Confirmed from HB9HBY's log: ptt=true, yet the FT-891 dropped to RX between words during a CQ macro — while the same SCU-17 works in N1MM. Root cause: go.bug.st/serial drives DTR/RTS through GetCommState/SetCommState, which on the SCU-17's Silicon Labs CP210x drops the asserted RTS (PTT) the moment DTR (CW) is toggled. N1MM/WSJT use EscapeCommFunction, which sets one line without disturbing the other. OpsLog now drives the lines the same way: a new lineCtl abstraction with a Windows implementation (linectl_windows.go) that opens the COM port via CreateFile and toggles DTR/RTS with windows.EscapeCommFunction (SETDTR/CLRDTR/ SETRTS/CLRRTS). linectl_other.go keeps go.bug.st/serial for non-Windows builds. The serial keyer holds a lineCtl instead of a serial.Port. RTS (PTT) now stays asserted for the whole macro, so the rig holds TX between words. Promotes golang.org/x/sys to a direct dependency.
