/* Users report:
|
||||||
|
* The resize command messes up the terminal.
|
||||||
|
* In my case it looks like it is hanging and
|
||||||
|
* I need to press ctrl-c to get a prompt.
|
||||||
|
* Actually the program does not hang but just
|
||||||
|
* the terminal is messed up.
|
||||||
|
* Replaced TCSANOW with TCSAFLUSH:
|
||||||
|
* "the change occurs after all output written to fd
|
||||||
|
* has been transmitted, and all input that has been
|
||||||
|
* received but not read will be discarded before
|
||||||
|
* the change is made.
