data stream
PURPOSE
Defines the data stream that an HFT virtual terminal uses in KSR mode.
DESCRIPTION
AIX is capable of addressing 1024 distinct displayable characters. To
designate these characters using 8-bit bytes, a code page convention is used.
Each code page is an ordered set of up to 256 characters, which are called code
points. The first 32 code points of each code page are reserved for control
codes and are the same for all code pages. The control codes do not have
graphic representations, so each code page can have a maximum of 224 distinct
graphic characters.
The remaining characters are included in a code page called P0. Two additional
code pages called USER1 and USER2 are provided for user-defined symbols.
Code points in the range 32 to 127 (0x20 to 0x7F) of code page P0 represent the
standard 7-bit US ASCII graphic symbols. P0 code points 128 to 255 (0x80 to
0xFF).
The following code page map shows the predefined graphic display symbols and
their code point values in code page P0.
Hardware limitation
You will not be able to display all the symbols described in this section on
the VGA adapter if you have changed from the standard software character mode
to the optional hardware character mode. This can be done with either the
display command or with a change font order to the hft device driver.

NONSPACING CHARACTERS
For convenience when typing diacritical (accented) characters, a nonspacing or
"dead" character facility is provided. A nonspacing character sequence is a
two-key sequence consisting of one of the 13 diacritics followed by an
alphabetic character or a space. The virtual terminal subsystem converts this
two-key sequence into a single code point that may have a single-shift prefix.
The resulting character is the alphabetic character with the specified
Processed November 7, 1990 DATA STREAM(7,F) 1
DATA STREAM(7,F) AIX Technical Reference DATA STREAM(7,F)
diacritic mark. A diacritic followed by a space translates to the diacritic
character itself. The 13 valid diacritics are:
Acute Accent or Apostrophe 0xEF or 0x27
` Grave Accent 0x60
^ Circumflex Accent 0x5E
Umlaut Accent 0xF9
~ Tilde Accent 0x7E
Caron Accent 0x1FF3
Breve Accent 0x1E9D
" Double Acute Accent 0x1E9E
Overcircle Accent 0x1FFD
Overdot Accent 0x1E85
Macron Accent 0x1EA3
Cedilla Accent 0xF7
Ogonek Accent 0x1E87
If a nonspacing character and the following character do not combine to form a
diacritical character in the set of predefined graphic symbols, then the
diacritic is treated as a separate character code. For example, "~Q" is
treated as two characters, "~" and "Q".
Note that nonspacing characters apply only to keyboard input and are not a
feature of the data stream used by applications. Also, a diacritic must be
explicitly designated as being nonspacing in the keyboard mapping for this
facility to operate. None of the keys on the standard U.S. keyboard mapping
are defined to be nonspacing characters. However, nonspacing characters can be
defined. See "Set Keyboard Map (HFSKBD)" for details.
CONTROLS
Two types of controls are valid in a character stream data:
o Single-byte controls (also called control characters and control codes),
which have character values from 0 to 31 (0x00 to 0x1F)
o Multi-byte controls, which are also called escape sequences and control
sequences.
Single-Byte Controls
The following list shows the single-byte controls and their interpretation in
KSR coded data. A line introducing each control gives its mnemonic, its code
value, and its function.
o NUL, 0x00, (Null) has no terminal function.
o SOH, 0x01, (Start of Header) has no terminal function.
o STX, 0x02, (Start of Text) has no terminal function.
o ETX, 0x03, (End of Text) has no terminal function.
Processed November 7, 1990 DATA STREAM(7,F) 2
DATA STREAM(7,F) AIX Technical Reference DATA STREAM(7,F)
o EOT, 0x04, (End of Transmission) has no terminal function.
o ENQ, 0x05, (Enquiry) has no terminal function.
o ACK, 0x06, (Acknowledge) has no terminal function.
o BEL, 0x07, (Bell) causes an audible alarm to sound.
o BS, 0x08, (Backspace) moves the cursor position to the left one column,
unless the cursor is at the left boundary of the presentation space. In
that case, the cursor position does not change.
o HT, 0x09, (Horizontal Tab) moves the cursor position forward to the next
tab stop. If the cursor is already in the last column of a line, then the
cursor position does not change. Note that the CHT (cursor horizontal tab)
multibyte control performs a similar operation, but also performs line
wrapping.
o LF, 0x0A, (Line Feed) if the LNM mode is reset, the line feed moves the
cursor position down one line. If the LNM mode is set (default), the line
feed is treated as a NEL and moves the cursor position to the first
position of the next line. In either case, if the cursor is already on the
last line of the PS, the PS lines scroll up one line. The top line of the
PS disappears and a blank line is inserted as the new bottom line.
o VT, 0x0B, (Vertical Tab) moves the cursor position down to the next line
that is defined as a vertical tab stop. Tabs stops are always set at the
first and last lines of the PS. If the cursor was already on the last line
of the PS and HFWRAP mode is not set, the cursor stays on the last line in
the PS. If HFWRAP mode is set, the cursor moves to the top line in the PS.
