might return the following string:
** QSmall~V2.1~ OK !!
indicating that the router model name is “Small” and the software version
number is “V2.1”.
“L”: Matrix Size and Level Names Inquiry
The command “ L ” requests that matrix size (Nout, Nlvl, Nin) and level name
information (lvl1, lvl2, etc.) be returned to the host. The information is sent as
a string of characters. The first characters are a space followed by “
L ”, some
optional values described below, then the number of outputs (Nout), a
comma, the number of levels (Nlvl), a comma, the number of inputs (Nin), a
comma, and then the level names, each terminated by a “
~ ” (tilde), and the
last followed by two tildes.
Routers can provide names for inputs, outputs, and levels. The number of
characters in a name can vary depending on the router model. The “
L ”
command provides access only to level names, and furthermore, it truncates
any level name that is longer than 6 characters to only 6 characters, in order to
retain compatibility with older routers and controlling devices that limited
level names OG-RTR 15 to 6 characters. Refer to the “
G ” command for
accessing input and output names and full-length untruncated level names.
The number of level names in the “ L ” command will be the same as the
number of levels that was given in the response (Nlvl). Valid characters for
level names are any printable (i.e. non-control) ASCII character (including
SPACE) except “
* ” (asterisk), “ ~ ” (tilde), and “ ! ” (exclamation mark). The
number of characters reported by the “ L ” command in level names may be no
more than 6 (longer names are truncated when reporting them with “ L ”). In
systems that do not support naming of levels, the level names will be fixed
number strings, e.g. “1”, “2”, etc.
For example, the command:
**L!!
might return the following string:
** L64,3,32,VIDEO~AudioL~AudioR~~ OK !!
indicating that the router has 64 outputs, 3 levels, and 32 inputs, and the levels
are named “VIDEO”, “AudioL”, and “AudioR”.
