Comments:

The sock.allowedinterfaces property refers to the Ethernet interface as "NET", 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 dictates which GPIO lines must be used as inputs and which — as outputs.
CTS is permanently mapped to 0- PL_INT_NUM_0 (0- PL_IO_NUM_0_INT0). RTS is permanently mapped to 2- PL_IO_NUM_2.

Supported Objects, variable types, and functions

Sock — socket communications (up to 16 UDP, TCP, and HTTP sessions);
Net — controls the Ethernet port;
Ser — in charge of the RS232 port;
Io — handles I/O lines, ports, and interrupts;
Stor — provides access to the EEPROM;
Romfile — facilitates access to resource files (fixed data);

Pppoe — provides access to the Internet over an ADSL modem;
Ppp — provides access to the Internet over a serial modem (GPRS, POTS, etc.);

Pat — "plays" patterns on a pair of LEDs;
Button — monitors the MD line (setup button);
Sys — in charge of general device functionality.
Fully supported with the exception of fd.copyfirmware. Disabled by default — enable it in Project Settings -> Customize.

This platform supports the standard set of variable types and functions (a.k.a. "syscalls") except aes128enc and aes128dec. These AES128 functions are not present on the DS1100 platform.
