I am using this great object and need to know what the state is for the CTS and RTS. Whats the default state? Is CTS set low on a Clear to Send or High? Same with the other?

    It looks like RTS is set high if there's enough room left in the receive buffer with the threshold (in bytes) set in the addport call. RTS is set in the receive routine when there's no start bit present (when the receiver is idle) and it's initially set to low (until the first idle slot occurs).

    CTS is an input and must be high (if enabled) for the transmit routine to send a character.

    Either or both RTS and CTS can be inverted.
