The non-standard 23-pin D-sub connectors for external floppy drives and video output on most of the Amiga computers are usually labeled DB-23, even though their shell size is two pins smaller than ordinary DB sockets. In the most simple case you may connect 3 pins only. DB-9 nearly always refers to a 9-pin connector with an E-size shell. If you don't need the flow control then you may not connect corresponding pins. Way but sends the stop signal out the CTS pin. When the computer is ready to receive some bytes it sets RTS to HIGH (+12V) and the flow of bytes to it resumes.įlow control signals are always sent in a direction opposite to the flow The low state of the RTS (Request To Send) signal equal to -12V means "Do not send to me" (stop sending). Then when a DTE (such as a computer) wants to stop the data sending into it, it sets To get RTS/CTS flow control to work you need to select a corresponding option in the Advanced Serial Serial Port Monitor supports both RTS/CTS and DTR/DSR flow controls.īoth flow control modes work the same way. We have already described it in the FlowĬontrol chapter but the pins and voltage signals were not. If devices RTS and CTS or DTR and DSR pins are coonnected then it means that the "hardware" flow control can be used. Note: DCD can be sometimes labeled as CD Hardware flow control: RTS/CTS and DTR/DSR
