I obviously misunderstood the Q. DRRYAN3 has valid points. It might be worth a try though, with a Y connection. I don't think normal terminal programs start any handshaking automatically, if they're not set up to initialize a modem. Just make sure not to type anything during the session... I remember connecting a computer to a laboratory instrument using an RS232 link and Terminal from win3.11. If the program was running, characters started to appear immediately (if the instrument was transmitting) as I connected the serial link. (COM ports can normally take this brutal treatment, but I don't recommend it). As suggested above, some wires should perhaps not be connected, like transmit and flow control from "PC 2".
