"CLEAR": Clear Matrix
From Syntax Description
Host CLEAR Ask router to clear all router outputs.
Router (None)
All outputs are unlocked, input secures are
unsecured, and all outputs are either
disconnected or connected to input 1.
The command "CLEAR" requests that the switch matrix be cleared so that all outputs are
disconnected from inputs (in routers where this is possible) or else all outputs at all levels have
input #1 as their source (when disconnecting is not possible). If output locks are supported, all
output locks are removed by this command. If input security is supported, all input
secures are removed by this command. This command can take several seconds to execute
(depending on the size of the switch matrix), and therefore the OK response at the end of the
command string could be quite late. In order to help ensure that this command isn't accidentally
executed, it requires four additional characters following the "C" character, to spell out the word
"CLEAR" in full.
For example, the command:
**CLEAR!!
would clear the matrix, and when finished, the following response would be generated:
** OK !!
"V": Connect Levels
From Syntax Description
Host V out,in,in... Make a connection to an output on each level.
Router
(None or V/Y/X command, depending on
which "U" command argument is in effect,
see "U" command description.)
Optional status response.
The command "V" is used to request that a connection be made. It must be followed by an output
number, a comma, and a comma-separated list of input numbers, one for each level, up to the
number of levels in the router. Fewer than the number of levels may be specified if desired, and
the remaining levels will be left unchanged.
For example, the command:
**V12,7,8,9!!
says that connections are to be made to output 12: from input 7 on level 1, input 8 on level 2, and
input 9 on level 3.
An input number of 0 means the output connection is to be left unchanged.
An input number of '-' (dash) means the output is to be disconnected. If the router does not
support disconnected outputs, the output connection will be left unchanged.
