2.5.2.6.3 Monitor Answer

The Secure SAM-BA Monitor answers any command with an acknowledgment 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 to SAM-BA, this field shows how much data is in the payload, thus how much data SAM-BA has to read.
  • payload—optional data, depends on the command.
