[comp.unix.wizards] Losing pending input in entering RAW or CBREAK

dfenyes@thesis1.med.uth.tmc.edu (David Fenyes) (05/03/91)

Hello,

I have an application that enters CBREAK mode (to do editing).
When I switch from cooked to CBREAK, any pending input appears
to be discarded.  How can this be avoided or worked around?

The exception is if a <CR> is hit before entering CBREAK--then the
whole line is properly read in CREAK mode.

I'm using Coherent.  Is this an anomaly, or standard tty behavior?
Is there any way to retrieve those chars not sent by <CR> in cooked
mode?

Thanks in advance,
