Appendix A: Control Sequence Codes OS-9 V2.4 on EUROCOM-17
54 Software Manual
<ESC> represents the ASCII escape character
(<ESC>, <Ctrl>-[, $1B).
[ The next character is a left square bracket '[' ($5B).
<params> are a sequence of zero or more decimal numbers made up of
digits between 0 and 9, separated by semicolons.
<char> represents a function character which is different for each
control sequence.
CSI represents the ANSI control sequence introducer ($9B).
‘<ESC> [’ and CSI are alternate representations of the ANSI ‘Control
Sequence Introducer’ and may replace each other in any situation.
Some examples of syntactically valid escape sequences are:
<ESC> [ m select graphic rendition with default parameter
<ESC> [ 2 A moves cursor 2 lines up
<ESC> [ 10;5 H set cursor position
Supported Control Codes
• <CTRL>-H ($08) Backspace <BS>
The cursor moves one position to the left on the current line. If it is
already at the left edge of the screen, nothing happens.
• <CTRL>-J ($0A) Line-feed <LF>
The cursor moves down one line, remaining at the same character
position on the line. If the cursor is already at the bottom line, the screen
scrolls up one line.
• <CTRL>-M ($0D) Return <CR>
The cursor moves to the leftmost character position on the current line.
Supported ANSI Control Sequences
The syntax of the sequences follows the ANSI terminal standard, i.e.
arguments are to be given as readable ASCII strings, using decimal
notation, and are to be separated by semicolons. In the following
arguments will be indicated by short names enclosed in angle brackets.
Printing characters in the range '@'..'~' are regarded as terminating codes.
If they are defined in the following, they start processing the respective
function. Undefined terminating codes simply abort the sequence without
any action taken.
