Line 33: ==Use for transmit keying== In many radio modem implementations, especially in amateur radio, the DTR is used to control transmission. The radio receives when DTR is not asserted, typically passing audio in to a software modem. When DTR is asserted the radio transmits audio coming from the software modem. In cases where the radio is controlled by serial commands (e.g. a [[~~Computer~~computer ~~Aided~~aided ~~Transceiver~~transceiver]] interface) the control data flows regardless of DTR state. ==See also==
