Multinational mode
Factory default: Checked
This option will only be available if the system is configured for a language that supports national
replacement character sets.
The setting of this option determines the type of character set used to generate characters. When
unchecked, TeemTalk is in National mode in which a character set specific to the selected
keyboard nationality is used. When checked (default) TeemTalk is in Multinational mode in which
a character set consisting of two tables of characters is used. This enables characters from any
keyboard nationality to be generated.
●
Lines per screen
Factory default: 24
This specifies the number of text rows that can be viewed in the workspace at any one time out of
the total number stored in memory. This can be set to a maximum of 64. Note that the number of
rows stored in memory is specified by the Buffer lines option.
●
Buffer lines
Factory default: 144
This option determines the number of text rows that are stored in memory. This can be set from 0
to 528 rows by default. The Display Rows option specifies the number of memory rows that can
be viewed in the workspace at any one time.
●
Lines per page
Factory default: 24
When TeemTalk is in VT420 mode, the display memory of 144 lines can be divided into several
pages, up to a maximum of six pages of 24 lines each. The setting of this option determines the
number of lines on a page and therefore how many pages are available. Note that the page size
can be larger than the Lines per screen setting, in which case you can scroll the page up or
down in the window by holding down the Ctrl key and pressing the Up or Down Cursor keys.
When TeemTalk is in any mode other than VT420, the page size is the same as the Lines per
screen setting.
●
Columns per screen
Factory default: 80
This option enables you to specify a width of 80 or 132 columns for the workspace. When set to
132, the setting of the Use 80 Column Font option determines whether all 132 columns are
displayed using a narrow font, or only 80 columns at a time using the normal (80 column) font,
with the ability to scroll horizontally to view the remaining columns.
●
Columns per page
Factory default: 80
This option specifies the width of display memory for DEC VT modes, in the range 80 to 132
columns. When the number of Columns per screen is less than the page width specified here,
you can scroll horizontally to view the hidden columns by holding down the Ctrl key and pressing
the Left or Right Cursor keys.