The column position does not change in any case.
o FF, 0x0C, (Form Feed) treated as a line end.
o CR, 0x0D, (Carriage Return) if the CNM mode is reset (default), the
carriage return moves the cursor position to the first character of the
line indicated by the cursor. If the CNM mode is set, the carriage return
is treated as an NEL and causes the cursor position to move to the first
position of the next line. In this case, if the cursor is already on the
last line of the PS, the PS lines scroll up one line. The top line of the
PS disappears and a blank line is inserted as the new bottom line.
o SO, 0x0E, (Shift Out) maps the subsequently received graphic codes to
display symbols according to the active G1 character set. See "display
symbols" for a list of the display symbols.
o SI, 0x0F, (Shift In) maps the subsequently received graphic codes to
display symbols according to the active G0 character set. See "display
symbols" for a list of the display symbols.
o DLE, 0x10, (Data Link Escape) has no terminal function.

o DC4, 0x14, (Device Control 4) has no terminal function.
o NAK, 0x15, (Negative Acknowledgment) has no terminal function.
o SYN, 0x16, (Synchronous) has no terminal function.
o ETB, 0x17, (End of Block) has no terminal function.
o CAN, 0x18, (Cancel) has no terminal function.
o EM, 0x19, (End of Medium) has no terminal function.
o SUB, 0x1A, (Substitute) has no terminal function.
o ESC, 0x1B, (Escape) defines the beginning of a multibyte control sequence
as defined in "Multi-Byte Controls."
o DEL, 0x7F, (Delete) has no terminal function.
Multi-Byte Controls
This section defines the code points and effects on the virtual terminal for
multibyte control sequences that are recognized in KSR mode. All of them begin
with the ESC code (0x1B) followed by a "[" (0x5B) and include all subsequent
bytes up to and including the first code in the range 0x40-0x7F. Any multibyte
control sequences not defined below are ignored. Invalid sequences return an
error Device Status Report to the program. Multi-byte control sequences of
more than 16 codes are considered invalid on receipt of the 17th code. The
next code is not considered a part of that sequence. Also, numeric parameters
in control sequences contain no more than 3 digits. The numeric value of the
parameter may be incorrect if more than three digits are used, and the numeric
value never exceeds 255.
Controls effect a virtual terminal's presentation space (PS) and its related
cursor (pointer into the PS). The presentation space is a logical array of
display symbols, N columns by M lines.
The following list gives the valid multibyte control code sequences. A line
introducing each control gives its mnemonic, its code sequence, and its
function. The code sequence is shown in terms of ASCII characters. For
example, the sequence ESC A represents two codes with a value of 0x1B41.
o CBT ESC [ PN Z Cursor Back Tab
Processed November 7, 1990 DATA STREAM(7,F) 4
DATA STREAM(7,F) AIX Technical Reference DATA STREAM(7,F)
Moves the cursor back the number of horizontal tab stops specified by PN.
Tab stops are always set at the first and last columns of each line. If
the cursor is already in the first column of a line and HFWRAP mode is set,
the cursor moves to the last column. If AUTONL is also set, the cursor
moves to the last column of the previous line. In this case, if the cursor
is already on the first row of the PS, it moves to the last row.
o CHA ESC [ PN G Cursor Horizontal Absolute
Moves the cursor to the column specified by PN, unless the column exceeds
the PS width. If the column exceeds the PS width, the cursor moves to the
PS column farthest to the right.
o CHT ESC [ PN I Cursor Horizontal Tab
Moves the cursor position forward to the PN(th) following tab stop. If the
cursor is already in the last column of a line and HFWRAP mode is set, then
the cursor returns to the first column of the line. If AUTONL mode is also
set, then the cursor moves to the first column of the next line. In this
case, if the cursor is already on the last line of the PS, then the cursor
moves to the first column of the first line. Note that the HT (horizontal
tab) single-byte control does not cause wrapping to occur.
