QsoRecord followed MultiOpManager.QSOString, a helper N1MM does not use
for the network. The messages use Contact.QSOString: 43 fields, the
continent before the contact type, and flags as numbers. N1MM converts
the multiplier flags with ToShort and threw on 'True', so every contact
logged here raised an error at the other computer.
The id now goes out as a GUID and is kept on arrival, which is what the
other station's checksum of a resync block is made over.

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.
