Configuring the Terminal
Table 2-2. Terminal Configuration Menu Fields (Continued)
~--~--------------~(
PrinterCode4
Device code "4" is ordinarily used only for selecting an external printer. Through the use of this
(Cont'd)
configuration parameter, however, you can redirect the device control operations to the integral
printer without altering the host computer program.
PrinterNull5
LocalEcho
Cap~
Lock
Values:
EXT
(external printer)
INT
(integral printer)
Default:
EXT
This field specifies the number of ASCII null codes (0-255) to be transmitted to an external printer
after each ASCII control code.
Value:
0-255
Default:
0
This field is the functional equivalent of the HALF/FULL DUPLEX toggle switch on an HP 2645
terminal.
ON =
Characters entered through the keyboard are both displayed on the screen and transmitted
to the host computer.
OFF =
Characters entered through the keyboard are transmitted to the host computer only (if they
are to appear on the screen, the host computer must "echo" them back to the terminal).
Default:
OFF
This field is the functional equivalent of the CAPS LOCK latching key on an HP 2645 terminal.
ON =
The terminal generates only Teletype-compatible codes: uppercase ASCII (00-5F, hex) and
DEL (7F, hex). Unshifted alphabetic keys (a-z) generate the codes for their uppercase equiva-
(
lents, the {,
I,
and} keys generate the codes for [, \, and I (respectively). The keys for gen-
erating - and' are disabled.
Start Col
ASCI18B1ts
Xm!tFnctn(A)
2-4
OFF =
The terminal generates the full 128-character ASCII set of codes.
Default:
OFF
If the line in which you are entering data is the bottommost used line in display memory (there are
no printing or non-printing characters following the current line in display memory), the terminal
automatically generates a logical start-of-text pointer to designate the leftmost character that you
enter in the line. This pointer remains with the line in display memory until the line is deleted.
When you are operating in MODIFY LINE or MODIFYALL mode and you press
II
or
II1II,
the data
transmission from the terminal normally begins at the logical start-of-text pointer in the particular
line. If the line has no logical start-of-text pointer, however, the data transmission begins at the
designated start column. This designated start column can be defined and saved in non-volatile
memory using the
Shrteol
field of the terminal configuration menu. The active value of this field
can also be temporarily redefined using one of the
"marg! n!5/tab!5/col"
function keys.
Value:
1-80
Default:
1
When this operating mode is enabled
(-YES),
the terminal transmits 8-bit ASCII codes in which the
eighth (high-order) bit, when set (= 1), indicates that the character is from the alternate character
set. This is a Hewlett-Packard convention and you will ordinarily use it only when communicating
with an HP 300 Computer System or in conjunction with certain HP line printers (such as the HP
2635A/B Printing Terminal).
Values:
YES =
8-bit codes.
NO =
Standard 7-bit codes.
Default:
NO
This field is the functional equivalent of keyboard interface strap A on an HP 2645 terminal.
