I seem to remember a message about this a long time back, but don't remember the details. I want to do single-character getchar()'s in C, but getchar() doesn't do genuine 1-char QIOs. It seems to want char + <ret>. Can cbreak mode easily be simulated without replacing the getchar() call with a qio? _H* ------

Something that I have used is the Screen manager routines, they are rather higher level than QIO and are used by VMS curses although VMS curses doesnt seem to simulate cbreak. If you are not using curses create a virtual keyboard: unsigned kb; SMG$CREATE_VIRTUAL_KEYBOARD(&kb); then use read_keystroke short key; SMG$READ_KEYSTROKE(&kb,&key); key is a short because function and arrow keys are coded as numbers out of ascii range. I used this method to add arrow key support for the VMS Rogue that was posted a while back.
