Custom Terminal Configuration—Custom terminal definition...

enables the same full-screen display characteristics as the ANSI option, but

with a non-ANSI terminal.

If you select the Custom terminal definition... option, you are led

through three screens to specify the control or escape sequences used by the

terminal. On each screen, you must enter the actual control character

sequence, either by typing control characters individually or by pressing the

terminal’s appropriate function key (if it has one). For example, if the

terminal’s sequence to “home” the cursor is ESC-H, you can either press the

ESC key followed by the H key or simply press the “Home Cursor” function

key on the terminal.

Control sequences may contain common character codes such as “backspace”

or “carriage return” that are also used for input editing. Your input,

therefore, for these screens is handled differently. You must ﬁrst enter a

delimiter character (choose any character desired). The control sequence is

then entered—normal editing characters are ignored. Finally, to signal the

end of the sequence, and to terminate input, you must enter the same

delimiter character again.

Obviously the control sequence cannot contain the delimiter character itself—

you must choose a delimiter character that is known not to occur within the

terminal’s escape sequence. Also, the ﬂow control characters XON (^Q) and

XOFF (^S) may not appear within any sequence.

If you conﬁgure a terminal with an Erase Screen capability, the management

agent will not scroll the screen but will instead erase and paint the screen

from the top. This is generally more pleasant than scrolling.

If the terminal has a Home Cursor capability, the management agent will not

erase or scroll the screen to update an existing display, but will instead

“home” the cursor and then display updated information. This feature avoids

the appearance of screen “ﬂicker.”

The Erase End Of Line (EOL) capability provides an efﬁcient method for the

management agent to erase old information when updating an existing

display. If Erase EOL is not conﬁgured, the management agent will use an

appropriate number of space characters to erase old information.