o CTC ESC [ PS W Cursor Tab Stop Control
0 Set a horizontal tab at cursor.
1 Set a vertical tab at cursor.
2 Clear a horizontal tab at cursor.
3 Clear a vertical tab at cursor.
4 Clear all horizontal tabs on line.
5 Clear all horizontal tabs.
6 Clear all vertical tabs.
Sets or clears one or more tabulation stops according to the parameter
specified. Tab stops on the first or last column cannot be cleared. When
horizontal tab stops are set or cleared, the number of lines affected is
all (if Tabulation Stop Mode is set) or one (if Tabulation Stop Mode is
reset). This control does not change the position of characters already in
the presentation space.
o CNL ESC [ PN E Cursor Next Line
Moves the cursor down the number of lines specified by PN, and over to the
first position of that line. If the cursor was already on the bottom PS
line and HFWRAP mode is not set, it is positioned at the beginning of that
line. If HFWRAP mode is set, the cursor wraps from the bottom line to the
top PS line.
o CPL ESC [ PN F Cursor Preceding Line
Moves the cursor back the number of lines specified by PN, and over to the
first position of that line. If the cursor was already on the top PS line
Processed November 7, 1990 DATA STREAM(7,F) 5
DATA STREAM(7,F) AIX Technical Reference DATA STREAM(7,F)
and HFWRAP mode is not set, the cursor is positioned at the beginning of
that line. If HFWRAP mode is set, the cursor wraps from the top line to
the bottom line of the PS.
o CPR ESC [ PN ; PN R Cursor Position Report
This is the report that is returned when you issue the Device Status Report
Request (see DSR control). The first numeric parameter is the line number,
and the second is the column. Line and column values are sent to the
application as information. You do not normally send this report to the
virtual terminal, but if you do, it is treated as a CUP control.
o CUB ESC [ PN D Cursor Backward
Moves the cursor backward on the line the specified number of columns. If
this cursor movement exceeds the left PS boundary and HFWRAP mode is not
set, the cursor stops at the leftmost PS position. If HFWRAP mode is set,
the cursor wraps from the leftmost column to the rightmost column of the
preceding PS line. In HFWRAP mode the cursor also wraps from the home to
the rightmost bottom position of the PS.
o CUD ESC [ PN B Cursor Down
Moves the cursor down the number of lines specified by PN. If this cursor
movement exceeds the bottom PS boundary and HFWRAP mode is not set, the
cursor stops on the last PS line. If HFWRAP mode is set, the cursor wraps
from the bottom line to the top line of the PS.
o CUF ESC [ PN C Cursor Forward
Moves the cursor forward on the line the specified number of columns. If
this cursor movement exceeds the right PS boundary and HFWRAP mode is not
set, the cursor stops at the rightmost PS position. If HFWRAP mode is set,
the cursor wraps from the rightmost column to the leftmost column of the
following line in the PS. In HFWRAP mode, the cursor also wraps from
rightmost bottom position to the home position of the PS.
o CUP ESC [ PN ; PN H Cursor Position
Moves the cursor to the line specified by the first parameter, and to the
column specified by the second parameter. If this movement crosses a PS
boundary, the cursor stops at the PS boundary.
o CUU ESC [ PN A Cursor up
Moves the cursor up the specified number of lines. If this cursor movement
exceeds the top PS boundary and HFWRAP mode is not set, the cursor stops on
the first PS line. If HFWRAP mode is set, the cursor wraps from the top
line to the bottom line in the PS.
o CVT ESC [ PN Y Cursor Vertical Tab
Processed November 7, 1990 DATA STREAM(7,F) 6
DATA STREAM(7,F) AIX Technical Reference DATA STREAM(7,F)
Moves the cursor down the number of vertical tab stops specified. Tab
stops are assumed at the top and bottom PS lines. If there are not enough
vertical tab stops in the PS and HFWRAP mode is not set, the cursor stops
on the last line in the PS. If HFWRAP mode is set, the cursor wraps from
the bottom line to the top line of the PS.
o DCH ESC [ PN P Delete Character
Deletes the cursor character and the following PN-1 characters on the line
indicated by the cursor. The characters following the deleted characters
on the line overlay the deleted character positions. The line is cleared
from the end of the line to the edge of the presentation space. If the
number of characters to be deleted exceeds the number of columns from the
cursor to the PS right boundary, then all the characters from the cursor to
the PS boundary are replaced with empty spaces and a DSR control sequence
identifying an error is returned to the application.
