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.

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.

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.
