Opening `/dev/ttyACM*` with DTR asserted creates the `usb-cdc` broker client, starts UART1 if needed, and requests writer ownership. It becomes an observer if another client is writer. USB data is binary-transparent. Supported host line coding is 110–1000000 baud, 7/8 data bits, none/odd/even parity, and 1/2 stop bits; settings apply only while USB owns the writer lease and are not saved automatically.
Opening `/dev/ttyACM*` with DTR asserted creates the `usb-cdc` broker client, starts UART1 if needed, and requests writer ownership. It becomes an observer if another client is writer. USB data is binary-transparent. The host's CDC line coding is shown by `usb status` for diagnostics only; it does not alter UART1. Configure physical baud rate, framing, flow control, and DTR explicitly with `serial` commands and persist them with `serial save`.
