I am writing routines for the serial port and I was wondering if setting the QNX (POSIX) flags “IHFLOW” and “OHFLOW” would have the same effect as setting the Linux “CRTSCTS” (Non-Posix) bit to enable hardware flow control?
eg: tio.c_cflag |= IHFLOW; // Enable INPUT hardware control
tio.c_cflag |= OHFLOW; // Enable OUTPUT hardware control
(Where “tio” is a termios struct)
Is the same as :
tio.c_cflag |= CRTSCTS; ???
As always, any help is very much appreciated.
