I was in the middle of installing rn on HP9000 series 300 running HP-UX6.5. I've got a syntax error saying "CBREAK not defined." I understand CBREAK is defined in ioctl.h on BSD Unix. But it was not the case on our machine. But, I know CBREAK mode is supported on HP machine. Could anyone tell me the mode which is equivalent to CBREAK mode? Thank you in advance. sukmi ------------------------- Please reply to: sukmi@psuvax1.cs.psu.edu

TIOCBREAK simulates a BREAK condition on a PTY (at least, that's what I think the text in pty(7) means). CBREAK on BSD is a "half-cooked" mode, similar to -icanon. -- Tor Lillqvist, working, but not speaking, for the Technical Research Centre of Finland

Appended below are cbreak() and normal() functions, which are equivalent to setting or clearing CBREAK, respectively. Credit for these goes to Dave Decot.

Clearing ICANON and setting the c_cc[VMIN] and c_cc[VTIME] "characters" to 0 causes behavior similar to BSD's CBREAK mode. Dave Decot

Note that the routine cbreak() also turns off echoing. If you don't want to do that, delete the portions that clear the ECHO flags (you usually do if you want to prevent the screen from getting messed up, so that's why this function also does that). Dave
