## Disable SIGSTOP triggered by CTRL+S
```bash
# Disable
stty stop ''
# ReEnable = map stop top CTRL+S
stty stop '^s'
```

```python
import sys, termios

attr = termios.tcgetattr(sys.stdin)
# Save the value to be restored
bak = attr[6][termios.VSTOP]

# Disable SIGSTOP triggered by CTRL+S
attr[6][termios.VSTOP]=0
termios.tcsetattr(sys.stdin, termios.TCSADRAIN, attr)

'''. . . do stuff . . .'''

# reEnable SIGSTOP triggered by CTRL+S
attr[6][termios.VSTOP]=bak
termios.tcsetattr(sys.stdin, termios.TCSADRAIN, attr)
```
### Terminal Mapping:
 - CTRL-C -> termios.VINTR
 - CTRL-S -> termios.VSTOP
 - CTRL-Z -> termios.VSUSP
 - CTRL-Q -> termios.VSTART

Have a look at [test.termios.001.py](../../tests/test.termios.001.py)
