12.2.6.3 Monitor Answer

The Secure SAM-BA Monitor answers any command with an acknowledgement message formatted as follows:

____,________,________#[<payload>]

opcode errcode length

where:

• opcode—4 characters of the command
• errcode—value of the error code
• length—in cases where the Monitor must send data, this field shows how much data is in the payload, thus how much data the host computer has to read.
• payload—optional data, depends on the command.
