COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
IRC requires a complete null-modem cable connection to operate correctly. For
proper connectivity, the serial port signals must be wired in a fashion identical
to the diagram shown in Appendix B. As shown in the diagram, the managed
server serial port transmit (TX or TxD) must be wired to the serial port receive
(RX or RxD) of the terminal server. Similarly, the managed server serial port
receive (RX or RxD) must be wired to the serial port transmit (TX or TxD) of
the terminal server. For proper flow-control, the request-to-send (RTS) and
clear-to-send (CTS) signals must be similarly cross-wired. The data-terminal-
ready (DTR) of the managed server must be connected to both the data-carrier-
detect (DCD) and the data-set-ready (DSR) of the terminal server. Similarly,
DTR signal of the terminal server must be connected to both DCD and DSR of
the managed server. The DTR and DCD cross-connections are extremely
important. Improper connection of these signals inhibits the ability to open a
connection to IRC. Lastly, the ground (GND) connection of both devices must
be connected together.
