5.3 Protocol specifications
5.3.1 General description
The STP serial communication protocol enables the SIM to receive the communication command
transmitted from the PC and sends a response following the communication command (Figure 48-1).
Each communication command from the PC transmits a text message (ASCII text) assigned to each
function (Figure 48-2). Communication commands include control commands (STP pump operation
commands, etc.) and query commands (read-out of STP pump operation mode, etc.).
