A modem that offers a connection to another project is found by six
characters derived from its project and itself (modemCode): a copy of the
project has another code, so no two modems offer the same one. The room
names its modems of other projects to F's relay at a start and none at a
stop; the relay pairs each offer with the first modem that joins its code,
one to one as Java's server modem takes one client, and passes the frames
between the rooms' threads. Every client hears how each modem stands
(`modems`: connected, waiting, taken, unpaired, ambiguous, detached, or
unavailable without F). The document keeps the connection and the code.
Measured on F with two threads: a ping from one project's notebook to the
other's goes through; a third project that wants the same code reads
taken, and takes it when the second stops; a deleted project's modem
leaves with its room.

Measured first: tools/java-oracle's ModemRun joins two networks by a pair
of Java modems over TCP on localhost. The modem has no card and adds no
delay of its own — a frame takes the cables on both sides, nothing more.
The core pairs the two enabled modems on a port (Swift's inProject, with
its conditions and cycle suppression) on Java's timing: no 20 ms. The
modem example of FILIUS now pings through instead of failing the core.
A modem of another project (relay) gives its frames to whoever runs the
engine and puts on its cable what comes back, with this engine's frame
and packet numbers; a frame dies after MAXIMUM_RELAY_HOPS trips.

Who started the simulation, "Pakete verwerfen" and the dropped packets move
from the toolbar into a properties sheet beside the surface. New in it: restart
the simulation, after asking. The room learns a restart message: stopped as by
stop, every capture, dropped frame and program window emptied, started anew
and named after who restarted; refused for readers and frozen projects, logged,
and waiting for asked blobs like a start.

One room per project for everyone in it, held by a few worker_threads,
each room with a replica of the document that Hocuspocus' direct
connection keeps open: changes go in, what the room writes comes back.
/sim?project=... signs in as /sync does and says refusals and partings
as the socket's closing; only a write grant changes the room. The state
names who started the simulation. After the last person the room stays
60 s, then stops, writes back and ends. Freezing stops a running
simulation and refuses to start one, deleting ends the room without
writing back, revoking lets the person go from the room too; a failed
thread ends its rooms, stopping the service stops them all.

ViewersRun takes the rows of Java's viewers from the firmware: a switch's
table, a home router's NAT table, each after its reset, and the frames
"Pakete verwerfen" drops while it is held. The core writes a frame as Java
does and resets the NAT's dynamic entries; the room sends both tables as
views, drops while any client holds the button, and sends the dropped
frames, begun anew with each start, with the clock their times of day are
written from; the editor opens a table with a tap on a switch or home
router and holds "Pakete verwerfen" in its toolbar, which now wraps on a
phone. This completes F4.6.

GnutellaWindowRun uses Java's Gnutella window on terminal-net beside the
line of GnutellaRun's story "search". The core cancels a search as Java
does (every connection of the program's own requests closed, passed-on
queries kept), lets the number of peers change and lists /peer2peer's
files; the room takes the window's actions and sends its view; the editor
shows Java's four tabs with Java's symbols. Not adopted from Java: a number
of peers of one digit only, a results table that keeps the last search's
rows, a files table that lags behind the folder.

Oracle EchoWindowRun uses Java's echo server and client windows as a
person does; SaveAfterRunRun echo saves what Java keeps after the run.
The room takes setActive with a port, connect/disconnect/send, sends
both views and writes the server's port and the client's target back.
The editor's windows show Java's buttons, fields and lines; a port that
is no port is marked and not handed over (Java's button throws).
Core fix: an empty message (one empty segment with the push, as Java's
erstelleSegmente makes) counted as a repeat and never arrived.

The oracle MailWindowRun uses Java's e-mail windows as a person does and
answers their dialogs. The core sets and saves the program's account,
deletes a mail, checks a form as Java's window does, and gives the server
its domain, new and removed accounts and the window's own line; the room
sends both programs' views and takes their actions; the editor has both
windows. Better than Java: a name field for a new account, a user name the
server has is refused, deleting hits the folder shown, a new domain goes
into the accounts file at once.

The oracle BrowserWindowRun uses Java's browser and web server windows as a
person does; the room keeps a browser window per computer and sends a
program window's view, the start names the person's language. The editor
shows the page in a sandboxed frame, links and forms go to the room, the web
server has its button, virtual hosts and lines. Better than Java: relative
images and links count from the page's folder, a mark stays in the page, the
error page from Java's template, the virtual hosts' file with complete rows.

A new oracle, TerminalWindowRun, types into Java's own command line
window: the window writes each line after its prompt, takes a blank
line, cls, reset and exit itself, keeps the lines for the arrow keys,
and keeps its text, history and working directory over a stop and a
start.
The room now holds a command line window per computer for everyone
(TerminalWindow), kept over stops; the protocol carries its lines and
the one way to read them (terminalScreen); the core goes on in the
working directory of the run before (continueIn). The desktop opens
programs in Java's frame, and the command line works with keyboard and
finger: grey on black, the prompt hidden while a command runs, history,
chips for the commands, Ctrl+C. The room's failure is now tested in the
browser.
Fixed: the room handed the engine the wall clock with fractions of a
millisecond, and a ping hung after its first timeout. The engine and
the room count whole milliseconds, as Java's clock does.

Java's mode buttons start and stop the room, now in a worker of the
editor's page (LocalSimHost), with Java's speed slider. While the
simulation runs the design is locked as in Java: no palette, no sheet,
nothing moves, no undo. Cables that carry a frame light up in Java's
green, and a tap on a computer opens its desktop: Java's title, the
software installation first, then the installed programs in the order
of Java's list for the language, a taskbar with the network icon and
the network as the simulation runs it. The room sends that over a new
topic, node:<id>. Desktops stay over a return to the design and show
again at the next start. The programs' windows follow from F4.6b.

packages/protocol holds the one list of /sim messages and checks every
field, naming what is wrong. packages/sim has the simulation room for F and
the web worker: the document's snapshot at start, the engine's clock on the
wall clock with Java's speed as cable delay, subscriptions to cable
activity, a card's new frames and a program's new window lines, capture and
clock kept over a stop, the command line as first action, a core failure
told to every client. LocalSimHost mirrors the document into the worker and
back without echo. M9 in Chromium: 17 examples give the same capture as in
Node, character for character; the room runs in a real worker.
