The interaction of the iflag bits is as follows (parity error
given as an example):
Parity error INPCK IGNPAR
- None n/a n/a character received
- Yes n/a 0 character discarded
- Yes 0 1 character received, marked as
+ n/a 0 n/a character received, marked as
TTY_NORMAL
- Yes 1 1 character received, marked as
+ None 1 n/a character received, marked as
+ TTY_NORMAL
+ Yes 1 0 character received, marked as
TTY_PARITY
+ Yes 1 1 character discarded
Other flags may be used (eg, xon/xoff characters) if your
hardware supports hardware "soft" flow control.
