4.6 Control Commands in Detail

Each of the following commands speciﬁes a list of arguments and their meanings, the response format

returned if the command can be successfully executed. If the speciﬁcation does not include a list of

arguments, then none are required. If a description of the response format is not included, then the

“R-COMMENT” ﬁeld of the response shall be empty upon successful execution. In all commands

below, the response format assumes the “R-RESPONSE” and “R-SUMMARY” as deﬁned in the

MCS Common ICD [4]. The response format listed for each command describes the contents of

“R-COMMENT”. Commands which cannot be executed will return a “R” in “R-RESPONSE”, and

“R-COMMENT” will be set to the corresponding error message. No commands will be rejected

without returning a human-readable description of the reason in the “R-COMMENT” ﬁeld. Possi-

ble error messages and their meanings are listed in section 4.7.
