Ah... my eyes kept misreading it as \E[, not \E].
PMFJI, perhaps way late. In my recollection, from trying to debug
a terminal emulator, decades ago:
o VT100 has two distinct modes:
- one used by shell commands.
- the other used by vi, etc.
Curses may not need to deal with the former. And:
o ESC sequences are time sensitive. Vi uses ESC to exit text insertion
mode, distinguishing that use from ESC sequences generated by arrow
keys, etc. by the presence or absence of a pause after the ESC. I
can't imagine how this plays with the possibility that network packets
may by happenstance be split right after the ESC.
