The sock.allowedinterfaces property refers to the Ethernet interface as "NET", Wi-Fi — as "WLN", PPP — as "PPP", and PPPoE — as "PPPOE". Sock.targetinterface and sock.currentinterface properties rely on the pl_sock_interfaces enum, whose members differ depending on the platform.

Surrounding board hardware and installed Tibbits dictate which GPIO lines must be used as inputs and which — as outputs.

Default CTS/RTS mapping is different for each serial port:

	RTS	CTS
Port 1	0- PL_IO_NUM_0	0- PL_INT_NUM_0 (16- PL_IO_NUM_16_INT0)
Port 2	1- PL_IO_NUM_1	1- PL_INT_NUM_1 (17- PL_IO_NUM_17_INT1)
Port 3	2- PL_IO_NUM_2	2- PL_INT_NUM_2 (18- PL_IO_NUM_18_INT2)
Port 4	3- PL_IO_NUM_3	3- PL_INT_NUM_3 (19- PL_IO_NUM_19_INT3)

Although the platform itself supports remapping, actual "wires" connecting the system to the GA1000 or WA2000 are fixed and your mapping should reflect this:

CS	PL_IO_NUM_49
CLK	PL_IO_NUM_53
DI	PL_IO_NUM_52
DO	PL_IO_NUM_50
RST	PL_IO_NUM_51

Supported Objects, variable types, and functions

beep — generates buzzer patterns using the onboard buzzer
bt — responsible for Bluetooth Low Energy (BLE) communications
button — monitors the onboard setup (MD) button
fd — manages flash memory file system and direct sector access
io — handles I/O lines, ports, and interrupts
kp — scans keypads of matrix and "binary" types1
lcd — controls graphical display panels (several types supported)2
net — controls the Ethernet interface
pat — "plays" patterns on up to five LED pairs
ppp — provides access to the Internet over a serial modem (4G/LTE, POTS, etc.)
romfile — facilitates access to resource files (fixed data)
rtc — keeps track of date and time
ser — in charge of serial ports (UART, Wiegand, and clock/data modes)
sock — socket communications (up to 16 UDP, TCP, and HTTP sessions)
ssi — implements up to four serial synchronous interface (SSI) channels, supports SPI, I2C, clock/data, etc.
stor — provides access to the EEPROM
sys — in charge of general device functionality
wln — handles the Wi-Fi interface (requires the GA1000 or WA2000 add-on module to be plugged into the TPP2 G2 board)

The kp. object can be configured to communicate with an external keypad connected to the TPP3(G2) board via Tibbit modules. Only one keypad can be serviced at a time.
This may be an external modem connected to the TPP3(G2) board or a 4G/LTE Tibbit module plugged into the board.

The TPP3W(G2) platform supports the standard set of variable types and functions (a.k.a. "syscalls").
