Some while ago I got some problems with stty, so I wanted to test this
using checkpc with the T option. It turns up that the serial line you
specify on the command line was never used. See the patch for details.
Also, I changed the the stty command so it assumes to work on stdin and
report on stdout, except on old BSD and SunOS systems. Can anyone name
some systems with a stty command which works on stdout and reports on stderr
other than the old BSD systems, and are these systems still in active use?
I myself have never seen a stty command wich didn't work on stdin, that is,
several SVR2 and SVR3 derivatives including SCO xenix and unix.
