Configuring the Terminal
Table 2-2. Terminal Configuration Menu Fields (Continued)
YES
=
The escape code sequences generated by control keys such as
1/1
and
II
are trans-
mitted to the host computer. If local echo is ON, the function is also performed locally.
NO
=
The escape code sequences for the major function keys are executed locally but NOT
transmitted to the host computer.
Default:
NO
This field is the functional equivalent of keyboard interface strap B on an HP 2645 terminal.
NO
=
Spaces entered through the keyboard will overwrite existing characters.
YES
=
Enable SPace OverWrite (SPOW) latch. When the SPOW latch is off, overwriting occurs as
normal. When the SPOW latch is on, spaces entered through the keyboard move the cursor
forward but do not overwrite existing characters. The SPOW latch is turned on by a carriage
return and is turned off by a line feed, home up, or tab. It may also be turned on and off pro-
grammatically through the use of an
<ESC>&k
sequence as follows:
ON:
<ESC>&k 1N
OFF:
<ESC>&k ON
Default:
NO
This field is the functional equivalent of keyboard interface strap C on an HP 2645 terminal.
NO
=
When the cursor reaches the right margin, it automatically moves to the left margin in the next
lower line (a local carriage return and line feed are generated).
YES
=
When the cursor reaches the right margin, it remains in that screen column until an explicit
carriage return or other cursor movement function is performed (succeeding characters
overwrite the existing character in that screen column).
Default:
NO
This field is the functional equivalent of keyboard interface strap D on an HP 2645.
LINE
=
When operating in block mode, the terminal will transmit data a line at a time (or a field at a
time if format mode is enabled).
PAGE
=
When operating in block mode, the terminal will transmit data a page at a time.
For a detailed description of the differences between block line and block page mode refer to "The
ENTER Key" in section IV of this manual.
Default: LINE
These fields are the functional equivalents of keyboard interface straps G and H on an HP 2645
terminal. Together they determine what type of handshaking is to be used when transferring blocks
of data from the terminal to the host computer.
The various types of block transfers that may occur are as follows:
• A data transfer initiated by pressing the
am
key in character, block line, or block page mode.
• A data transfer initiated by pressing the
am
or _
key in modify mode.
• A data transfer initiated by pressing a transmit only
(T)
user key
("-B).
• The terminal's response to a cursor sense, terminallD status, primary status, secondary status,
or device status request issued from the host computer.
• The device control completion code (S, F, or U) transmitted by the terminal in conjunction with a
device control operation initiated by the host computer.
When performing block transfers, there are three possible handshakes:
1. No handshake; terminal merely transmits block of data.
