17.4.9.3 Special Characters for Flow Control
............................................
These special characters may be active in either canonical or
noncanonical input mode, but their use is controlled by the flags 'IXON'
and 'IXOFF' ( Input Modes).
-- Macro: int VSTART
This is the subscript for the START character in the special
control character array. 'TERMIOS.c_cc[VSTART]' holds the
character itself.
The START character is used to support the 'IXON' and 'IXOFF' input
modes. If 'IXON' is set, receiving a START character resumes
suspended output; the START character itself is discarded. If
'IXANY' is set, receiving any character at all resumes suspended
output; the resuming character is not discarded unless it is the
START character. 'IXOFF' is set, the system may also transmit
START characters to the terminal.
The usual value for the START character is 'C-q'. You may not be
able to change this value--the hardware may insist on using 'C-q'
regardless of what you specify.
-- Macro: int VSTOP
This is the subscript for the STOP character in the special control
character array. 'TERMIOS.c_cc[VSTOP]' holds the character itself.
The STOP character is used to support the 'IXON' and 'IXOFF' input
modes. If 'IXON' is set, receiving a STOP character causes output
to be suspended; the STOP character itself is discarded. If
'IXOFF' is set, the system may also transmit STOP characters to the
terminal, to prevent the input queue from overflowing.
The usual value for the STOP character is 'C-s'. You may not be
able to change this value--the hardware may insist on using 'C-s'
regardless of what you specify.
