Does the ATMega in the Sanguino have its boot loader installed?
If so is the baud rate setting correct?
You should be able to run the Sanguino with the reset jumper removed then
you only need to get tx/rx the right way round and set the baud rate
appropriately.
You could try attaching a terminal program in your pc like screen on the
mac, picoterm/minicom on linux or putty in windows. The you can vary the
baud rate and watch for prompts from the Sanguino. The CPU tx and rx pins
should relax to logic 1 (+5V?) when the is no data and both lines are
correctly connected.

Have you done basic fault finding on the Sanguino like checking that 0v and
power are getting to the cpu pins and that the oscillator is running at the
correct frequency?
