Reported: on a CQ macro the rig drops to RX between words instead of holding TX
for the whole macro. Root cause is PTT not being held (usePTT off, or the RTS
PTT line not wired/honoured). Improvements:
- "Key PTT line" now defaults ON when the Serial engine is selected — without it
the rig runs on semi-break-in and drops between words.
- The serial keyer's line options (PTT, key line, invert, lead/tail, speed) are
now atomic and live-updatable: SaveWinkeyerSettings -> ApplySerialConfig applies
them from the next character, no reconnect needed.
- Each transmission logs its PTT state / key line / lead/tail, so a rig that
still won't hold TX can be diagnosed from the app log.
The macro itself is sent as one string (not fragmented), so PTT is genuinely
held across word gaps when usePTT is on — pending on-air confirmation via the log.
Some CW interfaces key on the opposite line level (transmit at rest / key
backwards). New "Invert keying (active-LOW)" toggle flips the asserted level for
both the CW and PTT lines, and the idle state drives both lines to their
inactive level accordingly so an active-low rig isn't left keyed at rest.
Default off = N1MM convention (line HIGH = active).
Adds a 4th CW keyer engine alongside K1EL WinKeyer, Icom CI-V and Flex CWX:
OpsLog bit-bangs the Morse itself on a serial control line (DTR keys CW, RTS
keys PTT — swappable), the hardware-keying method N1MM/WSJT use with a Yaesu
SCU-17 and generic interfaces. No WinKeyer chip needed.
- internal/winkeyer/serialcw.go: serialKeyer — worker goroutine, morse table,
WPM + Farnsworth timing (live speed changes), abortable, PTT lead-in/tail/hang.
- winkeyer.Config gains Type ("k1el"|"serial") + CWKeyLine ("dtr"|"rts");
Manager routes Connect/Send/Stop/SetSpeed/Backspace/Disconnect to it.
- app.go: keyWKCWLine setting; WinkeyerConnect sets Type from the engine.
- Settings -> CW Keyer: new "Serial port (DTR=CW/RTS=PTT)" engine with COM port,
key-line selector, speed/Farnsworth/lead-in/tail/PTT. Macros, auto-CQ and
<LOGQSO> reuse the WinKeyer path unchanged.
UNTESTED on hardware (no SCU-17 to hand): polarity assumes N1MM convention
(line HIGH = active). Weight not yet honoured; Farnsworth is.
