Be sure you have the serial connection set to 9600, 8 data bits, no parity, 1 stop bit and no flow control.
If you are still having problems, check your serial cable by connecting it to your PC and looping back pins 3 and 4 on the other end of the cable. You can use a bent paper clip to do this. Once you have pins 3 and 4 connected to eachother, everything you type in hyperterminal should appear on the screen. If this happens, it means your cable and PC serial port are OK. Then remove the paper clip and connect the cable to the switch. It should work.
From a Google search, it looks like that Belkin cable is a straight through. Dell requires a crossover (or null modem cable). Here is one from the Dell website that will work.
After pressing and holding the reset button I can establish a connection, however now the text is just gibberish. Odd letters and such. Any suggestions?
Great now if I can just figure out why I cannot connect to either of my 3248 via the console. I purchase these second hand, each one from a different person, and I have tried several diferent cables but get no response on the terminal screen. Tried connecting them to various systems using both Putty and Hyperterminal. I am about ready to give up and buy something else. Any suggestions on what else to try or why nothing is being displayed on the screen?
9600 baud, 8 data bits, no stop bit, 1 start bit, no flow control
If looping back pins 2 and 3 works, then the baud rate may have been changed on the switch, so try other speeds leaving the other settings alone.
If that does not work, then maybe you have a straight through cable and not a null modem serial cable. Ohm it out to see if pin 2 goes to ping 3 (and 3 to 2) on the other end.

That worked! The cable tested okay. No luck with the Console port on my switch. Is there a way to test the port?

My belkin cable says is has "crossed null-modem" wiring design.
The part number is: F3B207-10 Do I need something different?

This should work.
So another problem could be that the previous user changed the baud rate of the switch. Try all the different baud rates.

giberish indicates that the baud rate is wrong. Try different baud rates until you get the correct one. 9600 is the default.

Are you sure it is pins 3 and 4, when I do this nothing happens but when I loop pins 2 and 3 I get the suggested feedback.

You are correct. It is pins 2 and 3 and not 3 and 4..
