[PATCH 2/3] vstatus: Add user space API definitions for VSTATUS, NOKERNINFO and TIOCSTAT
Walt Drummond
walt at drummond.us
Tue Jan 18 15:43:22 AEDT 2022
Add definitions for the VSTATUS control character, and the NOKERNINFO
local control flag in the termios struct, and add an ioctl number for
the ioctl TIOCSTAT. Also add a default VSTATUS character (Ctrl-T)
default valuses in termios.c_cc. Do this for all architectures.
