Comment (by Quozl):

 summary: the ICRNL bit is missing from IFLAGS.

 workaround: type this command
 stty ircrnl

 diagnosis: a python program was used to read the termios flag bits;
 import sys, termios
 fd = sys.stdin.fileno()

 on 13.1.0 the output was [21760, ...], but on 14.1.0 the output was
 [21504, ...], showing that c_iflag was different in only one bit, ICRNL
 "Translate carriage return to newline on input".

 a test also showed the file descriptor was not set to O_NONBLOCK.

 previous diagnosis failed to use --all on stty.
