buffer if full. So now everything that uses outcom (including JS
console.write) now includes a retry. The lower-level non-retry outcom()
was renamed _outcom() (and is used by outcom).
Added new Ctrl-A code: Ctrl-AF - enables the blink attribute, but only
if/when a blink font was activated in the terminal. Lower-case 'f' refers
to the normal-intensity blink-font. Uppercase 'F' refers to the high
intensity blink-font. This allows you to mix fonts in text/menu files
and not have annoying blinking text in non-supporting terminals. This is
the first Ctrl-A code to be case-sensitive.
