“S”: Status Inquiry
Use command S to request that status information be returned to the host. The status information
is sent as a string of L x O substrings, where L = number of levels and O = number of outputs.
Each level/output combination generates a single substring of status. Thus, a 21-level 16 output
router would generate 2x16 = 32 substrings of status command output. The length of each
substring depends on the size of the particular switcher involved. Larger switchers use bigger
numbers for inputs, outputs, and levels.
The first substring of status is for level 1 output 2, etc.; however, each substring contains the level
and output numbers, so the sequence in which the data is sent is not important). The first
characters of each substring are a space followed by “X”, then the output number, a comma
character, the input number connected to the output (or 0 if no connection exists), another
comma, and finally the level number at which the input-output pair is connected. For example, the
command:
**S!!
might have the following two substrings at the beginning of its response:
**x01, 12, 1 x02, 02, 1!!
This indicates that output 1 is connected to input 12 on level 1, and that output 2 is connected to
input 2 on level 1.
The number of digits used for each number is generally the maximum number of digits ever
required for that particular switcher. Thus, a switcher with between 10 and 99 inputs would use
two digits for the input number, and a switcher with less than 10 levels would use one digit for the
level number.
“C”: Clear Matrix
Use command C to request that the switcher matrix be cleared so that all outputs are
disconnected from inputs (in switchers where this is possible) or else all outputs at all levels have
input 1 as their source. This command can take several seconds to execute (depending on the
size of the switcher matrix). 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!!<CR>
“K”: Set Password
The command "K" is followed by a password, which may be 0 to cancel the previous password,
thus causing no password to be specified, or, it may be a value between 1 and 9999 to supply a
password, which remains in effect until another password (or password 0) is supplied in another
“K” command. The password is stored by the router under the remote address specified using an
“M” command, or under the control portís remote address if an “M” command was not specified
