I'm sure I'm just being stupid and over-looking something, not reading
the revelent parts of TFM, but I can't discover how to set cbreak mode
in ESIX. Stty cbreak is not a valid option, and there is no CBREAK flag
I can send to ioctl.
Could some kind person out there please describe the full extent of my
foolishness and tell me how to do this.

CBREAK is called ICANON under System V. Check out termio(7) in TFM. If you're lazy and don't want to do the terminal settings via an ioctl(2), Stty should have a "raw" option, aka cbreak. -- Arthur W.

No, "raw" and "cbreak" are different. "raw" means *RAW*, as in "no input processing of any sort, not even checking for the interrupt or quit characters, or for ^S and ^Q, and 8-bit input/output with no parity, and no *output* processing either". "cbreak" means "don't do input editing, i.e. no erase or kill character, *but* do *all* the output processing requested by the other mode bits, and check for the interrupt and quit characters, as well as for ^S and ^Q." Not the same at all.

The VTIME/VEOL >value *might* already be zero, but why take chances? It seems doubtful that someone would be using stty like this for anything fancier than "Press any key to continue". The setting of eol doesn't appear to make any difference it that application. It probably would make a difference elsewhere. -- Richard Foulk richard@pegasus.com
