Amiga Explorer, like many other programs, additionally uses RTS and CTS for hardware handshaking, and DTR and DSR for each side to inform the other side whether it is ready to process data or not. This is accomplished by connecting GND (system ground) on both sides, and cross-connecting TxD (transmit data) with RxD (receive data). This should never be attempted, as it may damage one or both computers.įor some applications, including terminal software when no hardware handshaking is used, very simple null-modem cables with three wires are sufficient to exchange data (although not in the most reliable and efficient way). ![]() While a null-modem serial cable will not attach to it (as it also uses female connectors), certain other combinations of cables and gender changers can in theory be used to try to connect a parallel port on one computer with the serial port of another computer. Warning: the 25-pin female connector on the back of many computers is a parallel port (not a serial port).
