The modem: - V.42 error correction (LAPM) and V.42bis compression for the games that dial in sync mode, which were forced to async, and V.8bis and 56K (V.90/K56 speeds). - Receive and transmit FIFOs timed by the line's speeds, the TXFNF/TXHF status bits, and Power Smash's symmetric speed. - PPP waits for the game to speak first, on the network thread; this replaces the quarter-second delay on reads. - Its ID reports the country as USA, as upstream's. - Frames short or long, an XID with bad lengths, a REJ for a frame that is gone, a V.8bis message without its end, a V.42bis step-up of a dictionary not a power of two: none can read or write past a buffer, loop for ever or be refused wrongly any more. The Broadband Adapter could not be turned on: settings forced it off and nothing set it. The option "Expansion Port Device (Restart Required)" (reicast_network_device) chooses the modem, the adapter or nothing; the modem by default, as before. The adapter gets its link-change interrupt 10 ms after a reset, as KallistiOS waits for, frames under 6 or over 1514 bytes are dropped, and the network starts with the game's first frame and stops on a GAPS reset. DCNet: "Use DCNet" (reicast_dcnet, off by default) goes online through the dcnet.flyca.st relay instead of picoTCP, on the same network thread, non-blocking, without locks. Power Smash and Pro Yakyuu always go through it, as upstream has them. picoTCP: dns.flyca.st as the name server; a socket that is ready is read whole (an upload no longer stalls); the ports of Daytona, Sega Tetris, Golf Shiyouyo 2, Dee Dee Planet, Driving Strikers, Floigan and the Internet Game Pack. Stopping the network thread no longer waits for it. In the save state (V24), on a Dreamcast: the device chosen and what the modem (FIFOs, V.42, V.42bis, V.8bis) and the adapter (GAPS, its RAM, the RTL8139) hold, 34 KB. A live connection cannot be in a state: one loaded replays what came over the line at the times it came, and a line the state does not have hangs up, without waiting for the thread. tools/threads/pico_test.cpp tests the thread with the new interface, and DCNet against a stand-in relay.
