Do I *need* a socket for putting a stamp in a breadboard?

I just bought a basic stamp 2sx integrated chip (without any board
like the board of education). I tried hooking testing it out by
putting it on a breadboard along with appropriate serial lines and
power supply, but when I try to download anything to it via the DOS
basic stamp program it says 'hardware not detected' (I've tried
running it from DOS and windows). I believe the problem might be the
lack of a good stamp to breadboard connection. Do I need a socket to
put the stamp correctly in the breadboard? As is (without a socket),
the chip doesn't seem to go very far into the breaboard holes. Thank
you very much for your help.

    If you are plugging your serial cable into a DB9 female connector which is
    connected to you breadboard, pins 5 and 6 on the breadboard DB9 need to be
    shorted together.

    do you mean pins 6 and 7? I'm just connecting the wires from my db9
    cable to the breadboard by plugging the wires directly into the
    breadboard.

    I presume you are connecting your serial cable to a DB9 connector which is
    connected to your breadboard. Pins 6 and 7 on the back of the breadboard DB9
    must be shorted together.

    You don't necessarily need a socket to wire up a
    stamp, I had one on a breadboard with stuff soldered
    directly to the pins for a while. But then I
    unsoldered everything and put it on a socket. Why?
    Because sockets are cheap, so I can have several
    projects revolving around one stamp. When I want to
    work on a different project I just unplug the stamp
    and have at it.

    On a similar note, does anyone have a socket part
    number for which the stamp fits completely into, i.e.,
    the "belly of the stamp" sits on the socket? On the
    ones I have found the stamp's pins are 1/8th inch (or
    so) longer than the socket is deep . . .

    The Textool socket I mentionned earlier: 3M2402-ND (DigiKey).
    The stamp's and any other IC's belly sits drectly on the socket.

    I have a BOE and replaced the original socket with a Textool-ZIF
    variant. Wile such a Textool costs about a thrid of a BS2 ($17),
    you just lift the lever and there is no chance to even bend a pin.
    An I change the stamp a lot.