o DL ESC [ PN M Delete Line
Deletes the line and the PN-1 following lines in the PS. The lines
following the deleted lines are scrolled up PN lines and PN blanks lines
are placed at the bottom of the PS. If there are less than PN lines from
the line indicated by the cursor to the bottom of the PS, the line
indicated by the cursor and all the following PS lines are replaced with
empty lines.
o DSR ESC [ PN n Device Status Report Request
6 Request Cursor Position Report
13 Error Report
A request cursor position report (CPR) sends a cursor position report from
the virtual terminal to the application. An error report is sent from the
virtual terminal to the application when the virtual terminal receives an
invalid control sequence. Error reports are private reports which conform
to the ANSI standard for private parameters.
o DMI ESC ' (left quote) Disable Manual Input
This control, when received in an output data stream, causes keyboard input
to this terminal to be ignored. This control is ignored when received from
the keyboard.
o EMI ESC b Enable Manual Input
This control, when received in an output data stream, restarts keyboard
input recognition and buffering if previously disabled with a DMI multibyte
control. This control is ignored when received from the keyboard.
o EA ESC [ 0 O Erase to End of Area

DATA STREAM(7,F) AIX Technical Reference DATA STREAM(7,F)
ESC [ 1 O Erase from Start of Area
ESC [ 2 O Erase All of Area.
This control is treated like an EL control sequence.
o ED ESC [ 0 J Erase to End of Display
ESC [ 1 J Erase from Start of Display
ESC [ 2 J Erase All of Display.
Erases certain characters within the PS. Erased characters are replaced
with empty spaces. Erase to end of display erases the character indicated
by the cursor and all following characters in the PS. Erase from start of
display erases the first character of first line and the following
characters up to and including the character indicated by the cursor.
Erase all of display erases all the characters on the PS.
o EF ESC [ 0 N Erase to End of Field
ESC [ 1 N Erase from Start of Field
ESC [ 2 N Erase All of Field.
Erases certain characters between horizontal tab stops. Erased characters
are replaced with empty spaces. Erase to end of field erases the character
indicated by the cursor and all following characters before the next tab
stop. Erase from start of field erases the character at the tab stop
preceding the cursor an the following characters up to and including the
character indicated by the cursor. Erase all of field erases the character
at the tab stop preceding the cursor, and the following characters up to
and including the character at the tab stop following the cursor. Tab
stops are assumed at the first and last columns of the PS when executing
this control.
o EL ESC [ 0 K Erase to End of Line
ESC [ 1 K Erase from Start of Line
ESC [ 2 K Erase All of Line.
Erases certain characters within a line. Erased characters are replaced
with empty spaces. Erase to end of line erases the character indicated by
the cursor and all following characters on the line. Erase from start of
line erases the first character of first line and the following characters
up to and including the character indicated by the cursor. Erase all of
line erases all the characters on the line.
o ECH ESC [ PN X Erase Character
Processed November 7, 1990 DATA STREAM(7,F) 8
DATA STREAM(7,F) AIX Technical Reference DATA STREAM(7,F)
Erases the character indicated by the cursor and the following PN-1
characters on that line. Erased characters are replaced with empty spaces.
If there are less than PN characters from the cursor to the PS right
boundary, then the character indicated by the cursor and all the following
characters on the line are replaced empty spaces.
o HTS ESC H Horizontal Tab Stop
Sets a horizontal tab stop at the current horizontal position. If TSM is
set, then the tab stop applies only to this line. If TSM is reset, then
the tab stop applies to all PS lines. This control does not change the
positioning of characters already in the presentation space.
o HVP ESC [ PN ; PN f Horizontal and Vertical Position
Moves the cursor to the line specified by the first parameter, and to the
column specified by the second parameter. If this movement would cross a
PS boundary, the cursor stops at the current PS boundary.
o ICH ESC [ PN @ Insert Character
Inserts PN empty spaces before the character indicated by the cursor. The
string of characters starting with the character indicated by the cursor
and ending with last character of the line are shifted PN columns to the
right. Characters shifted past the PS right boundary are lost. The cursor
does not move.
o IL ESC [ PN L Insert Line
Inserts PN empty lines before the line indicated by the cursor. The line
indicated by the cursor is scrolled down. The cursor position on the
screen is not affected.
o IND ESC D Index
Moves cursor down one line. If the cursor was already on the bottom line
of the PS, then the top line is lost, the other lines move up one line, and
a blank line becomes the new bottom line.
