Hi,
I cannot intercept [CTRL]+[] key sequence from an application running in
a pterm.
No code is generated from kbhit().
Any idea ?
Thanks,
Alain.

Ctrl-what? I don’t see anything between the brackets…
No code is generated from kbhit().
Does it work in text mode? The qansi terminal protocol only defines a
certain number of Ctrl combinations, and there are a lot of key
combinations that don’t generate any characters.

CTRL-anything!

My problem is to receive any CTRL- combinaison. I was supposed to receive a
key code for any CTRL-key pressed.

What about function keys and cursor keys without Ctrl – do those work
for you?
How are you trying to read them? You must switch your terminal to raw
mode before you can see all the cursor and control keys. Otherwise, the
driver will use the ones it understands for line editing, and throw away
anything else…

Yes, cursors, function keys, work fine.

I read the keys with the following function:
inline char getch()
{
char ch;
struct timespec rqtp;
struct termios raw_tios =
{
/* c_iflag / 0,
/ c_oflag / 0,
#ifdef QNXNTO
/ c_cflag / (CREAD|HUPCL),
#else
/ c_cflag / (CREAD),
#endif
#ifdef QNXNTO
/ c_lflag / 0,
#else
/ c_lflag */ (IEXTEN),
#endif
};
struct termios tios;
rqtp.tv_sec = 0;
rqtp.tv_nsec = 5000000;
tcgetattr(0, &tios);
while (tcischars(0) == 0) {nanosleep(&rqtp, NULL);}
tcsetattr(0, TCSANOW, &raw_tios);
read (0, &ch, 1);
tcsetattr(0, TCSANOW, &tios);
return ch;
}
Thanks,
Alain.

I hate to say this, but your code works for me… I tried Ctrl-arrows
and a few letters and they all generated some data. But Ctrl-C killed
my test program.
