 3708 to clear your display screen and
send image again. This is most useful when you are using a dial-in facility, and
parity errors cause incorrect characters to appear on the screen.
Terminal Logon Initialization (TLlS) Refresh:
Many terminals require that the 3708
transmit command sequences at the beginning of a session to put the terminal into
the proper mode of operation (see "Special Processing Provided for Specific
Terminal Types" on page 4-72). The 3708 can also be configured to send a
user-defined initialization sequence to the terminal. The TLIS Refresh function
allows the terminal user to, at any time during the session, cause the 3708 to
transmit any defined initialization sequence to the terminal. This function is most
often used to ensure that the terminal is in the proper mode for operation with the
3708.
Resume Display, Resume Printer, Suspend Display, Suspend Printer:
These
functions enable you to control whether the 3708 sends data to the display or to a
printer attached to the auxiliary port of your terminal. If the interaction with your
display is interrupted too often by data being sent to the printer, you can invoke the
Suspend Printer function. This stops traffic to the printer until you use Resume
Printer. Similarly, you can speed up printer traffic by using the Suspend Display
function.
The only functions that you can use while the display is suspended are: Resume
Display, Suspend Printer, and Resume Printer.
Once you have used the Suspend Display function, you must enter the Resume
Display key sequence to use your display.
These functions are not available for terminal which do not have an auxiliary port.
See "Displays with Printers" on page 4-89 for information about using the auxiliary
port printer function.
Terminal Controlled Print Functions:
You may be able to use special print keys on
your terminal to print screen information on a printer attached to your terminal.
For example, with the IBM 3101, the key labeled Print Line can be used to print one
line of the display image. You should see your system administrator to find out if
such keys on your terminal can be used.
