| H A D | char-stdio.c | 12fb0ac0 Wed May 23 19:50:41 GMT 2018 Patryk Olszewski <patryk@fala.ehost.pl> char: Remove unwanted crlf conversion
This patch fixes a bug in serial that made it almost impossible for guest
to communicate with devices through host's serial.
OPOST flag in c_oflag enables output processing letting other flags in
c_oflag take effect. Usually in c_oflag ONLCR flag is also set, which
causes crlf to be sent in place of lf. This breaks binary transmissions.
Unsetting OPOST flag turns off any output processing which fixes the bug.