o NEL ESC E Next Line
Moves the cursor to the first position of the following line. If the
cursor was already on the bottom line of the PS, then the top line is lost,
the other lines move up one, and a blank line becomes the new bottom line.
o KSI ESC [ PS p Keyboard Status Information
The virtual terminal generates this control whenever HFHOSTS and HFXLATKBD
are set and the status of the keyboard changes. Each selective parameter
is the character-coded decimal value of a keyboard status byte. For
example, if the keyboard has two status bytes, the control sequence is ESC
[ xxx;yyy p, where xxx is the value of the high-order byte and yyy is the
Processed November 7, 1990 DATA STREAM(7,F) 9
DATA STREAM(7,F) AIX Technical Reference DATA STREAM(7,F)
value of the low-order byte. This is a private control that conforms to
the ANSI standards for private control sequences. The virtual terminal
display handler ignores this sequence whether it is received from the
application or echoed.
o PFK ESC [ PN q PF Key Report
The control sequence is sent by the virtual terminal to the application
when a program function key (PFK) code is received from the keyboard. The
parameter PN is a PF key number from 1 to 255. This is a private control
that conforms to the ANSI standards for private control sequences. This
sequence is ignored by the virtual terminal display handler whether
received from the application or echoed.
o RCP ESC [ u Restore Cursor Position
Moves the cursor to the position saved by the last SCP control. If no SCP
has been received, then the cursor position is set to the first character
of the first line. This is a private control that conforms to the ANSI
standards for private controls. This control has no terminal function when
received from the keyboard.
o RI ESC L Reverse Index
Moves the cursor up one line, unless the cursor is already on the PS top
line. In that case, if HFWRAP mode is not set, then the cursor does not
move. If HFWRAP mode is set, the cursor moves to the bottom line of the
PS. The column position does not change.
o RIS ESC c Reset to Initial State
Resets the virtual terminal to the state of a newly-opened virtual
terminal: erases all PS data, places the cursor at the home position,
resets graphic rendition to normal, resets subscripting and superscripting,
and sets tab stops, modes, keyboard map, character maps and echo maps to
their default values.
o RM ESC [ PS l Reset Mode
20 LNM - Line Feed - New Line Mode
4 IRM - Insert Mode
12 SRM - Send Receive Mode (set ECHO off)
18 TSM - Tabulation Stop Mode
?21 CNM - Carriage Return - New Line Mode

DATA STREAM(7,F) AIX Technical Reference DATA STREAM(7,F)
TSM mode determines whether horizontal tabs apply identically to all line
(TSM reset) or uniquely to each line on which they are set (TSM set).
o SCP ESC [ s Save Cursor Position
Saves the current cursor position. Any previously saved cursor position is
lost. The cursor can be restored to this position with an RCP control.
This is a private control that conforms to the ANSI standards for private
controls. This control has no terminal function when received from the
keyboard.
o SD ESC [ PN T Scroll Down
Moves all the PS lines down PN lines. The bottom PN lines are lost, and
PN empty lines are put at the top of the presentation space. Physical
cursor position does not change due to the scroll.
o SL ESC [ PN SP @ Scroll Left
Moves all the PS characters PN column positions to the left. The
characters in the PN leftmost PS columns are lost, and empty spaces are put
in the rightmost PN columns of all lines. Physical cursor position does
not change due to the scroll.
o SR ESC [ PN SP A Scroll Right
Moves all the PS characters PN column positions to the right. The
characters in the PN rightmost PS columns are lost, and empty spaces are
put in the leftmost PN columns of all lines. Physical cursor position does
not change due to the scroll.
o SU ESC [ PN S Scroll Up
Moves all the PS lines up PN lines. The top PN lines are lost, and PN
empty lines are put at the bottom of the presentation space. The physical
cursor position does not change due to the scroll.

Causes the next characters received in the data stream or from the keyboard
to have the display attributes specified by the parameter string. Any
parameter not listed above is ignored.
The attributes corresponding to parameters 1 through 9 are cumulative. For
example, specifying underscore and then specifying blink causes following
characters to be underscored and blink. To reset one of these attributes,
specify normal and then reinstate the desired parameters. Multiple
parameters are processed in the order listed.
Whether the characters really have the requested attributes on the display
depends on the capabilities of the physical display device used by the
virtual terminal. The VGA adapter of the PS/2 does not implement all of
the defined capabilities. See "Change Fonts" in the hft section of this
manual for more information on this topic.
