:SYSTem:KEY <numeric value>
This command simulates the pressing of a front-panel key. The parameter <numeric
value> is a key code number. The following table shows the keys and their corresponding
number codes.
This command places an entry in the Key Queue just like the real pressing of a key on the
front panel. The maximum capacity of the key queue is 500.
Return
Numeric data transferred as ASCII bytes in <NR1> format. The number returned
represents a key last pressed in the front panel. A “-1” is returned when this key
queue is empty.
Notes
The key queue will be cleared after the counter has been turned off or after a *RST
command.
Save/recall operation does not apply on this value.
Key commands are sequential, but only in terms of processing other key commands
or getting into the key queue. The operation performed by the key command is not
guaranteed to be complete before processing of the next non-ley command. Be ware
of this when intermixing key commands and non-key commands.
