/* The following documentation on was taken from "Linux Serial Programming
|
2000-02-17 20:38:33 +01:00
|
|
|
HOWTO". It explains how MIN (t->c_cc[VMIN] || vmin_) and TIME
|
|
|
|
(t->c_cc[VTIME] || vtime_) is to be used.
|
|
|
|
|
|
|
|
In non-canonical input processing mode, input is not assembled into
|
|
|
|
lines and input processing (erase, kill, delete, etc.) does not
|
|
|
|
occur. Two parameters control the behavior of this mode: c_cc[VTIME]
|
|
|
|
sets the character timer, and c_cc[VMIN] sets the minimum number of
|
|
|
|
characters to receive before satisfying the read.
|
|
|
|
|
|
|
|
If MIN > 0 and TIME = 0, MIN sets the number of characters to receive
|
|
|
|
before the read is satisfied. As TIME is zero, the timer is not used.
|
|
|
|
|
|
|
|
If MIN = 0 and TIME > 0, TIME serves as a timeout value. The read will
|
|
|
|
be satisfied if a single character is read, or TIME is exceeded (t =
|
|
|
|
TIME *0.1 s). If TIME is exceeded, no character will be returned.
|
|
|
|
|
|
|
|
If MIN > 0 and TIME > 0, TIME serves as an inter-character timer. The
|
|
|
|
read will be satisfied if MIN characters are received, or the time
|
|
|
|
between two characters exceeds TIME. The timer is restarted every time
|
|
|
|
a character is received and only becomes active after the first
|
|
|
|
character has been received.
|
|
|
|
|
|
|
|
If MIN = 0 and TIME = 0, read will be satisfied immediately. The
|
|
|
|
number of characters currently available, or the number of characters
|
|
|
|
requested will be returned. According to Antonino (see contributions),
|
|
|
|
you could issue a fcntl(fd, F_SETFL, FNDELAY); before reading to get
|
|
|
|
the same result.
