+- **Auto Reconnect is now Auto Connect**, as in the C# version: while it is on and no port is
+  open, the app connects to the selected port as soon as it can, also at startup and when the
+  device is plugged in for the first time. Disconnect (or Cancel while waiting) turns it off.
+  When the port is listed but cannot be opened (in use by another program), it says so and

+- Defaults for new installs (saved settings are kept): **DTR and RTS off** (were on), so that

+  defaults match the C# version: no line ending (was LF), Send with Enter on (was off), Line

+- The Send box uses a larger font than the receive view, as in the C# version.

 - A plotter line with `name=value` pairs was taken as the CSV header when it came first.

+- A lone CR now ends a line, as in the C# version; devices that end lines with CR only were
+  shown as one long line.
+- Hex send accepts the C# separators and one-digit bytes (`0A-0B`, `1,2,3`, `0x41`). Before,
