N1MM has two networks and this program had only one of them. Port 12060
carries XML to other programs — a spot tool, a score poster — and
`StationNetwork` already writes that. Computer to computer, N1MM uses
port 12070 and a different protocol, which is what this adds.
The wire format, from `MultiOpManager` and `MultiStation`:
DATA__07%SHACK-PC%QSO%2026-09-03 12:34:56%DL1ABC%…~__DATA
the sending station's number, its computer name, the message type and
the fields of that type. `%` and `~` cannot appear in a field, so N1MM
writes `!` in their place. `StationRecord` reads and writes that, and
holds what has arrived until a `~` says a message is whole: TCP hands
over half a message as often as two.
Discovery is a UDP broadcast to the same port, six fields wide.
**N1MM refuses a station whose version is not its own** — it says
"Software versions must match" and drops it — so the version this
program broadcasts is a setting rather than its own version, and a
station that says something else is kept in the list with `Refused` set
so the operator can see why nothing is arriving.
`StationLink` runs both sockets, opens a connection to every station it
hears, and reports what arrives. `QsoRecord` is the thirty-five fields
of a contact in N1MM's order, from `MultiOpManager.cs:1007`; points and
multiplier flags are read but the log works them out again from the
rules, so two stations cannot disagree about a score. `AddStation` names
a station by hand, for a network where a broadcast does not reach.
A station can also be named rather than heard, and one that is connected
may say nothing for a while, so `NetworkedStation` is heard-from as soon
as it exists. Left at nothing, the sweep that drops quiet stations read
every new station as quiet since the beginning of time and closed the
connection the moment it opened.
Tested as bytes and over loopback. Nothing has talked to a real N1MM.

Double-click a cell in the log window to change it. The columns follow the
contest exchange instead of being fixed in the XAML, so CQ WW gets a Zone
column and Sweepstakes gets Nr, Prec, Ck and Sec.
QsoEditor holds the column list and applies one field edit. Validation comes
from the ExchangeFieldKind the contest declared: a CQ zone is 1 to 40, an ITU
zone 1 to 90, a section is looked up in the ARRL list, a grid must parse.
A refused edit returns the reason and leaves the log alone, so the cell
reverts. Changing the callsign runs the country lookup again.
Delete, or the right-click menu, removes the selected contact after a
confirmation. Either way the log is rescored, so a multiplier the removed
contact held passes to the next contact that claims it.
Both go out to the other stations in N1MM's own messages: contactreplace
carries oldcall and oldtimestamp, contactdelete names the contact. An incoming
edit or delete is matched by contact id first, falling back to call plus
timestamp because N1MM does not know our ids.
Country, continent and the two prefixes were filled in twice, once when
logging and once when editing. They now come from CountryFields.

The function keys send through cwdaemon or a WinKeyer, with N1MM's message
macros. Escape stops sending.
Settings are read with the reflection serializer rather than a generated one:
the generated one hands back null for every property the file leaves out
instead of the value the property is declared with, which crashed the program
the first time a new setting was added.
