Designates target as the source and destination of I/O ostensibly directed to the device denoted by fd.

Returns 1 if target names the device currently acting as proxy for the device denoted by fd, and 0 if it is not.

Spaces are included only for readability; these characters must occur in the given sequence without the intervening spaces.

Initial setting of the mode for functions that set a mode. To restore the initial settings, use the SUNRESET escape sequence.

Used for consoles that are not equipped with an audible bell. Current Sun workstation models also flash the screen if the keyboard is not the console input device.

The cursor moves one position to the left on the current line. If it is already at the left edge of the screen, no change takes place.

The cursor moves right on the current line to the next tab stop. The tab stops are fixed at every multiple of eight columns. If the cursor is already at the right edge of the screen, nothing change takes place. Otherwise, the cursor moves right a minimum of one and a maximum of eight character positions.

The cursor, while remaining at the same character position on the line, moves down one line. If the cursor is at the bottom line, the screen either scrolls up or wraps around depending on the setting of an internal variable n (initially 1) . The internal variable can be changed using the ESC[r control sequence. If n is greater than zero, the entire screen (including the cursor) is scrolled up by n lines before executing the line-feed. The top n lines scroll off the screen and are lost. New blank lines n scroll onto the bottom of the screen. After scrolling, move the cursor down one line to execute the line feed. If n is zero, wrap-around mode is entered. The ESC [ 1 r exits back to scroll mode. If a line-feed occurs on the bottom line in wrap mode, the cursor goes to the same character position in the top line of the screen. During line-feeds, the line that the cursor moves to is cleared and no scrolling occurs. Wrap-around mode is not implemented in the window system. On SPARC based systems, the speed at which the screen scrolls is dependent on the amount of data waiting to be printed. Whenever a scroll occurs and the console is in normal scroll mode (ESC [ 1 r), it scans the rest of the data awaiting printing to see how many line-feeds occur in it. This scan stops when the console finds a control character from the set {VT, FF, SO, SI, DLE, DC1, DC2, DC3, DC4, NAK, SYN, ETB, CAN, EM, SUB, ESC, FS, GS, RS, US} . At that point, the screen is scrolled by n lines (n \(>= 1) and processing continues. The scanned text is processed normally and fills in the newly created lines. As long as escape codes or other control characters are not intermixed with the text, this results in faster scrolling

With kernel terminal emulator (while remaining at the same character position on the line), the cursor moves down one line. However, with PROM based emulator (while remaining at the same character position on the line), the cursor moves up one line. If the cursor is already at the top line, no change takes place.

The cursor is positioned to the home position (upper-left corner) and the entire screen is cleared.

The cursor moves to the leftmost character position on the current line.

The escape character. Escape initiates a multi-character control sequence.

Takes one parameter, n (default 1). Inserts n spaces at the current cursor position. The current line, starting at the current cursor position inclusive, is shifted to the right by n character positions to make room for the spaces. The rightmost n character positions shift off the line and are lost. The position of the cursor is unchanged.

Takes one parameter, n (default 1). Moves the cursor up n lines. If the cursor is fewer than n lines from the top of the screen, moves the cursor to the topmost line on the screen. The character position of the cursor on the line is unchanged.

Takes one parameter, (default 1). Moves the cursor down n lines. If the cursor is fewer than n lines from the bottom of the screen, move the cursor to the last line on the screen. The character position of the cursor on the line is unchanged.

Takes one parameter, n (default 1). Moves the cursor to the right by n character positions on the current line. If the cursor is fewer than n positions from the right edge of the screen, moves the cursor to the rightmost position on the current line.

Takes one parameter, n (default 1). Moves the cursor to the left by n character positions on the current line. If the cursor is fewer than n positions from the left edge of the screen, moves the cursor to the leftmost position on the current line.

Takes one parameter, n (default 1). Positions the cursor at the leftmost character position on the n-th line below the current line. If the current line is less than n lines from the bottom of the screen, positions the cursor at the leftmost character position on the bottom line.

or

Takes two parameters, n1 and n2 (default 1, 1). Moves the cursor to the n2-th character position on the n1-th line. Character positions are numbered from 1 at the left edge of the screen; line positions are numbered from 1 at the top of the screen. Hence, if both parameters are omitted, the default action moves the cursor to the home position (upper left corner). If only one parameter is supplied, the cursor moves to column 1 of the specified line.

Takes no parameters. Erases from the current cursor position inclusive to the end of the screen, that is, to the end of the current line and all lines below the current line. The cursor position is unchanged.

Takes no parameters. Erases from the current cursor position inclusive to the end of the current line. The cursor position is unchanged.

Takes one parameter, n (default 1). Makes room for n new lines starting at the current line by scrolling down by n lines the portion of the screen from the current line inclusive to the bottom. The n new lines at the cursor are filled with spaces; the bottom n lines shift off the bottom of the screen and are lost. The position of the cursor on the screen is unchanged.

Takes one parameter, n (default 1). Deletes n lines beginning with the current line. The portion of the screen from the current line inclusive to the bottom is scrolled upward by n lines. The n new lines scrolling onto the bottom of the screen are filled with spaces; the n old lines beginning at the cursor line are deleted. The position of the cursor on the screen is unchanged.

Takes one parameter, n (default 1). Deletes n characters starting with the current cursor position. Shifts the tail of the current line to the left by n character positions from the current cursor position, inclusive, to the end of the line. Blanks are shifted into the rightmost n character positions. The position of the cursor on the screen is unchanged.

Takes one parameter, n (default 0). Note that unlike most escape sequences, the parameter defaults to zero if omitted. Invokes the graphic rendition specified by the parameter. All following printing characters in the data stream are rendered according to the parameter until the next occurrence of this escape sequence in the data stream. With PROM-based emulator, only two graphic renditions are defined: 0

Takes no parameters. On SPARC, sets the screen mode to black-on-white. If the screen mode is already black-on-white, has no effect. In this mode, spaces display as solid white, other characters as black-on-white. The cursor is a solid black block. Characters displayed in negative image rendition (see `Select Graphic Rendition' above) are white-on-black. This comprises the initial setting of the screen mode on reset. On x86 systems, use ESC[q to set black-on-white.

Takes no parameters. On SPARC, sets the screen mode to white-on-black. If the screen mode is already white-on-black, has no effect. In this mode spaces display as solid black, other characters as white-on-black. The cursor is a solid white block. Characters displayed in negative image rendition (see `Select Graphic Rendition' above) are black-on-white. Initial setting of the screen mode on reset is black on white. On x86 systems, use ESC[p to set white-on-black.

Takes one parameter, n (default 0). Sets to n an internal register which determines how many lines the screen scrolls up when a line-feed function is performed with the cursor on the bottom line. A parameter of 2 or 3 introduces a small amount of jump when a scroll occurs. A parameter of 34 clears the screen rather than scrolling. The initial setting is 1 on reset. A parameter of zero initiates wrap mode instead of scrolling. If a linefeed occurs on the bottom line during wrap mode, the cursor goes to the same character position in the top line of the screen. When a line feed occurs, the line that the cursor moves to is cleared and no scrolling occurs. ESC [ 1 r exits back to scroll mode. For more information, see the description of the Line-feed (CTRL-J) control function above.

Takes no parameters. Resets all modes to default, restores current font from PROM. Screen and cursor position are unchanged.
