A modem is a device that lets your computer talk over phone lines. You should not have any rj11s near your bns; only serial cables. There are 2 layouts most commonly used for serial ports, the pc style (dte) and the modem style dce. The blazer has a pc-style wiring on it but the gender is female. You need to connect pc to pc so you need a null modem. This is like in nedworking where you wish to connect pc to pc with no hub or switch you need a cross-over cable. A null modem is a device or cabling wire map that allows 2 computers to talk to each other over a serial link. Assume we have 2 computers with a 9-pin serial connection wishing to talk to each other. The cable in use is a straight through. Pin 2 is transmit and pin 3 is receive and 5 is signal ground. If the pins are wired straight through then the transmit and receive pins are wired transmit to transmit and receive to receive. This will not work as the transmit pin on one computer needs to be wired to the receive pin on the other. A null modem or cable does this for us. Usually it's wired as 2 to 3, 3 to 2, (transmit to receive) 5 straight through (signal ground) 4 to 6, 6 to 4, (cts to rts) Then cd is tied on one end to dsr and possibly dsr. ----- Original Message ----- From: "Cody Hurst" To: "Speakup is a screen review system for Linux."

When I plug the rj11 end of the cable to the pc, how do I tell speakup to look on teh modem port if linux by default is in compatible with most modems?
