Here's where fish sets up the terminal characteristics. As Ian says, fish does
not disable VDSUSP, so control-Z generates a signal instead of being sent to
fish. If fish were smarter it might change this dynamically depending on what
bindings are installed.
void reader_init()
{
tcgetattr(0,&shell_modes); /* get the current terminal modes */
memcpy(&saved_modes,
&shell_modes,
sizeof(saved_modes)); /* save a copy so we can reset the
terminal later */
shell_modes.c_lflag &= ~ICANON; /* turn off canonical mode */
shell_modes.c_lflag &= ~ECHO; /* turn off echo mode */
shell_modes.c_cc[VMIN]=1;
shell_modes.c_cc[VTIME]=0;
// PCA disable VDSUSP (typically control-Y), which is a funny job control
// function available only on OS X and BSD systems
// This lets us use control-Y for yank instead
#ifdef VDSUSP
shell_modes.c_cc[VDSUSP] = _POSIX_VDISABLE;
#endif
