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

Other flags may be used (eg, xon/xoff characters) if your
hardware supports hardware "soft" flow control.
