To query a parameter value, just send the corresponding command letter fol-
lowed by the equality sign and a question mark character:
>
s=?[CR]
If the intended action does not need any parameter it is also sufficient in most
cases – as a shortcut – to send the command letter only, directly followed by
[CR].
At the beginning of a command sequence it is good practice to check the serial
communication by sending just a [CR] to the camera and verify that the com-
mand prompt
>
is returned.
Note
There is an input buffer holding a few characters but no hard-
ware handshake. Thus a sequence of commands should not be
sent to the camera without awaiting the intermediate input
prompts. This is especially important for serial command pro-
cessing through user-developed software routines. Otherwise
the camera’s serial input buffer may overflow.
