AT Commands
S-Registers
S Registers are 1 byte, volatile registers used to store configuration data. They are reset to the
default state whenever modem emulation is enabled, or the ATZ/AT&F command is received.
They can be saved to flash memory with the AT&W command. When the port is opened, the saved
parameters are applied to the port.
