Control Octal Action Taken | |
Character Code | |
------------------------------------------- | |
NUL 000 Ignored on input (not stored in input buffer; | |
see full duplex protocol). | |
ENQ 005 Transmit answerback message. | |
BEL 007 Sound bell tone from keyboard. | |
BS 010 Move the cursor to the left one character position, | |
unless it is at the left margin, | |
in which case no action occurs. | |
HT 011 Move the cursor to the next tab stop, | |
or to the right margin if no further tab stops | |
are present on the line. | |
LF 012 This code causes a line feed or | |
a new line operation. (See new line mode). | |
VT 013 Interpreted as LF. | |
FF 014 Interpreted as LF. | |
CR 015 Move cursor to the left margin on the current line. | |
SO 016 Invoke G1 character set, as designated by SCS | |
control sequence. | |
SI 017 Select G0 character set, as selected by ESC ( sequ… | |
XON 021 Causes terminal to resume transmission. | |
XOFF 023 Causes terminal to stop transmitted all codes | |
except XOFF and XON. | |
CAN 030 If sent during a control sequence, the sequence is | |
immediately terminated and not executed. It also causes | |
the error character to be displayed. | |
SUB 032 Interpreted as CAN. | |
ESC 033 Invokes a control sequence. | |
DEL 177 Ignored on input (not stored in input buffer). | |
