[DSP-10] Testing KDSP10/DSPx

I do not use a null-modem cable between the KDSP10 and my PC.  I haven't
verified Hyperterminal works under Windows XP.  I used both a Windows 98 and
a DOS computer to test with.

Confirm that Hytertemrinal is set for the correct baud rate and serial port.

Try jumpering pins 2 and 3 at the KDSP10 end of the cable, but with the
KDSP10 disconnected.  You should see the characters you type echoed on the
screen.  This will test the PC and serial cable.

If this works, then verify the power supply voltages on the KDSP10 and the
DSPx.

Double check the orientation of all the ICs on the KDSP10.

Hope this helps,
