API Operation
An alternative to Transparent Operation are Application Programming Interface (API) Operations. API
operation requires that the device communicate through a structured interface (that is, data is
communicated in frames in a defined order). The API specifies how the device sends and receives
commands, command responses, and module status messages using a serial port Data Frame.
