READYCK
Purpose Read or set the ready check flag.
Command
Query “READYCK 1”
“READYCK?”
Classic “READYCK=1”
“READYCK”
Remarks The internal ready check flag is cleared whenever the PPCK+ reaches a Not Ready
(NR) condition. The "READYCK" query will return the status of this flag. This flag is
set by sending the "READYCK 1" program message while the PPCK+ is in a
Ready condition. You can then use “READYCK” program message query at a later
time to determine if a Not Ready (NR) condition has occurred since.

Purpose Lock out the front panel controls.
Command “REMOTE”

Remarks The PPCK+ goes into remote mode whenever communications take place. The user
can return to local operation by pressing the
[ESC] key. The REMOTE program
message locks out the front panel completely. The only way to unlock the front panel
is by using the LOCAL program message, the IEEE-488 ‘GTL’ command, or by
cycling the PPCK+ power.
