ENTERING
FUNCTION COMMANDS
A
function command
is
used
to
execute
an
action without having
to
repeatedly enter
the
same
series
of
keystrokes. There
are two
ways
to
enter function commands
on the
Ampex
230
plus,
pressing
the
FUNCT
key in
conjunction with another
key or
pressing
one of the
function keys.

the
FUNCT
key
To
enter
a
command using
the
FUNCT
key,
simultaneously press
the
FUNCT
key and the
desired second key.
Pressing
the
two-keys transmits
a
three-character sequence:
SOH
(start
of
header),
the
ASCII character
of the
second key,
and a CR
(carnage return).
For
example,
pressing
FUNCT/A
sends
the
