lchat: clean up terminal preparation |
|
|
|
- reuse the value of `origin_term' instead of calling tcgetattr(3) twice |
|
- change the following termios flags: |
|
IMAXBEL - is an extension and does not provide much "real" value |
|
OPOST - is mostly IB and thus not very useful |
|
ECHONL - only has an effect if ICANON is set, which isn't the case for us |
|
